Fixed based flight simulator experiments were conducted to investigate the influences of wideness of front view for pilot's roll control. In these experiments, the airplane's motion was considered as a single-degree-of-freedom system in roll, and three front views having different view-angle were provided. The results of these experiments showed that the pilot's roll control characteristics, and the pilot's sensing parameter and reaction time for rolling motion were influenced by the differences of wideness of front view in flight simulator.
