737NG Operations Manual
Preface
Chapter P1
Introduction
Section 2
General
The Boeing Company developed normal and non-normal procedures for the
737NG aircraft. Delta Air Lines has modified some of the procedures for
simplification and standardization, when appropriate with other Delta aircraft.
Finally, the FAA has approved the procedures presented in the Operations Manual,
with the exception of flight crew bulletins.
These procedures are company policy for pilots to follow during ground operations
and in flight. Deviations from these policies and procedures should be made only
with good cause and based on the safest course of action. If an abnormality occurs
that is not covered by these procedures, the Captain must use his best judgement.

Corrections to the Manual
To correct any errors or discrepancies discovered in this manual, or to submit a
suggested change to any Aircraft Operating Manual (Volume 1, Volume 2, QRH,
Flight Crew Training Manual), Normal Checklist, Airway Manual, Flight
Operations Manual (FOM), OE/TOE Guide, Flight Crew Bulletin (FCB), or Flight
Operations Bulletin (FOB):
Log on to the Delta Flight Operations Portal, http://dlnet.delta.com and submit a
Publications Change Request (PCR).
There are links to the PCR form on each fleet page and also on the Flight Ops
Manuals/Library Services page.
Once submitted, the PCR is automatically routed to the applicable Fleet Technical
Manager and Technical Writer for that manual.
Organization
The operations manual is organized in the following manner.
Volume 1
• Preface – contains general information regarding the manual’s purpose,
structure, and content. It also contains lists of abbreviations, a record of
revisions, a list of effective pages and flight crew bulletins.
• Limitations and Normal Procedures – cover operational limitations and
normal procedures. All operating procedures are based on a thorough
analysis of crew activity required to operate the airplane, and reflect the
latest knowledge and experience available.
• Supplementary Procedures – covers those procedures accomplished as
required rather than routinely on each flight.
• Aircraft Differences chapter notes differences between aircraft types.
Volume 2 - Chapters 1 through 15 contain general airplane and systems
information. These chapters are generally subdivided into sections covering
controls and indicators and systems descriptions.
Quick Reference Handbook (QRH) - The QRH covers normal checklists,
non-normal checklists and non-normal maneuvers.
Flight Crew Training Manual (FCTM) - The Flight Crew Training Manual
provides information and recommendations on maneuvers and techniques.

Preface Introduction
737NG Operations Manual
Page Numbering
The operations manual uses a decimal page numbering system. The page number
is divided into three fields; chapter, section, and page. An example of a page
number for the Normal Procedures chapter follows: chapter NP, section 20, page 3.
Example Page Number
Chapter (Normal Procedures)
Page Number
NP.20.3
Section (Amplified Procedures)
Warnings, Cautions, and Notes
The following levels of written advisories are used throughout the manual.
WARNING: An operating procedure, technique, etc., that may result in
personal injury or loss of life if not carefully followed.
CAUTION: An operating procedure, technique, etc., that may result in
damage to equipment if not carefully followed.
Note: An operating procedure, technique, etc., considered essential to emphasize.
Information contained in notes may also be safety related.
Airplane Effectivities
Differences in airplane configuration are shown by use of airplane effectivities
throughout Volumes 1 and 2, Quick Reference Handbook, and the Flight Crew
Training Manual. The following rules are used to express airplane effectivities:
• Airplane effectivities are listed by ship number. A range of airplanes is
defined by a dash, e.g. Ships 3101 – 3110. A comma in the effectivity
range indicates a break in the range, e.g. Ships 3701 – 3710, 3712 – 3725;
airplane 3711 is excluded from the range.
• Airplane effectivities apply only to the paragraph, illustration, operational
note, procedural step, etc. and to subordinate items (if any). Refer to the
examples below.

June 9, 2008
P1.2.3
Preface Introduction
737NG Operations Manual
Example 1 (with subordinate items):
Ships 3101 – 3110
If the PSEU light does not extinguish when the parking brake is set
or when both engines are shut down:
Do not takeoff.
Note: The PSEU light illuminates on the ground only.
In this example, the effectivity 3101 – 3110 applies to the first procedural step (If
the PSEU.....) and any additional indented/subordinate steps (Do not takeoff). The
effectivity does not apply to the next equivalently indented step (Note: The PSEU
light...).
Example 2 (without subordinate items):
Ships 3101, 3102
CAUTION: When gross weight is greater than 143,000 lbs, speed brake
will autostow to the 50% flight detent if airspeed exceeds 320 knots.
Do not overide autostow function unless airspeed is less than
320 knots.
Speedbrake . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . DOWN detent
In this example, the effectivity Ships 3101, 3102 applies to the first operational
caution only. The effectivity does not apply to the next equivalently indented step.
For clarity, an "All" effectivity may be applied to differentiate common steps from
those effected by specific ship numbers.
When airplane effectivities are centered immediately below a section or checklist
title, the entire section or checklist applies to the listed airplanes. In the following
example, the Emergency Equipment section below is applicable to Ships 3701 –
3771 only:

737NG Operations Manual
General
Delta Air Lines issues operations manual revisions to provide new or revised
procedures and information. Formal revisions also incorporate appropriate
information from previously issued Flight Crew Bulletins.
The revision date is the approximate date the revision material is distributed and
considered current. The revision should be incorporated as soon as it is received,
but may be incorporated as much as 21 days after the revision date.
Formal revisions include a Transmittal Letter, a new Revision Record, Revision
Highlights, and a current List of Effective Pages. Use the information on the new
Revision Record and List of Effective Pages to verify the operations manual
content.
The Revision Record should be completed by the person incorporating the revision
into the manual.
Filing Instructions
Consult the List of Effective Pages (P1.5). Pages identified with an asterisk (*) are
either replacement pages, new (original) issue pages, or deleted pages. Remove
corresponding old pages and replace or add new pages. Remove pages marked
DELETED; there are no replacement pages for deleted pages.
Be careful when inserting changes not to throw away pages from the manual that
are not replaced. The List of Effective Pages determines the correct content of the
manual.
Revision Highlights
This section (P1.4) replaces the existing section P1.4 in your manual.
Pages containing revised technical and non-technical material have revision bars
associated with the changed text or illustration.
Re paginated material not containing technical revisions are identified only by a
new page date.

Introduction
Chapter NP
Section 10
NP.10 Normal Procedures-Introduction
General
This chapter contains Normal Procedures. It incorporates routine normal
procedures and associated flight patterns.
Controls and Indications – Nomenclature
Controls and indications appear in all UPPERCASE type to correspond to the
words on the control panel or display. For example, the following item has
UPPERCASE words to match what is found on the panel:
APU GENERATOR switch ................................................................ON
The word GENERATOR is spelled out even though it is abbreviated on the panel.
The following appears in all lower case because there are no words identifying the
panel name or control position.
Mode control panel ............................................................................. Set
Normal Procedures
Normal procedures are used by the trained flight crew to ensure airplane condition
is acceptable and that the flight deck is correctly configured for each phase of
flight. These procedures assume all systems are operating normally and automated
features are fully utilized. The procedures also assume that systems are not
deactivated unless directed by procedure or required by an emergency situation.
Procedures are performed from recall and follow a panel flow. Checklists are used
to verify that critical items affecting safety have been accomplished. These
procedures are designed to minimize crew workload and are consistent with flight
deck technology.
FCOM Template 12/12/98
During accomplishment of procedures, it is the crew member’s responsibility to
ensure proper system response. If an improper indication is noted, first verify that
the system controls are properly positioned. Then, if necessary, check the
appropriate circuit breaker(s), and test related system light(s).
Before engine start, individual system lights are used to verify system status. If an
individual system light is indicating an improper condition prior to engine start,
determine if the condition may affect dispatch and require maintenance action or
compliance with the Mechanical Dispatch Manual (MDM).

NP.10.1
Normal Procedures Introduction
737NG Operations Manual
After engine start, the MASTER CAUTION system, annunciator lights, and alerts
are used as the primary means to alert the crew to a non-normal system condition.
Illumination of the MASTER CAUTION and system annunciator lights requires
accomplishment of the appropriate non–normal procedure. Upon completion of
the procedure and prior to takeoff, the Mechanical Dispatch Manual (MDM)
should be consulted to determine if MEL relief is available.
The panel illustrations in this section describe the amplified procedures preflight
panel flow and areas of responsibility during flight. A normal panel flow is
encouraged; however, certain items may be handled in the most logical sequence
for existing conditions.
General phase of flight responsibilities are as follows:
Pilot flying (PF):
• flight path and airspeed control
• airplane configuration
• navigation.
Pilot Monitoring (PM):
• checklist reading
• communications
• tasks requested by PF
• start levers and fire switches (with PF concurrence).
Phase of flight duties, beginning with the Takeoff Procedure and ending with
completion of the Landing Roll Procedure, are presented in table form in the
appropriate procedures section.
The First Officer, when flying the airplane, performs the duties listed under PF,
and the Captain performs those duties listed under PM.
Note: During flight with the autopilot engaged, the PF is primarily responsible
for updating the mode control panel. However, the PM may update the
mode control panel as directed by the PF. During manual flight, the PM
should manipulate the mode control panel as required.
The Captain retains final authority for all actions directed and performed.

Normal Procedures Introduction
737NG Operations Manual
Autopilot Flight Director System and Flight Management
System Monitoring
When the autopilot, flight director, or autothrottles are in use and a mode change
is selected or is scheduled to occur, the annunciation must be verified on the flight
mode annunciation display. Airplane course, vertical path, and speed must always
be monitored.
Similarly, when a thrust mode change is selected or is scheduled to occur, the
annunciation must be verified on the thrust mode display.
In LNAV and VNAV, all airplane course, vertical path, thrust and speed changes
must be verified.
RVSM Operations and System Requirements
Refer to the Airway Manual, Chapter 7, Navigation, Reduced Vertical Separation
Minimum (RVSM) section.
CDU Operation
On the ground, the control display unit (CDU) entries are normally performed by
the PF and verified by the PM.
In flight, with the autopilot engaged, CDU entries are normally accomplished by
the pilot flying and verified by the pilot monitoring prior to execution. With the
autopilot not engaged, CDU entries are accomplished by the pilot monitoring with
concurrence from the pilot flying. CDU manipulations should be accomplished
prior to high workload periods such as departure, arrival, or holding. During high
workload periods, using the autopilot modes such as heading select, level change,
and the altitude and speed intervention features, may be more efficient than
entering complex route modifications into the CDU.

Crew Duties Reference Chart
The Crew Duties Reference Chart below indicates normal divisions in pilot work
load. This chart serves as a guide to help crew members coordinate their duties
during a typical flight.
• Items not highlighted are required on every flight.
• Items highlighted with gray shading are required during Class II
navigation only.
• If operating in class II airspace for one hour or less, the only class II
navigation duties required are those identified with (N).
The chart delineates areas in which a crew member must remain reasonably
proficient if crew coordination is to be maintained at an optimum level.

