Abstract : A study has been made of pilot human factors related to stall/spin accidents of supersonic fighter aircraft. The military specifications for flight at high angles of attack are examined. Several pilot human factors problems related to stall/spin are discussed. These problems include: unsatisfactory nonvisual warning cues; the inability of the pilot to quickly determine if the aircraft is spinning out of control, or to recognize the type of spin; the inability of the pilot to decide on and implement the correct spin-recovery technique; the inability of the pilot to move, caused by high angular rotation; and the tendency of pilots to wait too long in deciding to abandon the irrecoverable aircraft. Psycho-physiological phenomena influencing pilot's behavior in stall/spin situations include: channelization of sensory inputs; limitations in precisely controlling several muscular inputs; inaccurate judgement of elapsed time, and disorientation of vestibulo-ocular inputs. Results are given of pilot responses to all these problems in the F14A, F16/AB, and F/A-18A aircraft. The use of departure/spin resistance and automatic spin prevention systems incorporated on recent supersonic fighters are discussed. These systems should help to improve the stall/spin accident record with some compromise in maneuverability.
