FAA Releases Additional Guidance on Aircraft Climb Performance
The FAA added new guidance in the August 27, 2009 Aeronautical Information Manual (AIM) concerning expected aircraft performance on TERPS-based Standard Instrument Departure Procedures (SIDs) and Obstacle Departure Procedures (ODPs). The AIM now makes clear to pilots that these departure procedures assume normal aircraft performance and that all engines are operating. Contingency procedures addressing an engine failure or other emergency in flight that may occur after liftoff are the responsibility of the operator. This new guidance was included in the AIM in response to numerous inquiries by operators concerning the need to comply with a SID or ODP climb gradient following an engine failure on takeoff above V1 speed.
FAA Aeronautical Information Manual Section 5-2-8, revised August 27, 2009, covers Instrument Departure Procedures (DP), Obstacle Departure Procedures (ODP) and Standard Instrument Departures (SID)
This FAA Advisory Circular contains information on developing takeoff and initial climb-out airport obstacle analyses and in-flight procedures to comply with the takeoff limitation requirements of parts 121 and 135
