Fatigue risk management

Sleep, the body clock and the WOCL; ICAO, EASA ORO.FTL and FAA Part 117 limits; FRMS, rostering, controlled rest and maintenance shift fatigue

By Aerospace Garage Desk · Practitioner · 45 minutes · 24 narrated pages

What you will be able to do

  • ✓ Explain how sleep loss, extended wakefulness, the body clock and time-zone changes produce fatigue, and why the window of circadian low matters.
  • ✓ Apply the ICAO framework and the EASA ORO.FTL and FAA Part 117 prescriptive limits to calculate flight duty periods, extensions, rest and cumulative limits.
  • ✓ Review rosters for disruptive duties, WOCL encroachment, acclimatisation and recovery rest, and correct a roster that is legal but unsafe.
  • ✓ Describe the four components of a fatigue risk management system, the proper use of bio-mathematical models, and how to triage a fatigue report in a just culture.
  • ✓ Apply practical countermeasures, including controlled rest and maintenance shift planning under Part-145, using the official findings on Air Canada Flight 878.