Standard Callouts
The callouts in the following table are for normal line operations. During takeoffs
and approaches, the Pilot Monitoring (PM) will monitor flight mode annunciator
progression.
Some callouts are made automatically by aircraft aural systems. When a required
callout is made automatically, it may be omitted by the appropriate crew member.
On any approach, when the Pilot Flying (PF) can maintain visual contact with the
runway, the “APPROACHING MINIMUMS” and “MINIMUMS” callouts are
not required. On non-ILS and CAT I approaches, the PM will annunciate visual
cues. On CAT II and CAT III approaches, the Captain will annunciate visual cues.
Note: White and amber landing altitude reference bars on the PFD altimeter tape
are based on height above touchdown, and may be used to approximate
AGL at most airports.
Note: If the Radio Altimeter is inoperative, reference the barometric altimeter for
the “1,000” and “500” callouts.
The following callouts will be verbalized by the appropriate crew member:

Engine Start Procedure
The Captain should determine engine taxi configuration after considering
aircraft weight, ramp conditions, taxiway and maneuvering requirements.
• Single engine taxi out using No. 2 engine is the normal procedure,
conditions permitting.
• Single engine taxi out using No. 1 engine is permitted, but must be
coordinated with the ground crew.
Note: When departing from ramp areas where taxiing is restricted to
both engines, consider shutdown of one engine after exiting the
restricted area.
Refer to Delayed Start procedure for starting second engine.
APU bleed valve .................................................................... As required
APU bleed valve must be closed when:
• ground air connected and isolation valve open
• engine no. 1 bleed valve open
• isolation and engine no. 2 bleed valves open.
Note: APU bleed valve may be open during engine start, but avoid
engine power above idle.
Note: One pilot will accomplish the engine start procedure; the other
will monitor outside the flight deck. The Captain will brief start
duties and announce the start sequence.

CAPTAIN*
FIRST OFFICER
* Captain may delegate engine start procedure as deemed necessary.
Announce engine start sequence.
Normal starting sequence is 2, 1.
Call “START ENGINE No.____.”
Position ENGINE START switch to
GROUND.
Observe START VALVE OPEN alert.
Verify oil pressure increase by idle, N1 rotation, and N2 rotation.
Position engine start lever to IDLE detent when N2 rpm reaches maximum
motoring (25% minimum) and N1 rotation observed.
• At times, the APU cannot accelerate an engine to 25% N2. In this case
the engine start lever may be placed to IDLE at a minimum of 20% N2;
however, the higher the rpm prior to adding fuel, the cooler the start.
Verify fuel flow and EGT indication.
Note: An abnormal start advisory is indicated by the white box
surrounding the EGT digital readout flashing. If this advisory occurs,
continue to monitor other engine indications and abort the start if
necessary.
At 56% N2 RPM:
• ENGINE START switch moves to OFF automatically; if not, position
start switch to OFF.
• Verify START VALVE OPEN alert extinguishes and report “STARTER
CUTOUT.”
Monitor N1, N2, EGT, fuel flow and oil pressure for normal indications as
engine accelerates and stabilizes at idle. Ensure EGT peaks prior to starting
other engine.
Repeat procedure to start remaining engine as required.
Note: Standard day, sea level, approximate stabilized idle indications
for the CFM56–7 engine.
• N1 RPM – 20%
• N2 RPM – 59%
• EGT – 410°C**
• Fuel Flow – 600 PPH
** Idle EGT may vary from 320°C – 520°C depending on OAT, bleed
configuration, and engine conditions.
Starter Duty Cycle
• Limit each start attempt to a maximum of 2 minutes
• A minimum of 10 seconds is required between start attempts

Normal engine start considerations:
• Advancing engine start lever to idle prematurely can cause a
“HOT” start.
• Keep hand on engine start lever while observing RPM, EGT and
fuel flow until stabilized.
• If fuel is shutoff inadvertently (by closing engine start lever) do
not reopen engine start lever in an attempt to restart engine.
• Failure of ENGINE START switch to hold in GRD until starter
cutout RPM is reached can result in a “HOT” start.
CAUTION: Re-engagement of starter with N2 in excess of 20%
will result in serious damage to starter and engine.
Accomplish the ABORTED ENGINE START checklist for one or more
of the following abort start conditions:
• the N1 or N2 does not increase or increases very slowly after the
EGT increases
• there is no oil pressure indication by the time that the engine is
stabilized at idle
• the EGT does not increase by 10 seconds after the engine start
lever is moved to IDLE
• the EGT quickly nears or exceeds the start limit.

• HUD usage is required when conditions are below RVR 500. See Airway
Manual chapter 3 - Procedures (Ops Specs).
• Refer to the Supplementary HUD Takeoff Preparation procedures and the
Standard Callouts table in the Normal Procedures Introduction section for
instructions.
LNAV Departure
If the LNAV mode is to be utilized immediately after takeoff and the aircraft
symbol is not in close proximity to the departure end of the runway, accomplish
the following:
• Set the parking brake
• Reduce ND scale to the 10 nm range
• Enter the present latitude and longitude in the FMS POS INIT page
referencing the appropriate airport diagram in the Airway Manual.
• Perform the IRS Fast Realignment procedure
• Verify the aircraft symbol is now in close proximity to the departure end
of the runway on the ND.
Note: LNAV may be armed prior to takeoff.
CAUTION: Do not use LNAV for departure if FMS position is incorrect.
Takeoff Flaps
The AWABS system is enabled to offer takeoff settings of Flaps 1, 5, 10, 15, or
25. Settings may vary from day to day, or from runway to runway at the same
airport, as field conditions change.
Check AWABS for performance capability and appropriate V speeds. It is
imperative that crew members always check and verify flap settings, assumed
temperatures, N1, V-speeds and stabilizer trim setting for the assigned takeoff
runway are set correctly.
Review the Takeoff Flap Retraction Speed Schedule in section NP.20 of this
manual for the appropriate takeoff flap setting retraction schedule.
Flaps 1, 5, 10, 15 or 25 Takeoff
• Use normal rotation rate.
• Engine failure procedures remain the same for all takeoffs.
• Limit bank angle to 15 degrees until reaching V2 + 15.
• At acceleration height, retract flaps on flap speed schedule.
• Refer to AM 10-0 pages for any airport specific additional information.

If operable, the HUD or both an autopilot and a flight director will be used for all
ILS approaches when the reported visibility is below RVR 4000 or 3/4 mile.
Flaps 15 Landing
When a flaps 15 landing is desired:
• Position the GROUND PROXIMITY- FLAP switch to INHIBIT.
Note: If above 250 knots, the GPWS INOP light may illuminate.
Use flaps 15 for go-around
• If any of the following conditions apply, set VREF ICE (VREF 15 + 10):
• Engine anti-ice will be used during landing
• Wing anti-ice has been used anytime during the flight
• Icing conditions were encountered during the flight and the landing
temperature is below 10° C.
Note: When VREF ICE is required, the wind additive should not exceed 10
knots.
HUD Approach/Landing
The HUD may be used for all approaches and landings.
For more information, refer to Normal Procedures, Introduction (Section 10),
Standard Callouts, HUD Operative and Used for the Approach equipment
requirements, and also Amplified Procedures (Section 20).

Stabilized Approach Requirements
Maintaining a stable speed, descent rate, and vertical/lateral flight path in landing
configuration is commonly referred to as the stabilized approach concept.
Any significant deviation from planned flight path, airspeed, or descent rate must
be verbalized. The decision to execute a go-around is no indication of poor
performance.
WARNING: Do not attempt to land from an unstable approach.
IMC
At 1,000 feet AGL, and on final, the aircraft must be:
• Configured for landing.
• Maintaining stabilized descent rate not to exceed 1,000 FPM.
Note: If a published approach procedure requires a sink rate greater than
1,000 FPM, a special briefing should be conducted.
• On target airspeed within tolerance, or speed being reduced toward target
airspeed if higher was necessary.
• Established on course.
By 500 feet AGL, the aircraft must be:
• On target airspeed within tolerance.
WARNING: These conditions must be maintained throughout the rest of
the approach for it to be considered a stabilized approach. If
the above criteria cannot be established and maintained,
initiate a go around.
At 100 feet HAT for all approaches, the aircraft must be positioned so the flight
deck is within, and tracking so as to remain within, the lateral confines of the
runway extended.
VMC
At 1,000 feet AGL and on final, the aircraft must be:
• Configured for landing.
• Maintaining stabilized descent rate, not to exceed 1,000 fpm.

By 500 feet AGL, the aircraft must be:
• On target airspeed within tolerance.
• Lined up with runway except:
• Where the instrument approach or local procedures (such as River
Visual at DCA) dictate otherwise.
• Maneuvering (including runway changes). Maneuvering below 500
feet is not recommended unless the Captain has determined the
operation to be safe after considering:
• Descent rate change to acquire glide path not excessive.
• Runway lateral displacement.
• Runway threshold stagger.
• Tailwind/crosswind components.
• Runway length available.
WARNING: These conditions must be maintained throughout the rest of
the approach for it to be considered a stabilized approach. If
the above criteria cannot be established and maintained,
initiate a go-around.
At 100 feet HAT for all approaches, the aircraft must be positioned so the flight
deck is within, and tracking so as to remain within, the lateral confines of the

Crossing the Runway Threshold
As the aircraft crosses the runway threshold it must be:
• Stabilized within tolerance on target airspeed until arresting descent rate
at flare.
• On a stabilized flight path using normal maneuvering.
• Positioned to make a normal landing in the touchdown zone, i.e., first
3,000 feet or first third of the runway, whichever is less.

Non-ILS Approach Considerations
Approach Modes
There are several roll modes, [Integrated Approach Navigation (FAC, VOR/LOC,
BCRS), LNAV, VOR/LOC, or HDG SEL] available for flying the lateral path and
three modes, [Integrated Approach Navigation (G/P), VNAV, and Vertical Speed]
for flying the vertical path of a Non ILS Approach. The type of approach and
conditions related to the particular approach (No GP, Step down Constraints, RNP,
etc.) may dictate the use of one mode over another. Refer to the Non-ILS
Approach Table in this section for recommended or in some cases mandatory
approach modes (roll and pitch), and associated minima.
Note: Refer to the Supplementary Procedures, Automatic Flight Section,
Instrument Approaches Using IAN, Instrument Procedures Using VNAV,
and Instrument Approaches Using Vertical Speed procedures for
additional information.
Raw Data Monitoring
When conducting any localizer based approach, select the appropriate localizer
frequency and monitor raw data throughout the approach. For all other types of
approaches, raw data must be monitored if the VOR/LOC or HDG SEL roll modes
are used or if the approach is not in the FMC database.
When conducting non-localizer based approaches using IAN (FAC) or LNAV as
the roll mode, monitoring the raw data of the underlying navaid is optional, but
recommended. If IAN or LNAV is used, crews are authorized to conduct VOR,
VOR-DME, or NDB approaches even when the underlying navaid is NOTAM’d
out of service or unavailable. For IAN approaches however, both NAV radios must
be tuned to a VOR frequency (non-localizer frequency).
For non-localizer based approaches, if being vectored to final approach and LNAV
will be the roll mode, the aircraft may be considered established on the approach
when:
• the aircraft reference symbol is touching a published segment of the
extended final approach (5NM Map scale), or
• the aircraft is within the XTK error limit defined by the approach RNP
value.

