Simulator Sickness in the CH-47 (Chinook) Flight Simulator.

摘要

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. (aw)
