Abstract : Pilot interview data and analytic investigation indicated that the night attack environment was particularly hazardous with respect to spatial disorientation. Fifteen pilot subjects performed a tracking task representative of recovery from unusual attitudes while simultaneously being subjected to rotationally induced disorientation in a simulated cockpit. Motion pictures of geometric arrangements of flare patterns were presented for use as an orientation aid. Performance was evaluated against an attitude indicator and a 'no disorientation' condition. In addition to tracking parameters, results were evaluated on the basis of pilot opinion, body reactions, eye movement recordings and perceptual tests. Results indicated that air-dropped flares arranged in a triangular pattern were effective in establishing attitude control under conditions of disorientation. (Modified author abstract)
