Abstract:One significant difference between real and simulated flight on the ground are the stimuli or cues provided to the pilot. Due to physical and/or cost constraints, it is nearly impossible to match all the cues experienced in the air in ground-based simulators. Motion cues, in particular, are severely affected by the limits imposed on the ground, such as the extent of travel and the dynamics bandwidth. Researchers have been struggling for decades to develop a better understanding on how pilots' behavior and performance in the simulator are affected by these limitations, and to determine the motion-cueing requirements appropriate to the purposes of the simulation. It has been demonstrated that motion cues can affect pilot-vehicle performance and pilot behavior in ground-based simulators. However, whether motion cues affect behavior and performance appears to be a function of pilot task, vehicle dynamics, and cueing quality (of motion and other cues). The experimental design also greatly affects the validity (whether the data answer the research question) and reliability (whether the results can be replicated) of a study. This paper is developing a systematic approach to re-examine past studies in an effort to develop a comprehensive understanding of the effects of motion in ground-based flight simulators.
