Jeppesen added fatigue risk management (FRM) functionality to its Crew Management System suite, furthering its work to prevent and mitigate fatigue risk in crew planning and operation. According to the company, the FRM solution takes into consideration crewmembers’ predicted levels of fatigue when generating and maintaining crew schedules. Predictions of crew alertness and fatigue risk are based on the Boeing alertness model, a bio-mathematical model developed jointly by Jeppesen and parent company Boeing.