737NG Operations Manual
RNAV Approaches: RNAV(GPS), RNAV(RNP)
In addition to the Non-ILS Approach Considerations, crews should be familiar
with the additional procedural guidance associated with RNAV operations
including RNAV (GPS) and RNAV (RNP) approaches. Refer to the FCTM
General Information Section, RNAV Operations and the information below for
additional information.
• WAAS: Delta's 737 fleet does not have WAAS (Wide Area Augmentation
System) receivers. Crews will disregard WAAS frequencies and
associated LPV minimums included on some approach plates.
• GPS NOTAMS: Flight plans may include GPS "unreliable" or GPS
"unusable" NOTAMS. With operable GPS(s), regardless of NOTAMS,
crews are legal to conduct any published RNAV (GPS) or RNAV (RNP)
approach if ANP is less than RNP.
• Temperature Restrictions: The 737 FMC is an uncompensated
BARO-VNAV system as it does not correct FMC altitudes for large
temperature deviations. Therefore, crews must comply with both high and
low temperature restrictions listed in the Jeppesen briefing strip. Do not
confuse these temperature restrictions with cold weather temperature
correction requirements.
• Ships 3701-3771: Comply with Category D speed criteria and weather
minima during the final approach segment for all RNAV (RNP)
approaches unless an exception is annotated on the applicable airport
green page.
• Integrated Approach Navigation (IAN) is not authorized for RNAV
(RNP) approaches.
• Due to the precise tracking required during RNAV (RNP) approaches, use
of the autopilot is mandatory from the IAF inbound when in IMC, or
whenever a segment of the approach features an RF leg, until a suitable
visual reference is established. In all other circumstances, use of the
autopilot is highly recommended.
• VOR and DME position updating must be inhibited prior to conducting a
RNAV (RNP) approach. Refer to Supplementary Procedures, Flight
Management, Navigation, Inhibiting VOR/DME Use for Position
Updating.
• RNAV (RNP) approaches require verification that both GPS's are
providing updates to the FMC prior to conducting the approach. Refer to

Non-ILS Approach Summary
For amplified procedures and additional information, refer to Supplementary
Procedures, Automatic Flight, Instrument Approach Using IAN, Instrument
Approach Using VNAV, and Instrument Approach Using Vertical Speed.
All Non-ILS Approaches
• Select approach from FMC database; confirm waypoints and altitude
constraints
• Note presence of glide path on the FMC LEGS page
• Refer to Non-ILS Approach table for minima, and recommended pitch
and roll mode guidance
• No later than FAF [IAF for RNAV (RNP)], one pilot will set Flight and
Nav displays to monitor lateral and vertical deviation as required in the
appropriate approach procedure.
RNAV (RNP), RNAV (GPS), GPS, VOR or NDB Approach: LNAV or FAC
as Roll Mode
• For inoperative equipment, refer to the RNAV Equipment Requirements
chart in Volume 1, Normal Procedures, Introduction section
• Consider missed approach criteria annotated as (LNAV or LNAV/FAC)
listed in Supplementary Procedures, Automatic Flight, for Instrument
Approaches Using IAN, VNAV, and Vertical Speed.
RNAV (RNP) or RNAV (GPS) Approaches or any Approach Using IAN
Mode
• Verify OAT and temperature restriction compliance.
RNAV (RNP) Approach
• Prior to IAF, verify or enter RNP value as required on FMC LEGS page.
• VOR and DME Update - Inhibit (FMC NAV Options, page 2)
• Verify both GPS’s are updating by selecting FMC NAV STATUS (page 1)
and verifying the “(2)” is present next to the GPS reference.
• Use of the autopilot is mandatory from the IAF inbound when in IMC, or
whenever a segment of the approach features an RF Leg, until a suitable
visual reference is established.
• Brief Missed approach plan if approach is discontinued during an RF leg.
• Confirm LNAV activation or reselect LNAV and verify active
waypoint
• Confirm engagement of or reselect autopilot
• Until alternate ATC instruction is received, continue to fly approach
track to the MAP and transition to the published Missed Approach
procedure.

Circling Approach
Weather Requirements
Use the higher of:
• Circle to land category D or the highest maximum speed published
minima, or
• 1,000 feet (300m) ceiling or HAA if higher, and 3 statute miles (4,800m)
visibility.
Minimum Descent Altitude MDA(H)
Use the higher of:
• Published MDA(H) or
• Airport elevation plus 1,000 feet (300m).
General Considerations
• Use autopilot, autothrottles, and flight director if available to reduce
workload during the circling maneuver
• Set established MDA(H) in the MCP altitude window
• Use approach procedures appropriate for the type of approach used to
descend to the MDA(H).
• If using an ILS approach, or a non-ILS approach with glideslope, do
not select APP mode, as it will not capture and level off at the
MDA(H). Use VNAV or V/S mode to control descent.
• Recommended configuration for descent to MDA(H) is gear down, flaps
15 with two engines operating, or gear up, flaps 5 or 10 with one engine
inoperative. Complete the configuration when level at MDA(H) prior to
descending below 1,000 feet AGL.
• Do not descend below the established MDA(H) until abeam the landing
runway and intercepting the normal visual descent profile.
• Disengage the autopilot no later than 50 feet below MDA(H).
CAUTION: Circle in the direction assigned in the approach clearance, or in
accordance with procedures in the airway manual. Circle to
avoid all obstacles and other hazards.

FMS Utilization
• Using FMS while maneuvering to land is optional
• Select appropriate approach from the database
• If desired, enter the airport reference (e.g., KATL) point on the fix page
and enter a range circle to improve situational awareness in the
maneuvering phase. (a 3.5 mile arc will approximate 2.5 to 3 miles from
the end of the runways).
• Prior to commencing the approach, if desired, select the landing runway,
line select it to 1L on the LEGS page, making it the active way point, and
extend the centerline to provide guidance for maneuvering to land. Do not
execute the LEGS page modification until abeam the landing runway.
Doing so will delete the programed missed approach procedure. Upon
execution, VNAV path information will be available from present position
to the landing runway.
Missed Approach - Circling Approach
• Execute a missed approach anytime the airport is no longer in sight.
• If not stabilized on final approach by 500 feet AGL, initiate a go-around.
• Make a climbing turn toward the landing runway to reach the missed
approach heading, even if it requires a turn of more than 180 degrees and
not in the shortest direction.
• Maintain the missed approach flap setting until close in maneuvering is
complete.
Visual Approach and Landing Considerations
FMS/ND Utilization
• Using the FMS during visual approaches is optional
• Program the landing runway as the active Waypoints
• With ND in 10 mile scale, turn base leg from downwind leg when the
aircraft symbol is approximately 3 - 4 nautical miles from the approach
end of runway
• Use VNAV path information, if available, or distance remaining from
runway and height above touchdown zone elevation (TDZE) to determine
3 to 1 descent profile.

Pre-Departure Clearance
The flight crew shall compare the filed flight plan versus the digital pre-departure
clearance and shall initiate voice contact with Air Traffic Control if any
question/confusion exists between the filed flight plan and the digital
pre-departure clearance.
Digital-Automatic Information Service
The flight crew shall verify that the D-ATIS altimeter setting numeric value and
alpha value are identical. The alpha value is the numeric altimeter setting spelled
out (i.e., two niner niner two). This will be depicted on the ACARS ATIS message.
If the D-ATIS altimeter setting altimeter numeric value and alpha values are
different, the flight crew must not accept the D-ATIS altimeter setting.
Company Communications Sequence
The COMMUNICATIONS SEQUENCE chart depicts DATA LINK functions
that are currently in effect for Delta Air Lines. The chronological sequence in
which DATA LINK messages should be sent is shown as a function of flight
phase. The messages that appear above the profile are ROUTINE and should be
sent whenever appropriate on every flight. The messages below the profile are
NON ROUTINE and should be sent as needed.
Messages are delivered to the Flight Control dispatcher’s cue and are also directly
processed by Flight Following. This direct processing of DATA LINK messages
results in system wide updates in our host computers.

consistent for all messages. With some experimentation and use, it will become
simple to use each feature.
Ground support for some ACARS functions is still in development and therefore
these functions should not be used. Refer to the DATA LINK INDEX menu tree
on the next page for operational functions. If in doubt about the status of an

RNAV (RNP) Approach Verification (ACARS Reporting)
Delta maintains an agreement with the FAA which requires on-going data
collection on the success of RNAV (RNP) operations. The primary means of
approach verification is through an ACARS downlink to the address of
“ATLWDDL” (ACARS B ENROUTE B DOWNLINKS B OTHER). Enter
the airport, approach flown and “SAT” or “UNSAT”. Please include the specific
reason for any approach considered “UNSAT”.
Crews may also verify approaches flown and provide more detailed feedback via
the “RNAV SID, STAR, and RNP Feedback” link located in the Pilot Feedback
and Reporting section of the Flight Ops web page.
Service Failure During Flight
If a service failure was reported during the flight or the service failure was
accepted prior to pushback, refer to “Other” in this section for information
on how to submit the report.
Arrival Delays
For any arrival delays, refer to “Other” in this section for information on
how to submit the report.

Weather Radar Operation
The recommended tilt and range settings are guidelines for good radar
operation. The flight crew is not limited to these settings. Operational
needs often dictate flexibility in tilt and range selections.
Before Takeoff
Confirm RADAR operation with a confidence check.
Set tilt 15° UP, WX mode, and short range.
Slowly lower tilt until weather or ground returns are displayed.
If no returns can be detected, suspect an inoperative radar.
WARNING:Do not operate weather radar in a hangar or within 50
feet of any personnel or a fuel spill.
To evaluate terminal area weather before takeoff:
Set tilt at 15° UP, RANGE at 40 nm or less.
The radar height of weather targets displayed is at least
(Tilt x Distance x 100). Weather targets displayed at:
10 nm
15 nm
20 nm
are at least 15,000 feet AGL
are at least 22,500 feet AGL
are at least 30,000 feet AGL
Slowly lower tilt from 15° UP to 5° UP while evaluating weather
returns in the area.
Takeoff
During takeoff, tilt is initially set at 5° UP, with range at shortest
appropriate for terminal area conditions.
During initial climb (below 10,000 feet AGL) set the tilt between 2° to 7°
UP, with 5° tilt being a good compromise. (Maintain the radar display clear
of ground returns while allowing weather returns to be displayed).
Climb
As climb continues above 10,000 feet AGL, lower tilt as necessary to
maintain ground returns at the outer edge of the display.
A range selection of 80 nm or less is optimal during climb, unless a longer
range setting is needed for deviation planning.

Continued from previous page
Cruise
To establish enroute park:
Set RANGE at 80 nm or less.
Adjust tilt to produce ground returns at the outer edge of radar display.
This tilt setting guards against over scanning nearby weather areas
and provides continuous confirmation that the radar is working.
Weather targets will separate from ground returns and move toward
the bottom of the display.
Range settings above 100 nm should be selected occasionally for
long-range planning.
Set tilt to produce a scattering of ground returns beyond 100 nm.
Storms detected at long range will increase in displayed intensity as
they are approached. Plan early deviations accordingly.
Note: Nearby weather areas may not be detected due to over scanning.
When returning to a shorter range, lower tilt to enroute park
position.
At cruise altitudes above 30,000 feet:
Use sufficient down tilt to direct the beam into unfrozen areas of nearby
storms.

Descent
On descent from cruise altitude, raise tilt as necessary to maintain ground
returns at the outer edge of the display.
Low Altitude Park
Generally used at altitudes below 10,000 feet AGL.
To observe weather:
Set tilt 2° to 5° UP, range at shortest appropriate distance.
Note: If ground returns flood display, raise tilt until ground returns are
removed, and weather can be displayed.
Approach
Approach Park
On final approach:
Set tilt at 10° UP, range at 20 nm.
At 10° UP tilt the radar height of weather returns displayed will be
above aircraft altitude by at least (Tilt x Distance x 100). Weather
areas will be developed above aircraft altitude by at least:
10 nm
15 nm
20 nm
10,000 ft.
15,000 ft.
20,000 ft
Strong returns at mid to upper levels indicates hazardous convective
activity.
In a thunderstorm environment, occasionally lower tilt to produce
ground returns and detect radar shadows, then return tilt to approach
park.

