PURPOSE

This specification contains the demonstration requirements of the high angle of attack (AOA) flight characteristics of piloted airplanes. Typical demonstration objectives subject to this specification are the verification of service and permissible flight limits, evaluation of natural and artificial stall and loss-of-control warning, evaluation of flight control system functions including AOA limiting and departure prevention devices, and determination of out-of-control characteristics and recovery techniques. A build-up approach to high AOA flight test, using analysis, simulation, and flight test validation, is mandatory to determine compliance with the design requirements and obtain suitable information for the Flight Manual. Flight test demonstration requirements are a function of airplane Class and specific direction from the procuring activity. Resistance to departure, from controlled flight and prevention of departures are given the same attention as that directed toward recovery from post-departure gyrations (PDG), deep stalls, and spins. The Backup Information and User Guide to this Specification elaborates the experience and test and analysis techniques which support the following requirements.
