Abstract:

In order to reduce fatigue for international flight crews and establish the Fatigue Risk Management System (FRMS), multi-modal individual alertness and fatigue evaluation were used to study the fatigue level of international flight crews. The sleep conditions of international flight crews in the east-west direction were collected by sleep monition bracelets. The Karolinska Sleepiness Scale (KSS), Samn-Perelli Fatigue Scale (SP) and Continuous Performance Test (CPT) were used to measure crew alertness in different flight phases. Also, the consistency of the biomathematical fatigue prediction model System for Aircrew Fatigue Evaluation (SAFE) and the actual operating results were compared and verified. The study shows that the subjective fatigue of the crews flying from west to east is higher than that of the crews flying from east to west, and their sleep duration is shorter and more fragmented. The alertness of the crew decreases after the take-off mission, and the SAFE fatigue prediction results have a significant correlation with data from China's operating environment.