Fuel Load Distribution
Main tanks No. 1 and No. 2 should normally be serviced equally until full.
Additional fuel is loaded into the center tank until the desired fuel load is reached.
Note: Main tanks No. 1 and No. 2 must be scheduled to be full if the center
tank contains more than 1,000 lbs of fuel.
Note: If the main tanks are not full, the zero fuel gross weight of the
airplane, plus the weight of the center tank fuel, may exceed the
maximum zero fuel gross weight by up to 5,000 pounds for takeoff,
climb, and cruise; and up to 3,000 pounds for descent and landing,
provided the effects of balance (CG) have been considered.
Fuel Pressure
Apply from a truck or fuel pit. A nozzle pressure of 50 psi provides approximately
300 U.S. gallons per minute.
Normal Refueling
When a full fuel load is required, the fuel shutoff system closes the fueling valves
automatically when the tanks are full. When a partial fuel load is required, the fuel
quantity indicators are monitored and the fueling valves are closed by manually
positioning the fueling valve switches to CLOSED when the desired fuel quantity
is aboard the airplane.

Releasing the override button allows the spring in the valve
to close the valve.
Caution must be observed not to overfill a tank, since there is no
automatic fuel shutoff during manual operation. When the desired
amount of fuel has been pumped into the tanks, the refueling valves for
the respective tanks can be released.
Ground Transfer of Fuel
Fuel can be transferred from one tank to another tank by using the appropriate fuel
pumps, the fueling valve, the defueling valve, and the crossfeed valve. AC power
must be available.
Prior to transferring fuel or defueling, conduct a lamp test of the respective fuel
pump LOW PRESSURE lights. When transferring fuel or defueling from either
the center or main wing tanks, montior the fuel pump LOW PRESSURE lights and
turn the fuel pumps OFF at the first indication of fuel pump low pressure.
Fuel may be transferred from tank to tank or the aircraft may be defueled with
passengers on board, provided the fuel quantity in the tank from which fuel is
being taken is maintained at not less than 2000 pounds. Deplane all passengers and
non-essential crew when defueling or transferring fuel from a tank that has less

Supplementary Procedures-Adverse Weather
Introduction
Airplane operation in adverse weather conditions may require additional
considerations due to the effects of extreme temperatures, precipitation,
turbulence, and windshear. Procedures in this section supplement normal
procedures and should be observed when applicable.
Cold Weather Operation
Considerations associated with cold weather operation are primarily concerned
with low temperatures and with ice and snow on the airplane, ramps, taxiways and
runways.
Icing conditions exist when OAT is 10°C (50°F) or below during ground
operations, takeoff, initial climb or go-around; or, TAT is 10°C or below in-flight
and:
• visible moisture (clouds, fog with visibility less than one mile, rain, snow,
ice crystals, or other freezing precipitation) is present, or
• standing water, ice, or snow is present on the ramps, taxiways, or
runways.
Preflight
Although removal of surface snow, ice or frost is normally an ACS function, the
flight crew should use additional care and scrutiny during preflight preparation to
inspect areas where surface snow or frost could change or affect normal system
operations.
Exterior Inspection
Surfaces.......................................................................................... Check
Check for frost, snow or ice.
Thin hoarfrost is acceptable on the upper surface of the fuselage provided
all vents and ports are clear. Thin hoarfrost is a uniform white deposit of
fine crystalline texture, which usually occurs on exposed surfaces on a cold
and cloudless night, and which is thin enough to distinguish surface
features underneath, such as paint lines, markings or lettering.
When cold-soaked fuel frost is present, refer to Supplementary Procedures,
Anti-Ice, Rain Section, SP.3.
Control surfaces ............................................................................. Check
Verify control surfaces are free of snow or ice.

Control balance cavities ................................................................. Check
Check drainage after snow removal. Puddled water may refreeze in flight.
Pitot probes and static ports ........................................................... Check
Check all pitot probes and static ports free of ice and snow. Water rundown
after snow removal may refreeze immediately forward of static ports and
cause an ice buildup which disturbs airflow over the static ports resulting
in erroneous static readings even when static ports themselves are clear.
Air conditioning inlets and exits .................................................... Check
Verify that the air inlets and exits, including the outflow valve, are free of
snow and ice.
If the APU is operating, verify that the outflow valve is fully open.
Engine inlets ................................................................................... Check
Verify that the inlet cowling is free of snow and ice.
Verify that the fan blades are free of snow and ice and that the fan is free

Fuel tank vents ............................................................................... Check
Verify all traces of ice and frost are removed.
Landing gear doors ......................................................................... Check
Landing gear doors should be free of snow or ice.
APU air inlets ................................................................................ Check
The APU inlet door and cooling air inlet must be free of snow or ice prior
to APU start.

Engine Start
Note: If airframe icing conditions exist or taxiways are slippery,
delayed engine start is not recommended. Normal procedures
are applicable with some exceptions.
Do the normal Engine Start Procedure with the following modifications:
• If the engine has been cold soaked for one or more hours at
ambient temperatures below -40°C, do not start or motor the
engine. Maintenance personnel should do appropriate procedures
for adverse weather heating of the Hydro-Mechanical Unit.
• If the engine has been cold soaked for three or more hours at
ambient temperatures below -40°C, do not start or motor the
engine. Maintenance personnel should do appropriate procedures
for adverse weather starter servicing.
• If ambient temperature is below -35°C, idle the engine for two
minutes before changing thrust lever position.
• Up to three and one–half minutes may be allowed for oil pressure
to reach the minimum operating pressure. During this period, the
LOW OIL PRESSURE light may remain illuminated, pressure
may go above the normal range and the FILTER BYPASS light
may illuminate. Operate the engine at idle thrust until oil pressure
returns to the normal range.
• Display units may require additional warm-up time before
displayed engine indications accurately show changing values.
Display units may appear less bright than normal.
Note: If a precautionary shutdown was accomplished due to lack of
oil pressure after start, the engine heat generated may provide
adequate warming for a subsequent start to be successful (allow
10 to 15 minutes for internal heat distribution to warm the oil
system). If available, a hot air source may be used to warm the
oil tank and engine gearbox prior to the next start.
After Start

Engine Anti-ice Operation - On the Ground
Engine anti-ice must be selected ON immediately after both engines are started
and remain on during all ground operations when icing conditions exist or are
anticipated, except when the temperature is below -40°C OAT.
WARNING: Do not rely on airframe visual icing cues before
activating engine anti-ice. Use the temperature and
visible moisture criteria because late activation of
engine anti-ice may allow excessive ingestion of ice
and result in engine damage or failure.
CAUTION: Do not use engine anti-ice when OAT is above 10°C.

Use wing anti-ice during all ground operations between engine start and takeoff
when icing conditions exist or are anticipated, unless the airplane is, or will be
protected by the application of Type II or Type IV fluid in compliance with Delta’s
de-icing program.
WARNING: Do not use wing anti-ice as an alternative for ground
de-icing/anti-icing. Close inspection is still needed to
ensure that no frost, snow or ice is adhering to the
wing, leading edge devices, stabilizer, control
surfaces or other critical airplane components at
takeoff.
WARNING: Ground use of the wing anti–ice system is intended to
complement, and not replace, ground
de–icing/anti–icing and inspection procedures.
CAUTION: Do not use wing anti-ice when OAT is above 10°C.
When wing anti-ice is needed:
WING ANTI-ICE switch .............................................................. ON
Verify that the L and R VALVE OPEN lights illuminate bright,

Taxi–Out
CAUTION: Taxi at a reduced speed. Use smaller nose wheel
steering and rudder inputs and apply minimum
thrust evenly and smoothly. Taxiing on slippery
taxiways or runways at excessive speed or with high
crosswinds may start a skid.
CAUTION: When operating the engines over significant amounts
of standing de-icing or anti-icing fluid, limit thrust to
the minimum required. Excessive ingestion of de-icing
or anti-icing fluid can cause the fluid to build up on
the engine compressor blades resulting in compressor
stalls and engine surges.
When engine anti-ice is required and the OAT is 3°C or below, do an
engine run up, as needed, to minimize ice build-up. Use the following
procedure:
Check that the area behind the airplane is clear.
Run-up to a minimum of 70% N1 for approximately 30 seconds
duration at intervals no greater than 30 minutes.
If airport surface conditions and the concentration of aircraft do not
permit the engine thrust level to be increased to 70% N1, then set a
thrust level and time at that thrust level as high as practical.
Note: When operating in conditions of freezing rain, freezing drizzle,
freezing fog or heavy snow, run-ups to a minimum of 70% N1
for approximately 1 second duration at intervals no greater then
10 minutes enhance ice shedding.
Flight controls ................................................................................ Check
Note: Increase in control forces can be expected at low temperatures
because of increased resistance in cables and thickened oil in
snubbers and bearings.
If any flight control is suspected of binding or restricted movement,
refer to the Supplementary Flight Controls section, Flight Controls

minimize steering lag caused by low temperatures.
Flaps .............................................................................................. Check
Move flaps through full travel to ensure freedom of movement.
CAUTION: The flap position indicator and leading edge
devices annunciator panel should be closely

in the same position as indicated.
Flaps ......................................................................... Set flaps, as needed
If taxi route is through slush or standing water in low temperatures or
if precipitation is falling with temperatures below freezing, taxi with
flaps up. Taxiing with flaps extended subjects the flaps and flap
drives to snow and slush accumulations from the main gear wheels.
Leading edge devices are also susceptible to slush accumulations.
If flaps are up for taxi, delay accomplishment of the TAXI and
BEFORE TAKEOFF checklists until flaps are properly positioned
and a flap movement check completed.
Exposure of untreated surfaces for the short period of time from
delayed flap extension to takeoff should not affect the performance of
the wing nor jeopardize compliance with the clean aircraft concept.
If thrust reversers are used on snow or slush covered taxiways, the
aircraft (especially wing leading edges) must be reinspected for
contamination.

Before Takeoff
CAUTION: To prevent damage to the retractable landing lights,
consider leaving them in the retracted position when
taking off on contaminated runways.
Flaps ..........................................................................................Verify set
Takeoff Speeds
Takeoff, accelerate-stop distances and V1 speeds are normally based
on smooth, dry, hard-surfaced runways. Snow, slush, standing water
and ice affect takeoff performance. Slush and standing water affect
acceleration, and precipitation in any form affects stopping capability.
For performance corrections, see ODM/ARM.
Anti-ice Takeoff Performance Penalties
When takeoff performance is based on known or forecast icing
conditions at departure time and performance corrections are
required, they will be applied to the weight and balance data
(AWABS). This will be indicated by a statement printed on AWABS
below the adjusted takeoff weight and in the performance notes.
The flight crew is responsible for applying takeoff weight corrections
when conditions require and the Weight Data Record does not
indicate that corrections were applied.
WARNING: The Captain must verify that there is no
contamination (snow, ice or frost) adhering to the
wings or control surfaces.
It can be reasonably assumed that those areas not visible are clear if
the entire airplane has been deiced, the wing surfaces are viewed from
the cabin are clear of accumulation and a satisfactory control check is
made just prior to takeoff. If contamination is suspected, particularly
if lengthy delays occur, return aircraft to ACS/Maintenance for
inspection and further deicing if necessary.

