単独計器飛行時のワークロード評価法に関する研究

Abstract

Operations under single pilot instrument flight rules for general aviation aircraft are known to be one of the most demanding pilot tasks. Pilot workload measurements using a PC-based flight simulator have been done to investigate pilot skills and the pilot workload. A pilot workload evaluation method has been established that is partly based on the time and motion studies and that mainly concentrates on the pilot's information processing. The time-record of pilot's eye movement has been used for the evaluation. Pilots who have different flight experiences attended the tests. Comparisons between the results by experienced pilots and those by novice pilots were made. It was shown that the relatively correct pilot workload has been evaluated by the present method. Results for the VOR tracking flight showed that the workload of the experienced pilots increases only when the airplane attitude has been changed, while results of the novice pilots show high workload continuously during the whole flight.
