Abstract

In commercial aviation, safety is of paramount importance and an indispensable prerequisite for building extensive, dependable air transportation networks. Several aspects affect airline safety, from training to operations and organizational conditions. The critical importance of aircrew fatigue has long been identified; in 2016, nearly 20% of all accidents under investigation by the US NTSB had it listed as one of the probable causes or contributing factors. This study aims to evaluate the utility of adding psychological fatigue elements to the fatigue self-report and survey tools currently used by airlines. Research goals include identifying psychological fatigue markers in airline fatigue survey forms, analyzing these instruments to determine their sensitivity in identifying fatigue that is not exclusively attributed to physiological factors, and investigating potential improvements of these instruments for use in commercial aviation. The authors examined the effect of psychological and physiological fatigue factors on the aviation industry's overall state and dynamics, especially given the consequences of the recent pandemic. Analysis indicates that incorporating psychological items to existing fatigue reporting and survey instruments significantly changes the measured fatigue levels, suggesting that measuring physiological fatigue alone may not be sufficient to accurately determine overall fatigue levels. The proposed implementation of psychological Fatigue Indicators identifies critical and significant risks related to the current Fatigue Risk Management System, especially in atypical periods when the aviation industry is experiencing substantial disruptions and psychological fatigue is prevalent.