Avoid fast rotation rates (in excess of 3 degrees/second) since
combined with wing contamination this may result in reduction of
stall margin. At light gross weights and cold temperatures, a 3 degree
per second rotation rate will result in an initial climb speed above V2
+20. Initial climb speeds up to V2 +25 will not significantly affect the
climb profile.
At designated high elevation airports, improved performance takeoffs
can be used if needed to increase the climb limit weights for takeoff
performance. This will provide additional stall margins with
minimum performance penalties.
Rejected Takeoff
If operable, use RTO position of the AUTOBRAKE selector for
takeoff. When aborting a takeoff on a slippery runway, use maximum
allowable symmetrical reverse thrust and ensure speed brake lever is
up. If a side slip develops, correct back to center line by reducing
reverse thrust to reverse idle and releasing brakes. This allows the tire
cornering forces to be used for alignment to runway center line. Use
rudder, steering and differential braking, as required, to prevent over
correcting past the center line. When reestablished on center line,
apply maximum braking and reverse thrust to stop the aircraft.
Takeoff
Refer to the Guidelines for Contaminated Runways procedure in this
section, if applicable.
Do the normal Takeoff Procedure with the following modification:
When engine anti-ice is required and the OAT is 3°C or below, the takeoff
must be preceded by a static engine run-up. Use the following procedure:
Run-up to a minimum of 70% N1 and confirm stable engine

When operating in areas of possible icing, activate engine anti–ice before entering
icing conditions.
WARNING: Do not rely on airframe visual icing cues before
activating engine anti–ice. Use the temperature and

Wing Anti-Ice Operation – In Flight
Note: Do not use wing anti-ice prior to 400 feet AGL.
Ice accumulation on the flight deck window frames, windshield center post, or on
the windshield wiper arm may be used as an indication of structural icing
conditions and the need to turn on wing anti-ice.
The wing anti-ice system may be used as a de-icer or anti-icer in flight only. The
primary method is to use it as a de-icer by allowing ice to accumulate before
turning wing anti-ice on. This procedure provides the cleanest airfoil surface, the
least possible runback ice formation, and the least thrust and fuel penalty.
Normally it is not necessary to shed ice periodically unless extended flight through
icing conditions is necessary (holding).
The secondary method is to use wing anti-ice before ice accumulation. Operate the
wing anti-ice system as an anti-icer only during extended operations in moderate
or severe icing conditions, such as holding.
CAUTION: Do not use wing anti-ice when TAT is above 10°C.
CAUTION: Use of wing anti-ice above approximately FL350 may
cause bleed trip off and possible loss of cabin
pressure.
Note: Prolonged operation in icing conditions with the leading edge
and trailing edge flaps extended is not recommended. Holding
in icing conditions with flaps extended is prohibited.

Ground De/Anti-Icing
Definitions and Concepts
Ground de/anti-icing background information and policies are described in
this section and the Airway Manual, Weather - Icing. Procedures for
aircraft specific de/anti-icing are located in this section.
Deicing
Deicing is the procedure of removing frost, ice, slush, or snow from the
aircraft in order to provide clean surfaces. On the ground this may be
accomplished by:
• Using any mechanical or pneumatic means that will not damage the
aircraft.
• Using heated deicing fluid to remove all forms of frozen
contamination (including environmental frost). Heated fluids
penetrate the frozen contaminants and contact the aircraft skin. The
high thermal conductivity of the aircraft skin causes the heat to
spread, breaking the bond of the ice and snow, causing it to melt or
fall off the aircraft.
Anti-icing
Anti-icing is a precautionary procedure that provides protection against the
formation of frost or ice, and accumulation of snow or slush on treated
surfaces of the aircraft for a limited period of time (holdover time).
Anti-icing fluid is the only protection against airfoil icing prior to getting
airborne. Therefore, fluid application should be completed as close to
takeoff time as possible.
De/Anti-icing
A combination of the deicing and anti-icing procedures.
Secondary De/Anti-icing
If an aircraft which has been de/anti-iced is delayed on the ground long
enough that anti-icing protection is no longer effective, or if for any reason
the de/anti-icing process is interrupted while freezing/frozen precipitation
is falling, the ground de/anti-icing procedure must be reaccomplished in its
entirety. This is referred to as secondary de/anti-icing.
Copyright © Delta Air Lines, Inc. See title page for details.
December 18, 2007
SP.16.19
Supplementary Procedures Adverse Weather
737NG Operations Manual
When secondary de/anti-icing is necessary, the contaminated anti-icing
fluid and all frozen contamination must be completely removed by deicing
before making another application of anti-icing fluid. If a holdover time
was previously established after completing secondary de/anti-icing, a
new holdover time must be determined.
Clean Aircraft Concept
The airline industry, in concert with the FAA, is operating with a clean
aircraft concept to minimize the effects of all forms of frozen
contamination on aircraft surfaces.
Takeoff is prohibited when frost, ice, snow or slush is adhering to the
wings, control surfaces, engine inlets, or other critical surfaces of the
aircraft.
• Do not rely on air flow during takeoff roll to remove frozen
precipitation that may be adhering to the aircraft.
• A coating of frost up to 1/8 inch thick on the lower wing surface,
below the fuel tank area, is permissible provided it is caused by
cold soaked fuel.
• A thin coating of frost is permitted on the fuselage, provided letter
and paint lines are visible through the frost.
Cold soaked wings
A cold soaked wing condition can occur when an aircraft lands with a large
amount of fuel remaining in the wing tanks. During cruise at high altitude,
the aircraft is subjected to extremely cold temperatures for an extended
period of time causing the aircraft skin and fuel to become super cooled. If
enough super cooled fuel is remaining in the wing tanks to contact the
upper wing surface, it will maintain the skin at a temperature below
freezing. When this happens, any moisture contacting the upper wing
surface may form frozen contamination, even in ambient air temperatures
as high as 15°C (60°F).
For all other aircraft, a cold soaked wing should only be suspected if both
of the following conditions are met.
• Frost or ice is observed on the wing’s underside during the walk
around, and
• A large amount of fuel was remaining in the wing tanks after
landing.
Copyright © Delta Air Lines, Inc. See title page for details.
SP.16.20
December 18, 2007
Supplementary Procedures Adverse Weather
737NG Operations Manual
If cold soaked wings are suspected, cabin windows may be used during the
preflight to visually inspect the upper wing surfaces for frost or ice. The
quickest way to alleviate a cold soaked wing condition is to add warm fuel
to the wing tanks.
Critical Aircraft Surfaces
Critical aircraft surfaces are those surfaces which must be clear of adhering
frozen contamination before beginning takeoff roll. Critical aircraft
surfaces include, but may not be limited to:
• Wings, slats, flaps, ailerons, spoilers.
• Horizontal stabilizer and elevator.
• Vertical stabilizer and rudder.
• Pitot heads, static ports, ram-air intakes, engine and flight
instrument probes, other kinds of instrument sensor pickups.
• Engine and APU inlets and exhausts.
• Landing gear and landing gear doors.
• Fuel vents.
• Radome
Representative Aircraft Surfaces
Representative aircraft surfaces are those which the pilot can readily
observe to determine whether or not frost, ice, or snow is accumulating or
forming on that surface. By using a representative surface, a pilot can make
a reasoned judgement regarding whether or not frost, ice, or snow is
adhering to other aircraft surfaces.
Representative aircraft surfaces visible from the flight deck are:
• Fuselage.
• Radome.
Representative aircraft surfaces visible from the best vantage point(s) in
the cabin are:
• Wing area upper surfaces.
• Wing leading edges.
• Engine inlets.

SP.16.21
Supplementary Procedures Adverse Weather
737NG Operations Manual
Best Vantage Point(s)
The best vantage point is the location in the aircraft where a pilot can best
check representative aircraft surfaces. This will normally be a passenger
window in the over-wing area. It may be necessary in some circumstances
to move forward a few rows to get the best view of the engines. Outside
lighting conditions and glare may also affect which specific location is the
best vantage point.
Holdover Time
Holdover time is the estimated time that anti-icing fluid will prevent the
formation of frozen contaminants on the treated surfaces of the aircraft.
Holdover time is determined by the pilot using the Holdover Time Tables.
Holdover time starts when the final application of fluid begins. The final
fluid applied will be either:
• De/Anti-icing fluid in the one step procedure, or
• Anti-icing fluid in the two step procedure.
Holdover time ends when either:
• The applied fluid loses its effectiveness, or
• The time extracted from the holdover time range expires.
Ground Icing Conditions
Guidance for determining precipitation categories (type) and intensities
(light, moderate, and heavy) is located in the Airway Manual, Weather,
Hazardous Weather - Icing.
WARNING: Do not take off during hail, moderate or heavy
freezing rain, snow pellets, or heavy ice pellets.
Operational Effects of Frozen Contamination
Frost, ice, and/or snow adhering to airfoils, engine inlets, flight controls
and flight instrument sensors, even in small amounts, can have a critical
effect on aircraft performance. For example, ice formations on the wing’s
leading edges and upper surfaces creating texture roughness of medium to
coarse sandpaper can reduce lift as much as 30 percent and increase drag
by 40 percent. Therefore, frozen contamination on the aircraft in any form
poses a serious threat to flight safety due to degraded operational
performance.

Supplementary Procedures Adverse Weather
737NG Operations Manual
Degraded aerodynamic performance such as:
• Lift decreases - Frozen contamination may destroy the lifting
ability of an airfoil, including leading edge devices. The aircraft
may not lift off at a normal pitch attitude. Required gaps in leading
edge devices may be blocked and further reduce lift on one or both
wings.
• Drag/weight increases - An aircraft may fail to reach takeoff speed
in the calculated distance.
• Stall speed increases - Buffet or stall may occur before activation
of stall warning systems.
• Controllability decreases - Caused by changing the aerodynamic
properties of the control surface due to ice. For example, ice on the
leading edge of the horizontal stabilizer can affect pitch control,
especially during rotation.
Reduction in available engine power caused by:
• Icing of engine inlets, guide vanes or compressor blades.
• Ingestion of ice shedding from other parts of the aircraft.
Impairment of flight and engine performance indicators resulting in:
• Incorrect power settings due to EPR probe icing.
• Incorrect airspeed indication caused by pitot/static probe icing.
• Erroneous stall warning caused by ice on the AOA probe.
Degraded flight control response as ice may interfere with the free
movement of the flight controls.
Delta De/Anti-icing Program
Delta Air Lines’ Ground De/Anti-icing Program is coordinated among
Airport Customer Service, Maintenance, Flight Control, Flight
Operations, Fleet Management and Reliability, and Flight Safety. Each
Delta deicing station will have designated trained personnel on duty to
determine when to initiate ground de/anti-icing operations. At airports
where no Delta personnel are permanently assigned, the Captain may
declare the de/anti-icing program in effect. In this case, the Captain shares
responsibility for the effectiveness of the effort with the ground crew. The
procedures outlined in this section will help guide the Captain through this
decision making process.
There are several components to Delta’s De/Anti-icing Program. Pilots
need to be aware of how key components play an integral part in ensuring
safe winter flight operations.

