In an attempt to more closely associate the visual aspects of instrument flying with that of contact flight, a study was made of human response to peripheral vision cues relating to aircraft roll attitude. Pilots, ranging from 52 to 12,000 flying hours experience, were tested in a multi-engine aircraft simulator. Data on aircraft bank angle, heading, altitude, peripheral vision cue signals, pilot eye movement, and additional workload accomplishment were obtained during simulated flights involving a typical instrument flying maneuver.
