Flight Safety Notice

Pilot fatigue is a critical aviation safety concern. This calculator helps optimize rest periods and comply with FAR Part 117, but does not replace FAA regulations, company policy, or professional judgment. If you are too fatigued to fly safely, report this to your chief pilot or flight operations immediately. Passenger and crew safety depends on well-rested pilots.

It is not a substitute for FAA regulations (FAR Part 117), company fatigue risk management systems (FRMS), or professional judgment. The recommendations are based on FAA duty time rules, NASA sleep research, and aviation fatigue science. If you feel too fatigued to operate safely, you have the right and responsibility to report yourself unfit for duty. Compliance with FAR Part 117 does not guarantee you are adequately rested. Always prioritize flight safety. Contact your chief pilot, flight operations, or union safety committee with fatigue concerns.
