Performance Data
NOISE LEVELS
The following noise levels comply with 14 CFR Part 36, Appendix B
(Stage 4) maximum noise level requirements and were obtained by
analysis of approved data from noise tests conducted under the provisions of Part 36, Amendment 36-28. The noise measurement and evaluation procedures used to obtain these noise levels are considered by
FAA to be equivalent to the Chapter 4 noise level required by the International Civil Aviation Organization (ICAO) in Annex 16, Volume 1,
Appendix 2, Amendment 7, effective March 21, 2002.
No determination has been made by the Federal Aviation Administration that the noise levels in this manual are or should be acceptable or
unacceptable for operation at, into, or out of any airport.
These noise values are stated for reference conditions of standard atmospheric pressure at sea level, 25°C ambient temperature, 70% relative
humidity, and zero wind.
CERTIFIED NOISE LEVELS
Flyover and lateral noise levels were determined at the maximum takeoff weights listed below, 137 KIAS climb speed, 8° flaps, and anti-ice
systems off. The flyover noise level includes an engine power cutback
to a thrust that allows level flight in the event of an engine failure.
Landing approach noise levels were determined for a three degree
glide slope with gear down, maximum landing weights listed below,
approach speed of 133 KIAS, and 40° flaps.
The noise levels established in compliance with 14 CFR Part 36, Appendix B (Stage 4) are:
