Abstract:

Flight under instrument flight rules IFR is reported to be one of the most important factors contributing to aviator fatigue during helicopter operations. This study was initiated to collect visual and psychomotor performance data in an attempt to investigate and study the general visual performance of aviators during IFR conditions. Two groups of aviators, with varied experience levels, were the subjects. A NAC Eye Mark Recorder and the Helicopter In-Flight Monitoring System were utilized to collect the required data. The results indicated, among other findings, that pilot subjective opinion does not agree with objective data. Additionally, the attitude indicator and radio compass comprised over 60 of the pilots total visual workload, while the aircrafts status gauges were monitored less than 10 of the total time. These data should provide invaluable information concerning the visual requirements of pilots for safe helicopter operations. Author
