Abstract:Loss of control in the traffic pattern is one of the primary causes for fatal accidents in general aviation. For a number of years, the FAA Small Airplane Directorate has been working with industry and academia to significantly enhance general aviation safety by introducing advances in technology, such as evolved in-cockpit warning systems and increased use of augmented flight controls, and by developing new means of compliance for the airworthiness certification standards. To give manufacturers more flexibility in how to demonstrate compliance with certification standards, and in order to stimulate the introduction of novel flight energy management and warning technologies, the envisioned means of compliance are based on certification point scores. The present project was focused on evaluating the effects of different sensory modes in angle-of-attack warning systems (visual, aural, and haptic) along with the stall characteristics of common single-engine, Part 23 aircraft, in order to develop a means of compliance. The period of performance for the project was 02/20/2017 – 09/09/2019. The proposed means of compliance combines fixed performance thresholds for coordinated stalls with a point system for uncoordinated, feet-on-the-floor stalls, longitudinal control force changes, free aircraft pitching response during configuration changes, and enhanced warning systems. The report presents the proposed means of compliance for flight characteristics of non-aerobatic level 1 to level 4 airplanes and documents the underlying flight test data. Flight tests for the characterization of angle-of-attack warning methods were executed on a fly-by-wire DA42 research aircraft developed by the Technical University of Munich and operated by Diamond Aircraft in Wiener Neustadt, Austria. Flight tests for the study of common stalling characteristics were executed at Florida Institute of Technology in Melbourne, FL, on six different aircraft (Diamond DA40, Piper PA28, Cessna 172N, Mooney M20C, Cirrus SR20, and Citabria). In total, 39 flights (59.7 hours) were conducted for this program.