De/Anti-icing Alert Plan
A Deicing Alert Chart will be issued daily by Delta Meteorology to the
OCC Duty Director. This chart reflects forecasted freezing/frozen
precipitation for specific geographic regions for the next day’s flying (24 48 hours in advance). Affected stations will be notified, and plans will be
made to initiate local de/anti-icing operations. Flight Control will work in
conjunction with individual stations to determine possible changes to the
flight schedule based on any anticipated decrease in airport air traffic
capacity.
Station De/Anti-icing Plans
Each Delta station that conducts de/anti-icing operations is required to
have a detailed de/anti-icing plan on file. This plan contains, but is not
limited to the following information:
• Persons responsible for implementing/terminating the de/anti-icing
plan.
• Deicing equipment and fluids.
• Location of de/anti-icing areas.
• Local procedures including communication with the flight crew
and coordination with local ATC.
ATC will be notified whenever the local de/anti-icing plan is in effect.
Departure runway queues will be managed by ATC in order to minimize
the amount of time an aircraft spends on the ground after being
de/anti-iced.
Special procedures for the pilots will be contained in the Airway Manual,
10-0 Delta Special Pages (green pages), or noted in the Airport Remarks
section of the flight plan.
Responsibility for De/Anti-icing of Aircraft
The Captain has the ultimate responsibility for ensuring the aircraft’s
critical surfaces are free of frozen contamination and the flight can be
operated safely. The ground deicing crew shares in this responsibility by
providing an aircraft that complies with the clean aircraft concept.
Normally, aircraft de/anti-icing will be performed by:
• Delta Maintenance.
• Airport Customer Service (ACS).
• Business partner (contractor).
• Any combination of the above.

737NG Operations Manual
ACS and/or contractors accomplish the majority of aircraft de/anti-icing.
As always, pilot vigilance is paramount during any de/anti-icing
procedure. If possible, the pilots should evaluate the operation from the
flight deck as it is being conducted and:
• If deicing or anti-icing is not being performed properly and safety
is jeopardized, stop the operation and attempt to have the problem
corrected.
• When possible, provide timely feedback on individual station
de/anti-icing performance to the Dispatcher. A telephone report is
preferred.
• Document all de/anti-icing problems or kudos on a COR.
Depending on the circumstances and local station procedures, aircraft
de/anti-icing may be accomplished:
• Whenever requested by the Captain.
• Prior to taxiing into the gate (to prevent accumulation).
• During overnight parking (prior to pilots’ arrival).
• At the gate - prior to pushback.
• After pushback - clear of the gate.
• During taxi operations, i.e., car wash.
Deicing at Offline Stations
If de/anti-icing is required at an offline station, consult with Flight Control.
In unusual circumstances, such as when operating at an offline station, the
pilots may be required to supervise the de/anti-icing operation. In this case,
the pilots must ensure the aircraft is free of frozen contamination in
accordance with the clean aircraft concept. If the Captain determines that
the pilots are unable to effectively supervise the de/anti-icing procedure,
the flight will not operate.
Note: Contact the Dispatcher if a noncertified fluid must be used.

De/Anti-icing Fluids
Type I Fluid
Type I fluid is a deicing and anti-icing fluid with low viscosity and is
considered an unthickened fluid. It forms a very thin wetting film on
aircraft surfaces and has excellent deicing properties. Type I fluid can be
orange-colored or colorless. Due to its low viscosity, it provides minimal
anti-icing protection. Type I fluid is always diluted because adding water
ensures fluid freeze point protection and ensures proper aerodynamic
flow-off characteristics. Type I fluid is never applied 100 percent.
Different dilution ratios of Type I fluids affect the freeze point of the fluid,
but do not alter its holdover time significantly. Consequently, there are no
ratio break outs on the Type I Holdover Time Table. The Type I Holdover
Table will apply when this fluid is used.
Type II Fluid
Type II fluid is a deicing and anti-icing fluid of high viscosity and is
considered a thickened fluid. It adheres to the aircraft surfaces to provide
a protective film. It creates a thicker layer than Type I fluid and thus has
improved anti-icing capability. Type II fluid can be straw-colored or
colorless. Airflow during takeoff roll causes the fluid to shed so that by
rotation the surfaces are aerodynamically clean. Varying concentration
levels of Type II fluid affect its holdover time. Delta prefers to use 100
percent concentration of Type II fluid, but other concentration levels may
be used at contract or overseas facilities. Not all stations will have Type II
available. The Type II Holdover Table will apply when this fluid is used.
Type III Fluid
Type III fluid is a deicing and anti-icing fluid with longer [holdover] times
than Type I fluid, but lower viscosity than Type IV fluids. It was primarily
designed for use on aircraft with slower rotation speeds to ease shedding
of the fluid during takeoff, but it is fully approved for use on Delta aircraft.
Type III fluid is bright yellow in color. Few stations are expected to have
Type III fluid available. The Type III Holdover Table will apply when this
fluid is used.
Type III fluid or fluid/water mixtures are normally applied heated when

Type IV Fluid
Type IV fluid is an enhanced performance deicing and anti-icing fluid with
characteristics similar to Type II. Type IV fluid is green colored, except in
Japan, where it is colorless. Its anti-icing effectiveness is superior to Type
II fluid and holdover time is increased by a significant factor under most
conditions. There is a separate Holdover Time Table for Type IV which
reflects this improved performance. Additionally, Type IV fluid has some
unique visual characteristics. It is pale green in color and considerably
thicker than Type II fluid. When applied to the wings, the extra thickness
may cause the fluid to appear wavy or bumpy. Varying concentration levels
of Type IV fluid affect its holdover time. Delta prefers to use 100 percent
concentration of Type IV, but other concentration levels may be used at
contract or overseas facilities. Not all stations will have Type IV available.
The Type IV Holdover Table will apply when this fluid is used.
Some contract deicing ground crews may communicate a specific brand of
Type IV fluid during the Post De/Anti-icing Report, for example, “Type IV,
Octagon, Max-Flight.” Flight crews should disregard the fluid brand
information and utilize the Type IV Holdover Time Table.
Noncertified Fluids
A de/anti-icing fluid that does not meet SAE/ISO certification
requirements (including military fluids) is classified as noncertified, Type
I, Type II, Type III, or Type IV fluid. These fluids may be encountered at
certain international stations, or during offline operations at military bases.
The use of noncertified Type I fluid is not authorized for takeoff during
active icing conditions. Contact the Dispatcher if a noncertified Type I
fluid is used. Noncertified Type II, Type III, or Type IV fluids are not
authorized under any circumstances.
Fluid Standards
Deicing fluids are:
• Heated water when OAT is above or equal to -3°C (27°F).
• Heated water mixed with Type I fluid.
• Heated water mixed with one of the following SAE/ISO fluids:
• Type II, or
• Type III, or
• Type IV.

SP.16.27
Supplementary Procedures Adverse Weather
737NG Operations Manual
Anti-icing fluids must be certified by the:
• Society of Automotive Engineers (SAE).
• International Standards Organization (ISO).
Anti-icing fluids are:
• Heated or unheated water mixed with one of the following
SAE/ISO fluids:
• Type I,
• Type II,
• Type III, or
• Type IV.
• Undiluted SAE/ISO Type II fluid.
• Undiluted SAE Type III fluid
• Undiluted SAE/ISO Type IV fluid
All de/anti-icing fluids have a limit to their low operational temperature
use. Ground deicing crews and Dispatchers have access to this information
in the Technical Operations Policies and Procedures (TOPP) 20-30-05.
The following is an approximate low temperature limit of the fluids:
• Type I has the lowest temperature use, approximately -30°C
(-22°F)
• Type II and IV are approximately -25°C (-13°F)
• Type III is approximately -29°C (-20°F)
Under extremely low temperature conditions consider using alternate
means of deicing, such as brooms or nonheated forced air.
Fluid Effects on Braking and Steering
Generally, Type I, Type II, Type III, and Type IV fluids are considered to
have the same affect on braking and steering as water.
CAUTION: A slippery condition may exist in and around the
de/anti-icing ramp and taxi ways, particularly during
dry weather conditions or light precipitation.
De/Anti-icing Fluid vs. Hydraulic Fluid
It is very difficult to distinguish between de/anti-icing fluids and hydraulic
fluid. In small quantities and thin coatings, both fluids will have similar
coloring and feel slippery to the touch. During the exterior inspection, if
residual fluids on aircraft surfaces cannot be identified, contact local
Maintenance or call the MCC through the Dispatcher for guidance.

Fluid Application Methods
De/anti-icing can be performed using a one or two step procedure.
• One step procedure - This procedure is a combination of deicing
and anti-icing performed at the same time with the same fluid
(de/anti-icing). The fluid used to deice the aircraft is always heated
and remains on the surface to provide anti-icing protection. This
procedure can be repeated so as to minimize the time required to
complete the final application of fluid.
• Two step procedure - This procedure consists of two distinct fluid
applications. The first step, deicing with a heated fluid, is followed
by the second step, anti-icing, as a separate fluid application.
Normally, Type II or Type IV fluid is used during the second step;
however, Type I or Type III fluid may be used.
Note: Areas in front of the most forward passenger door are normally
treated only with Type I or Type III fluid. International stations
may use a thin mixture of Type II or Type IV fluid when Type I
or Type III fluid is not available.
Note: Holdover time starts when the final application begins in either
the one step or two step procedure.
Forced Air Deicing
At some stations, forced air deicing equipment is used to facilitate
contamination removal. Forced air deicing utilizes an air stream to help
remove frozen accumulations from an aircraft with or without deicing
fluid. Forced air deicing has the advantage of reducing the total amount of
glycol needed for deicing, providing economic and environmental
benefits. Forced air only (without fluid) may be especially helpful for
removing frozen accumulations from RON aircraft surfaces.
Forced air applications (with or without fluid) may not eliminate the need
for conventional de/anti-icing procedures. After a forced air application
has occurred, conventional deicing (using fluid only) may be needed to
ensure complete contamination removal.
Holdover times are not associated with forced air deicing. To use Type I
holdover time tables, anti-icing using heated Type I fluid without forced air
must occur. To use Type II, Type III, or Type IV holdover time tables,
anti-icing using Type II, Type III, or Type IV fluid without forced air must
occur.
The post-de/anti-icing check and report (below) should still occur even if
forced-air deicing is the only task performed.

De-/Anti-icing Checks
There are four types of de/anti-icing checks: Post De/Anti-icing Check,
Flight Deck Check, Cabin Check, and External Check.
Post De/Anti-icing Check
This check is an integral part of the de/anti-icing process. After aircraft
de/anti-icing is complete, the deicing ground crew performs a Post
De/Anti-icing Check to confirm that the critical surfaces are free of any
contamination. Confirmation that the Post De/Anti-icing Check has been
successfully completed will be communicated to the pilots during the Post
De/Anti-icing Report by stating; “POST DE/ANTI-ICING CHECK
COMPLETE”.
Flight Deck Check
This check is an integral part of the holdover time and is performed by the
pilots. Because of the limitations and cautions associated with the use of
the Holdover Time Tables, the pilots must not rely on the use of holdover
times as the sole determinant that the aircraft is free of contamination.
They must continually assess the current weather, environmental
conditions, and the aircraft’s condition. Several Flight Deck Checks are
required during the holdover time period to maintain awareness of the
aircraft’s condition.
The Flight Deck Check is performed by the pilots just prior to takeoff and
is required anytime:
• Ground icing conditions exist, and
• The holdover time is still valid.
The Flight Deck Check consists of:
• A check of representative aircraft surfaces which are visible from
the flight deck.
• If desired or if any doubt exists, conduct a Cabin Check.
When circumstances do not permit a satisfactory visual check from inside
the aircraft, return to the designated area and:
• Have ground de-icing crew perform an External Check, or
• If any doubt exists as to the condition of the aircraft, repeat the
Ground De/Anti-icing procedure.

