Fatigue Risk Assessment of Cabin Crew for Aviation Transport Safety

Abstract

Airlines recognize fatigue as a threat to flight safety. Fatigue risk management (FRM) is crucial to maximizing safety levels. FRM necessitates measuring and assessing fatigue, sleep, and workload to identify risks, and to determine associated risk indicators, risk severity, risk probability, and risk level. This research evaluates the causes of fatigue and their risks in order to develop an effective fatigue risk assessment system for aviation cabin crew, in collaboration with four commercial airlines. The bowtie method is used to assess fatigue causes, risk identification, and management strategies. This study identifies fatigue causes and risk-related components for developing a practical fatigue risk assessment tool for the aviation cabin crew.
