As a member of the FAA/Industry Transport Airplane Performance Planning (TAPP) Work Group, NBAA has posted four instructional videos it helped create on aircraft performance planning on its website and YouTube channel. TAPP's goal is to improve pilot and operator understanding of transport aircraft performance, which leads to improved planning and operation. The work group's inaugural offering in a planned series of videos addresses long-standing questions and issues frequently faced in planning the performance of transport category airplanes, including FAR Part 91 and 135 requirements. View the videos.

Many operators are unaware there are alternative procedures for OEI takeoff planning, but NBAA's Domestic Operations Committee has authored a white paper titled, "One Engine Inoperative Takeoff Planning and Climb Performance." Its objective: "To promote operator knowledge, operator application and operator training issues surrounding transport airplane takeoff performance, Part 91 and 135 operators alike, specifically showing that the current practice of planning for OEI takeoff obstacle avoidance and compliance with TERPS criteria is inadequate and potentially dangerous."

Have you declined to accept a Standard Instrument Departure (SID) because the aircraft you are flying cannot comply with the SID climb gradient if an engine failure occurs? Have you ever delayed your flight because of low visibility or low ceilings which required a climb gradient published on the SID or Obstacle Departure Procedures (ODP) in which your aircraft with one engine inoperative could not satisfy? Members of the NBAA Domestic Operations Committee have recently created an article that addresses one engine inoperative takeoff and climb performance planning. View the article.
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