SP.16.30
December 18, 2007
Supplementary Procedures Adverse Weather
737NG Operations Manual
Cabin Check
This check is performed by the pilots and is required:
• Any time the aircraft has been de/anti-iced, and holdover time is
exceeded during conditions of frost, freezing fog, or snow, or
• Within 5 minutes of takeoff any time a pilot-assessed change in
intensity is to be used, or
• When doubt exists after conducting the Flight Deck Check, or
• During conditions of heavy snow (provided Type IV fluid has been
used for anti-icing).
Since clear ice formation cannot be detected visually from inside the
aircraft, the Cabin Check is not authorized when:
• Type I fluid has been applied during freezing drizzle.
• Type II , Type III, or Type IV fluid has been applied during
freezing drizzle, light freezing rain, or rain on cold soaked wings
and holdover time has expired. Secondary de/anti-icing or an
External check must be accomplished prior to takeoff.
• Ice pellets have fallen.
The Cabin Check consists of a visual inspection of all representative
aircraft surfaces which are visible from the best vantage point(s) in the
cabin. Normally, de/anti-icing fluid failure will first occur on the leading
or trailing edges of the wing rather than the mid-chord. Therefore, the
leading edges and upper surfaces of both wings must be visually checked
for evidence of fluid failure. Additionally, engine inlets must be inspected
for contamination. Takeoff must occur within five minutes of the most
recent check.
The ability to adequately perform this check from inside the aircraft is
highly dependent upon several factors. Lighting conditions, cleanliness of
cabin/flight deck windows, and outside visibility may severely hinder or
prevent the pilot’s ability to satisfactorily assess aircraft surfaces for
contamination. When circumstances do not permit a satisfactory visual
check from inside the aircraft, return to the designated area and:
• Have ground de-icing crew perform the External Check.
• If any doubt exists as to the condition of the aircraft, repeat the
ground de/anti-icing procedure.

External Check
This check is performed by the de/anti-icing ground crew and is required
anytime:
• Doubt exists after conducting a Cabin Check, or
• The aircraft has been anti-iced with Type II, Type III, or Type IV
fluid, and holdover time is exceeded during freezing drizzle, light
freezing rain, or rain on cold soaked wings.
This check consists of a close visual inspection of the aircraft’s upper wing
surfaces and leading edges for frozen contamination. Takeoff must occur
within five minutes of the External Check.
If the External Check cannot be accomplished, return for secondary
de/anti-icing.
CAUTION: An External Check is not authorized during freezing
drizzle when Type I fluid is used.
Contact local operations for specific locations on the airfield to accomplish
the External Check. Be aware that some stations may conduct secondary
de/anti-icing as an alternative to the External Check.
Visual Indications of Loss of Fluid Effectiveness
It is difficult to determine when anti-icing fluid is beginning to fail,
however, when any ice or snow can be seen accumulating on treated
surfaces, the fluid has lost its effectiveness. Any ice, frost, or snow on top
of deicing or anti-icing fluids must be considered as adhering to the
aircraft, and secondary de/anti-icing must be accomplished prior to
takeoff.
• Normally, de/anti-icing fluid failure will first occur on the leading
or trailing edges of the wing rather than the mid-chord. However,
when the aircraft is pointing downwind the mid-chord will fail
first.
• The leading edges and upper surfaces of both wings must be
visually checked for evidence of fluid failure.
• If the leading edges and upper surfaces of both wings cannot be
inspected from the cabin, return for an External Check or
secondary de/anti-icing.
Type I Fluid
When Type I fluid has lost its effectiveness, frozen precipitation will begin
to accumulate on the aircraft surface in much the same manner as it would
on a nontreated surface.

Communication Procedures
Any airport specific deicing procedures will be contained in the Airway
Manual, 10-0 Delta Special Pages (green pages), or noted in the Airport
Remarks section of the flight plan.
It is critical to establish communications with the ground crew prior to
commencing de/anti-icing. Once the deicing operation commences, any
aircraft movement or changes in configuration must be coordinated with
the ground crew.
Post De/Anti-icing Report
After the aircraft has been de/anti-iced, a Post De/Anti-icing Report must
be directly communicated to the Captain using the format specified on the
GROUND DE/ANTI-ICING procedure card. The pilot is required to read
back this information to verify accuracy.
Note: A report is not required when the aircraft is deiced due to frost,
prior to the pilot’s arrival, and no active frost is forming.
Holdover Times
Use of Holdover Time Tables
Holdover times provide an operational guideline for departure planning.
They must be used in conjunction with the Flight Deck Check. Holdover
Time Tables are located in this section.
Holdover times published in the tables are only approximate and must be
adjusted after considering all variables. The source of the Holdover Time
Tables is the Aerospace Division of the Society of Automotive Engineers
(SAE). Time data is derived from an analysis of testing conducted in field
and laboratory conditions, as well as airline operational experience.
Numerous factors affect the actual time that anti-icing fluid will provide
protection against frozen contamination.
The times specified in the tables represent the approximate holdover times
for seven categories of active precipitation.
• Frost.
• Freezing fog.
• Snow.
• Freezing drizzle.
• Freezing rain (light).
Copyright © Delta Air Lines, Inc. See title page for details.
December 18, 2007
SP.16.35
Supplementary Procedures Adverse Weather
737NG Operations Manual
• Ice pellets
• Rain on cold soaked wings.
Three precipitation categories specify a time range (snow, freezing drizzle,
and rain on cold soaked wings), and four categories specify a single time
(freezing fog, frost, light freezing rain and ice pellets).
Whenever a time range is given, the lower time in the range is for moderate
precipitation conditions and the upper time is for light conditions.
When a single time is specified in the table, it represents the approximate
holdover time limit for that weather condition. However, it may be
necessary to adjust the holdover time downward after considering other
environmental factors.
Establishing Holdover Time
A holdover time is established using the following five steps.
(1) Obtain the Post De/Anti-icing Report from the ground crew and
read back the information. The following data from the report is
used to establish a holdover time:
• Fluid type: Type I, Type II, Type III, or Type IV.
• Fluid concentration: Mixture information is only required for
Type II, Type III, or Type IV fluid. There are no fluid mixture
break outs on the Type I Holdover Time Table because dilution
ratios do not significantly affect holdover time for Type I fluids.
• Local time that the final (anti-icing) fluid application began.
This is the point at which the holdover timing starts.
(2) Determine the current weather conditions (OAT, type of
precipitation, and intensity of precipitation).
• OAT is determined by the most current weather report or ATIS.
• The Holdover tables allow pilots to determine holdover times
based partly upon the type and intensity of the frozen
precipitation that is falling.
• The type and intensity of frozen precipitation (light, moderate,
or heavy) is officially determined by the most current official
weather report (e.g.,from National Weather Service [NWS],
NWS-approved automated system, or other agent approved by
the NWS).
• If at any time a pilot assesses intensity greater than that being
reported, he/she shall use the heavier precipitation when
entering the holdover tables for holdover time.
Copyright © Delta Air Lines, Inc. See title page for details.
SP.16.36
December 18, 2007
Supplementary Procedures Adverse Weather
737NG Operations Manual
• If, in the pilot’s judgement, the intensity is less than that being
reported, the pilot shall request (e.g., to the tower or trained
weather observer) a new observation be taken and reported or
shall wait long enough for an update to an automated
meteorological observation to be taken and reported as
applicable.
• A pilot may act on their own assessment of lesser
precipitation intensity only in those cases concerning
snowfall or ice pellets where the officially reported (e.g.,
from NWS, NWS-approved automated system, or other
agent approved by the NWS) meteorological precipitation
intensity is grossly different from that which is obviously
occurring. (For example: precipitation is reported when
there is no actual precipitation occurring.)
• If an adjustment to intensity is pilot-assessed, the pilots
shall communicate the newly assessed intensity to flight
control via ACARS.
• If a pilot acts based upon their own assessment that
precipitation intensity levels are LOWER than the official
reported intensity level, a Cabin Check is required within
the 5 minutes preceding takeoff.
• Pilot assessment of precipitation intensity levels may only be
used when there is enough natural sunlight or artificial lighting
available to provide adequate exterior visibility. All windows
through which the assessment is made must be adequately
transparent so as to not restrict the pilot’s visibility under the
lighting conditions present.
• The Snowfall Intensities as a Function of Prevailing Visibility
chart in the Flight Crew Operations Manual, Volume 1, is based
on prevailing visibility and allowances are made for the effects
of night light conditions.
• Ice pellet intensity shall be assessed using the following criteria:
• Light - scattered pellets that do not completely cover
exposed surfaces regardless of duration
• Moderate - slow accumulation on the ground
• Heavy - rapid accumulation on the ground
• Pilots are not permitted to self-assess intensity in the case of
reported freezing drizzle or freezing rain unless no precipitation
is actually falling. Freezing drizzle and freezing rain quickly
adhere to cold surfaces and can be difficult to see; for this
reason, if conditions are reported or anticipated the aircraft shall
be de-iced and/or treated with anti-icing fluid as a precaution
against encountering these conditions during taxi-out.

SP.16.37
Supplementary Procedures Adverse Weather
737NG Operations Manual
(3) Based on all the information obtained in steps 1 and 2, reference
the appropriate Holdover Time Table and determine:
• A single time from the frost, freezing fog, light freezing rain or
ice pellets column, or
• A time range from the snow, freezing drizzle, or rain on cold
soaked wings column.
(4) If a single time was extracted from the table, go to step 5. If a
time range was extracted, determine a specific holdover time
from this range by assessing:
• Intensity of precipitation. As a general rule, holdover time
ranges should be interpreted as follows:
• Light conditions = Upper end of time range.
• Moderate conditions = Lower end of time range.
• Heavy conditions = Less than the lower time value.
• When determining intensity, the pilots must consider the rate,
density, and moisture content of the precipitation. For example,
wet snow is considered more intense than dry/powdery snow
and will have a lower holdover time. Wet snow occurs at or near
freezing temperatures of -1°C (30°F) or above.
(5) Further refine the determined holdover time after considering the
following additional factors:
• Environmental factors - Jet blast, high wind velocity, and wind
direction may cause anti-icing fluid to flow off aircraft surfaces
thus reducing holdover time. Blowing snow due to wind or jet
blast could decrease holdover time by increasing the amount of
precipitation contacting aircraft surfaces and diluting the fluid.
Solar radiation from direct sunlight may increase holdover time
by warming aircraft surfaces.
• Aircraft skin temperature - Although this is difficult to
determine, pilots need to be aware that aircraft skin temperature
lower than OAT may decrease holdover time. One of the best
ways to assess wing skin temperature is by referencing the fuel
temperature, if available. Fuel temperature significantly lower
than OAT may decrease holdover time.
• Operational experience of the pilots - For example, pilots who
rarely fly in ground icing conditions may feel more comfortable
using more conservative holdover times. Additionally, any
background knowledge or experiences can be applied by the
pilots.

