Abstract
When a human pilot controls aircraft, he relies on visual cues and motion cues. Especially visual cues are great part of information required for control. We thought of modifying the movement of the outside visual field. That is, pilot observes a virtual visual cue which is added a first-order lead compensation to the real roll response of aircraft. In this study we prepared two tasks, roll compensatory control task and holding flight path task. We investigate the effect of virtual visual cue using a fixed-based flight simulator. As a result, in a roll compensatory control task, pilot controls aircraft easier without getting task performance worse. But in a holding flight path task, pilot didn't control aircraft easier. Although only roll response is important cue in roll compensatory control task. In holding flight path task, not only roll response but also yaw response plays a great role. That shows that it is necessary to modify the dutch-roll oscillation component in the yaw response.
