ABSTRACT

Decision errors have been identified as a key factor in numerous aviation incidents and accidents. Whilst previous research indicates that fatigue may impair decisionmaking, the specific effects of fatigue on crew decision-making remains unclear. Consequently, this study seeks to investigate the effects of fatigue on flight crew decision-making. Volunteer flight crew from an Australian commercial airline participated in a simulator-based study. Crew were tested in an operationally realistic scenario that required the crew to make a complex decision. Preliminary analyses indicate fatigued crews adopt different approaches to decision-making compared to non-fatigued crew, which highlights several implications for aviation safety.
