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. Jeppesen also recently released CrewAlert, an iPhone app that shows how sleep science applies to crew schedules. CrewAlert allows for data, collected in actual operations, to be fed back into an operator’s fatigue risk management system for purposes of correlation with other pilot data and further refinement of the FRM model. Data generated by an FRM assessment, including alertness and risk information, is processed by Jeppesen crew planning optimization software when generating crew pairings and rosters for operators. This data is also available to crew planners to control and monitor fatigue risk during manual roster maintenance and day-of-operation changes.
