Transport Airplane Performance Planning

At NBAA 2012, FAA's Flight Standards Division presented a workshop on transport airplane performance planning.  Hosted by AFS 410's Manager Coby Johnson and assisted by members of the Transport Airplane Performance Planning (TAPP) Working Group, this workshop introduced a series of videos intended to address long-standing questions in the operator community regarding one-engine-inoperative takeoff obstacle clearance, landing runway runway performance assessment, and a host of other topics related to turboprop airplane performance.  Present at the meeting were FAA and industry subject matter experts to answer participants questions on this subject.  

Declared Distances

This video provides pilots and operators an overview of the topic of declared distances. It defines these distances and how they relate to the part 25 takeoff & landing runway requirements. It demonstrates the significance of declared distances in meeting runway and airport design standards. It also discusses the applicability of declared distances during the actual takeoff and landing operation. In addition, the video cautions pilots against overreliance in FMS takeoff and landing performance computations where the stored runway information does not include a runway's declared distances.

Wet Runway Takeoff Performance

This video explores the takeoff performance planning requirements on a wet runway. It explains unique certification differences for those airplanes with part 25 wet runway takeoff distance and wet runway V1 data. It also shows why the wet runway takeoff distance requirements may not always be the most limiting condition when taking off from a wet runway. The video cautions against sole reliance on FMS generated performance data.

Planning For Takeoff Obstacle Clearance

 This video reviews the part 25 takeoff performance certification rules applicable to one-engine-inoperative (OEI) takeoff climb performance and obstacle clearance. The video addresses the OEI takeoff obstacle clearance rules applicable to part 121 and part 135 operators of turbine-powered airplanes and the FAA-approved means by which an operator ensures compliance with these rules. It compares these rules to the all-engines-operating IFR takeoff requirements applied to Standard Instrument Departures (SIDs) and Obstacle Departure Procedures (ODPs).

Landing Distance

This video discusses the landing performance requirements in transport category airplanes. It reviews the part 25 certification requirements and their applicability to the landing distance data furnished in the AFM. It distinguishes between the weight limitations applicable at time of takeoff with respect to landing field length for part 121 and part 135 operators and the actual landing distance requirements upon arrival at the destination or alternate airport. Finally, it reviews the guidance contained in SAFO 06012 regarding landing distances assessments.
