Cockpit crew of oceanic services with flight time of more than six hours experience sleep-loss and circadian rhythm disruption. Crew of short-haul services with flight time of less than two hours suffer from early departures, late finishes, and intensive takeoff and landing procedures that are workload demanding. Quantitative research is limited with respect to flight fatigue issues in Taiwan. The present research employed a structural equation modeling approach to conduct a path analysis and to identify the relationships among mental and physical fatigue, before and after flight duty. The empirical study indicated that for oceanic crew mental fatigue (MF) before flight duty influenced MF after flight duty. MF after flight duty also influenced physical fatigue (PF) after flight duty. For regional operations (flight time between two and six hours), PF after flight duty is influenced by PF before flight duty and MF after duty is influenced by PF after duty. With respect to short-haul flights, MF after flight duty is influenced by MF before flight duty, PF after flight duty is influenced by both PF before flight duty and MF after flight duty.
