Crew Fatigue Safety Performance Indicators for Fatigue Risk Management Systems

The use of Fatigue Risk Management Systems (FRMS) is gaining momentum in the airline industry. The International Civil Aviation Organization (ICAO) defines FRMS as "a data-driven means of continuously monitoring and managing fatigue-related safety risks, based upon scientific principles and knowledge as well as operational experience that ensures relevant personnel are performing at adequate levels of alertness". A challenge to implementation of FRMS is a lack of agreed-upon safety performance indicators (SPIs). A core set of SPIs are proposed in this paper as a starting point. The SPIs are based on measures of crewmembers' prior sleep, performance, and subjective fatigue and sleepiness at different phases of the flight. Methods for interpreting and comparing SPIs on different flights are also proposed. Data from 220 long-range and ultra-long-range flights involving three airlines and 133 landing crewmembers were used to illustrate the proposals.
