Simulator Study of the Effect of Visual-Motion Time Delays on Pilot Tracking Performance With an Audio Side Task

摘要

An experimental study has been made to determine the effect of time delay in the visual and motion cues in a flight simulator on pilot performance in tracking a target aircraft that was oscillating sinusoidally in altitude only. An audio side task was- used to assure that the subject was fully occupied at all times- The results of the study indicate that, within the test grid employed, about the same acceptable .time delay (250 msec) was obtained for a single air craft (fighter type) by each of two subjects for both fixed-base and motion-base conditions- Acceptable time delay is defined as the largest amount of delay that can be inserted simultaneously into the visual and motion cues before performance degradation occurs. A statistical analysis of the data was made to establish this value of time delay. Use of the audio side task provided quantitative data that documented the subject's work level.
