The Impact of Fatigue and Commuting on Human Performance in Aviation

This presentation explores the role of fatigue in aviation safety, particularly focusing on the experiences of pilots regarding commuting and sleep deprivation. It highlights the circumstances leading to an accident involving two pilots who faced inadequate rest and sleep opportunities, despite prior performance not indicating significant fatigue-related issues. Key fatigue mitigation strategies are discussed, including the need for improved guidance and policies addressing the challenges faced by commuting pilots. Recommendations for enhancing safety and ensuring rested crews are also presented.

Presentation Transcript

  1. Fatigue and Commuting Human Performance presentation

  2. Role of Fatigue - Precursors • Captain • Reduced sleep opportunities • Stayed overnight in crew room • Accessed company computer at 0310 • Accident occurred at normal bedtime • First officer • Overnight transcontinental commute • Slept on airplanes and in crew room

  3. Role of Fatigue - Performance • Performance inconsistent with past reports • Performance not degraded throughout flight, and errors not specific to fatigue • Both pilots likely experiencing some fatigue, but its role in performance cannot be determined

  4. Fatigue Mitigation • Safety recommendations issued addressing fatigue • Most Wanted List since 1990 • Safety Recommendation A-06-10 • FAA has not issued science-based fatigue NPRM • Flight and duty time not issue in this accident

  5. Fatigue and Commuting • Commuting may be necessity • Base closures • Cost of living • All pilots have responsibility to arrive for work rested

  6. Fatigue and Commuting • Most of Colgan’s pilots at EWR commuted • Guidance did not address ways to mitigate fatigue from commuting • same-day commuting not discouraged • crew room policy not enforced • After accident, Colgan revised training and provided fatigue guidance

  7. Fatigue and Commuting • Mitigation strategies include • Providing rest facilities • Identifying affordable accommodations • Planning flight schedules that support commuting
