Abstract : Singer-Link and the Air Force Human Resources Laboratory (AFHRL), Williams Air Force Base, combined efforts to investigate specific visual requirements during low-level, high-speed flight. Visual information requirements were hypothesized, and an experiment was designed to systematically test the effects of various visual cues upon flight performance. The experiment tested the effects of visual scene elements in supporting simulator flight tasks of experienced Air Force fighter pilots. Specific visual factors studied were: 1.) the importance of surface texture, 2.) the importance of 3-D objects and object type, and 3.) the effect of turning and bank angle upon flight performance. Pilot subjects were able to control flight at a mean altitude of 198 feet and at an airspeed of 480 knots. Test results indicate that both 3-D objects and 2-D terrain surface texture aid controlled low-altitude flight. (Author)
