Abstract : There have been numerous recent documented and anecdotal reports of aircrews experiencing psychophysiological disturbances, visual illusions and sickness following the use of flight simulators. Symptoms of simulator sickness occur not only during flight, but in some individuals, have lasted up to several hours post exposure. Furthermore, simulator aftereffects may be delayed; some aircrews report symptom onset as late as eight to ten hours post utilization. Incidents of simulator sickness have been documented in fighter, attack, patrol and helicopter simulators. These occurrences have been reported in both motion-base and fixed-base simulators, to pilots and other aircrewmen, as well as instructors. Preliminary data suggest that more experienced aircrewmen are at greater risk and that such factors as wide field-of-view and visual/inertial lag contribute to the problem. Data on pilot experience and exposure factors, symptomatology, scores on postural disequilibrium tests, video-game performance and engineering design aspects in two different Navy helicopter simulators are presented, along with a brief review of past simulator sickness studies.
