Book Description
This research measured simulator sickness both before and after exposure to a helicopter simulator that was being used for emergency procedures training. Research issues were the incidence and magnitude of simulator sickness, after effects, susceptibility, and the effect of simulator sickness on training effectiveness. A total of 474 AH-64A (Apache) Army aviators participated in this research. The Simulator Sickness Questionnaire (SSO) was administered prior to simulator exposure, immediately after simulator exposure, and twelve hours later. The incidence rate following simulator exposure was 68 percent. The SSQ Total Severity score was significantly larger immediately after exposure than it was prior to simulator exposure or twelve hours later. Age was significantly and positively correlated with SSO score, after the effect of total flight hours was held constant. Flight hours did not correlate with SSO score, after the effect of age was held constant. These results were consistent with postural instability theory. Both prior history of motion sickness and prior history of simulator sickness were significantly and positively correlated 'with SSO score. The strongest susceptibility factor noted in this research was prior history of simulator sickness. SSO score was not correlated with training effectiveness, as measured by a short behavioral test.

Book Description
For this report, helicopter simulator sickness literature was reviewed and analyzed to estimate the scope of the problem in the Army. The author concluded that pilot reluctance to divulge symptoms, in combination with the survey methods used, leads to underestimation of the incidence and severity of symptoms. Lack of truly anonymous survey procedures and potential adverse flying career consequences are suggested as reasons that the more severe symptoms and aftereffects may not be reported in surveys. Potential adverse career impact is also suggested as a probable reason for failure to find any relationship between simulator sickness aftereffects and accidents or safety incidents. Guidelines are suggested for minimizing the development of simulator sickness and the safety consequences of its aftereffects.

Book Description
The U.S. Army Aeromedical Research Laboratory conducted field studies of operational flight simulators to assess the incidence and severity of simulator sickness. Simulator sickness here refers to the constellation of motion sickness related symptoms that occur in simulators due to visual representation, motion base representation, or combination of the two representations of flight. The incidence rates and relative frequency of specific symptoms are presented. Correlational factors such as recent simulator experience, current state of health, overall flight expereience, mission scenario, and flight dynamics are presented. This report ranks the Army's flight simulators in comparision to the 10 Navy simulators studied by the Naval training systems Center, Orlando, Florida. The study further reinforces the need for studies to understand perceptual rearrangement, adaptation/readaptation, and pilot susceptibility to the effects of simulation. Design criteria for simulators, as well as those training guidelines necessary to cope with this phenomenon also must be addressed.

Book Description
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.

Book Description
The principal goal in this field study was to assess the incidence of simulator sickness in the CH-47 flight simulator. The results show that this simulator produces a lower incidence of simulator sickness than the three other Army visually coupled flight simulators. 18 percent of the sample may be at risk for simulator-induced posteffects. Eyestrain and headache were leading symptoms of asthenopia, while fatigue and sweating were leading symptoms associated with motion sickness. Of possible impact on the results are the sample of aviators surveyed and the scenarios flown. None of the aviators sampled were in a training/qualification status. All were rated in the CH-47 and flying for continuation and proficiency. Therefore, it could be assumed the scenarios flown were less structured and flown by aviators familiar with both the aircraft that does not fly a large amount of high maneuver content missions. This could lead to lower amounts of provocative scene variables such as low-level flight, maneuvering in close proximity to the ground, and high speed turns. 48 percent of the pilots' and 37 percent of the copilots' missions were under instrument conditions. Such a large percentage of time spent with no scene content could account for some of the lower SSQ scores. The use of NVGs in the CH-47 simulator is associated with higher scores on the SSQ.
