Potential accidents and health problems related to fatigue remain a tremendous problem in commercial flight. This study was conducted to investigate fatigue risk factors among pilots in PT XYZ. There were 196 participants in the study. In order to gather more information, a questionnaire was administered, and a systematic in-depth interview was performed on each pilot individually. The Samn-Perelli Subjective Scale, designed specifically to measure fatigue, was used, and the measurements were analysed using regression and correlation analysis. Of the participants, 60.5% frequently experienced post-flight fatigue. Measurement of fatigue levels showed that 26 participants (13%) experienced physical fatigue, 61 participants (30.5%) experienced mental fatigue and 47 participants (23.5%) experienced emotional fatigue. Occupational and non-occupational factors played a substantial role in the occurrence of fatigue. Of the various risk factors (such as quality of sleep, quantity of sleep and working hours), the number of flight sectors showed a positive correlation with fatigue. In contrast, smoking habits, exercise, caffeine consumption, flight duration and napping showed negative correlations with fatigue. To reduce the occurrence of fatigue, the current established programmes at PT XYZ (which include limitations on flight time and working hours, and provision of resting time) should be continued.
