ロール角保持状態でのラダー操作による横変位制御

Abstract

In general, lateral displacement deviation of an airplane from a reference flight path is compensated using an aileron with a changing roll angle and by turning. However, in aileron control, a pilot is required to operate the aileron with multiple phase-lead compensation. In this study, we propose a method of handling the lateral displacement control by rudder steering, holding its roll angle automatically using an aileron. Using rudder control in the roll angle hold state, the flight path is directly changed by a side force due to sideslipping. Therefore, the phase-lead compensation operation of a pilot is mitigated in contrast to aileron control. Then, experiments on the task of holding the flight path using a flight simulator are carried out. The experiments show that, in rudder control in the roll angle hold state, the pilot's control input is slower than in aileron control. This means that the pilot's work load is less than in aileron control. However, in some part of the pilot evaluation results, rudder control was slightly worse than aileron control. We inferred that the result is related to the pilot being unfamiliar with flight path correction in the roll angle hold state.
