The U.S. Navy has conducted a survey in 10 flight trainers where motion experience questionnaires and performance tests were administered to pilots before and after 1200 separate exposures. From these measures on pilots, several findings emerged: (1) specific histories of motion sickness were predictive of simulator sickness symptomatology; (2) postural equilibrium was degraded after hops in some simulators; (2) self-reports of motion sickness symptomatology revealed three major symptom clusters; gastrointestinal, visual, and vestibular; (3) certain pilot experiences in simulators and aircraft were related to severity of symptoms experienced; (4) simulator sickness incidences varied from 10 to 60 percent; (4) substantial perceptual adaptation occurs over a series of hops; (6) in two moving-base flight trainers motion sickness incidence appeared to be related to the amount of acceleration (energy) experienced in frequency ranges around 0.2 Hz. The findings are discussed in the context of sensory conflict theory and recommendations are made for simulator design criteria. Suggestions are made as to how to relate simulator and equipment configuration to the separate symptom clusters as an aid to the diagnosis of specific problems within particular simulators. It is believed that this holds promise in diagnosing simulator equipment problems (e.g, alignment, inertial motion profile, cue asynchrony) since different symptom clusters may be related to different equipment features.