737NG Operations Manual
Adjusting Holdover Time
A continuous assessment of weather and environmental conditions in
conjunction with the Flight Deck Check is required during the holdover
time period. Changing conditions may increase or decrease fluid
effectiveness, necessitating a holdover time adjustment.
• A change in OAT.
• A change in type or intensity (rate or density) of precipitation.
Snow changing to light freezing rain, or light snow changing to
heavy snow will decrease holdover time. Conversely, moderate
snow changing to light snow may increase holdover time. Presence
of ice pellets precipitation may necessitate similar adjustment.
• Jet blast, an increase in wind velocity, or a change in wind direction
will decrease holdover time.
Exceeding Holdover Time
The Captain is responsible for monitoring the status of the aircraft exterior
for frozen contamination. The pilot performs periodic Flight Deck Checks
to ensure the aircraft is free of contamination during the time between
anti-icing and takeoff, whenever the holdover time is still valid.
When holdover time is exceeded, the required course of action will depend
upon the type of active precipitation and the type of fluid used to anti-ice.

After proper deicing and anti-icing, takeoff is allowed under conditions of light ice pellets,
moderate ice pellets, and ice pellets mixed with other forms of precipitation by using the
"Ice Pellet Holdover Times" table and accompanying footnotes. If the holdover time has
been exceeded, the aircraft must be completely deiced, and if precipitation is still present,
anti-iced again prior to a subsequent takeoff. The ice pellet holdover time cannot be
extended by a cabin check or an external check of the aircraft critical surfaces.

Ice pellets generally remain in the frozen state, imbedded in anti-icing fluid, and are not
absorbed by fluid in the same manner as other forms of frozen precipitation. In the past,
presence of a contaminant not absorbed by the fluid would be an indication of a failed fluid.
Ice pellets imbedded in anti-icing fluid are difficult to detect using a cabin check.
Therefore, a cabin check during ice pellet conditions may not be of value and is not
required.

Hot Weather Operation
During ground operation the following considerations will help keep the
airplane as cool as possible:
• flight deck windows must be kept closed.
• While the airplane is electrically powered, packs should be run or
cooling air supplied to the airplane when the OAT exceeds 40° C
(103° F) to protect the reliability of electrical and electronic
equipment in the airplane.
• If cooling air is available from an outside source, the supply should
be plugged in immediately after engine shutdown and should not
be removed until just prior to engine start.
• Keep all doors and windows, including cargo doors, closed as
much as possible.
• Electronic components, window heat and radar contribute to a high
temperature level in the flight deck should be turned off while not
needed.
• Windshield air, foot air vents and all the air outlets should be open.
• Open all passenger cabin gasper outlets and close all window
shades on the sun–exposed side of the passenger cabin.
Note: If only cooling air from a ground air conditioning cart is
supplied (no pressurized air from the APU or ground external
air), then the TAT probes are not aspirated. Because of high TAT
probe temperatures, the FMC’s may not accept an assumed
temperature derate. Delay selecting an assumed temperature
derate until after bleed air is available.
• Heat build up from the pneumatics within the wing body areas may
cause WING-BODY OVERHEAT lights to illuminate. After
exiting the landing runway and during ground servicing, consider
positioning the flaps to 1 to assist in dissipating heat from these
areas. If this is accomplished, stations personnel should be advised.
Brake temperature levels may be reached which can cause the wheel fuse
plugs to melt and deflate the tires. Consider the following actions:
• Consideration for brake cooling should be taken into account when
operating on runways and taxiways exposed to high temperatures
since these areas maintain temperatures considerably above
ambient. Excessive use and riding of brakes should be avoided.
Intermittent brake usage provides a cooling period between
application. Allow the airplane to accelerate, then brake to a very

slow taxi speed and release the brakes completely. Use of reverse
thrust to reduce taxi speed is not recommended.
• Be aware of brake temperature buildup when operating a series of
short flight segments. The energy absorbed by the brakes from
each landing is cumulative.
• Extending the landing gear early during the approach provides
additional cooling for tires and brakes.
During flight planning consider the following:
• High temperatures inflict performance penalties which must be
taken into account on the ground before takeoff.
• Alternate takeoff procedures (No Engine Bleed Takeoff, Improved
Performance, etc.)
Operation in Heavy Rain or Hail
When flight in or near heavy rain or hail is encountered or anticipated,
accomplish the following:
If heavy rain or hail is encountered:
ENGINE START switches ....................................................... CONT
Thrust Levers ............................................................... Adjust Slowly
If thrust changes are necessary, move the thrust levers slowly. Avoid
changing thrust lever direction until engines have stabilized at a
selected setting.
Turbulence
During flight in light to moderate turbulence, the autopilot and/or
autothrottle may remain engaged unless performance is objectionable.
Increased thrust lever activity can be expected when encountering wind,
temperature changes and large pressure changes. Short–time airspeed
excursions of 10 to 15 knots can be expected.
Passenger signs .................................................................................. ON
• Advise passengers to fasten seat belts prior to entering areas of reported
or anticipated turbulence.
• Instruct flight attendants to check that all passengers' seat belts are
fastened.

Windshear
Windshear is a change of wind speed and/or direction over a short distance
along the flight path. Indications of windshear are listed in the Windshear
non-normal maneuver in the QRH.
Avoidance
The flight crew should search for any clues to the presence of windshear
along the intended flight path. Presence of windshear may be indicated by:
• Thunderstorm activity
• Virga (rain that evaporates before reaching the ground)
• Pilot reports
• Low level windshear alerting system (LLWAS) warnings.
Stay clear of thunderstorm cells and heavy precipitation and areas of
known windshear. If the presence of windshear is confirmed, delay takeoff
or do not continue an approach.
Precautions
If windshear is suspected, be especially alert to any of the danger signals
and be prepared for the possibility of an inadvertent encounter. The
following precautionary actions are recommended if windshear is
suspected:
Takeoff
• Use maximum takeoff thrust instead of reduced thrust.
• For optimum takeoff performance, use flaps 5, 10 or 15 as selected
by AWABS. If multiple flap settings are offered, use the highest
available setting for the runway in use to improve tail skid
clearance during rotation.
• Use the longest suitable runway provided it is clear of areas of
known windshear.
• Consider increasing Vr speed using the runway allowable takeoff
weight (RATOW) from the AWABS. Refer to the ODM to
determine the higher rotation speed, not to exceed actual gross
weight Vr + 20 knots. Set V speeds for the actual gross weight.
Rotate at the adjusted (higher) rotation speed. This increased
rotation speed results in an increased stall margin and meets
takeoff performance requirements. If windshear is encountered at
or beyond the actual gross weight Vr, do not attempt to accelerate
to the increased Vr but rotate without hesitation.

SP.16.50
June 9, 2008
Supplementary Procedures Adverse Weather
737NG Operations Manual
• Be alert for any airspeed fluctuations during takeoff and initial
climb. Such fluctuations may be the first indication of windshear.
• Know the all–engine initial climb pitch attitude. Rotate at normal
rate to this attitude for all non–engine failure takeoffs. Minimize
reductions from the initial climb pitch attitude until terrain and
obstruction clearance is assured, unless stick shaker activates.
• Crew coordination and awareness are very important. Develop an
awareness of normal values of airspeed, attitude, vertical speed,
and airspeed build–up. Closely monitor vertical flight path
instruments such as vertical speed and altimeters. The pilot
monitoring should be especially aware of vertical flight path
instruments and call out any deviations from normal.
• Should airspeed fall below the trim airspeed, unusual control
column forces may be required to maintain the desired pitch
attitude. Stick shaker must be respected at all times.
Approach and Landing
• Use flaps 30 for landing.
• Establish a stabilized approach no lower than 1,000 feet above the
airport to improve windshear recognition capability.
• Use the most suitable runway that avoids the areas of suspected
windshear and is compatible with crosswind or tailwind.
limitations. Use ILS G/S, G/P, VNAV path or VASI/PAPI
indications to detect flight path deviations and help with timely
detection of windshear.
• If the autothrottle is disengaged, or is planned to be disengaged
prior to landing, add an appropriate airspeed correction (correction
applied in the same manner as gust), up to a maximum of 20 knots.
• Avoid large thrust reductions or trim changes in response to sudden
airspeed increases as these may be followed by airspeed decreases.
• Crosscheck F/D commands using vertical flight path instruments
• Crew coordination and awareness are very important, particularly
at night or in marginal weather conditions. Closely monitor the
vertical flight path instruments such as vertical speed, altimeters,
and glideslope displacement. The pilot monitoring should call out
any deviations from normal. Use of autopilot and autothrottle for
the approach may provide more monitoring and recognition time.
Recovery
Accomplish the Windshear Escape Maneuver found in the Non–Normal
Maneuvers section of the QRH.

Guidelines for Contaminated Runways
When there is contamination on the runway or the braking action is less
than good, Captains must evaluate crew, aircraft, and environmental
conditions in determining the safety of operating their flight.
For takeoffs, refer to the Flight Operations Manual (FOM), Chapter 5,
Flight Planning, Weight Data Record (WDR), Contaminated Runways, for
additional guidance.
For landings, refer to the Airway Manual, Chapter 4, Weather, Braking
Action for additional guidance.
Procedure Guidance
General
• Consider crew capability.
• Consider current Maintenance Carry Overs (MCO’s) - reversers,
antiskid, etc.
• Consider type and amount of contaminant.
• Consider source and age of reported braking action.
• Consider usable runways and taxiways (NOTAMS, ATIS, etc.).
Taxi
• Be aware that ramps and taxiways may be very slippery.
• Be cautious of jet blast on contaminated surfaces. People and
equipment behind may be in jeopardy.
• Taxi onto and off runways at an extremely slow speed. Nose wheel
slippage may occur causing the aircraft to continue straight ahead
and possibly off the paved surface.
Crosswind
• On slippery runways, crosswind guidelines are a function of
runway surface condition, airplane loading, and assume proper
pilot technique.
• The following crosswind guidelines are applicable to all Delta
aircraft for takeoff and landing.

Notes:
• Crosswind guidelines are not considered limitations. Refer to
AOM, Volume 1, Limitations chapter for crosswind limits.
• Reduce crosswind guidelines by 5 knots with a reverser
inoperative.
• When multiple reports are present, e.g. “Braking Action Fair to
Good”, use the lower crosswind value
Takeoff
• Do not take off with braking action report of NIL by any air carrier
aircraft or airport operator.
• A rolling takeoff is strongly advised when the crosswind exceeds
20 knots.
• Do not take off with standing water, slush, or wet snow in excess of
1/2 inch (1.2 cm) depth.
• Do not take off in dry snow in excess of 4 inches or 10 cm depth.
Landing
• Do not land with a braking action report of NIL by any air carrier
aircraft or airport operator in the landing or rollout portion of the
runway.
• Do not land with standing water, slush, or wet snow in excess of
1 inch (2.5 cm) depth.
• Do not land in dry snow in excess of 4 inches or 10 cm depth.
• Land as early in the touchdown zone as possible.
• Ensure the ground spoilers are extended at touchdown.
• Use autobrakes, if available.
• Use reverse thrust judiciously.
• Do not assume the last 2,000 feet of the runway will have braking
action as good as the touchdown zone.
• Be aware of the possibility of white out effect from reverse thrust
use in dry snow.
