Operations under a single pilot instrument flight rule 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 the pilot’s skills and the pilot workload. A pilot workload evaluation method has been established which is partly based on the time and motion studies and which mainly concentrates on the pilot’s information processing. The time-record of a 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 a 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 the results of the novice pilots show a high workload continuously during the whole flight.
