What is the minimum rest requirement prior to RAP or FDP and the associated sleep opportunity?

• A. 6 hours; 8 hours
• B. 10 hours; 12 hours
• C. 8 hours; 10 hours
• D. 4 hours; 6 hours

Answer: (C)

Fatigue management focuses on ensuring pilots have enough recoverable rest before starting a RAP or FDP. The required minimum rest is eight hours, and there must be a sleep opportunity of ten hours. The eight hours give the crew a baseline period to recover from prior duty, while the ten-hour window provides enough time to actually sleep, accounting for time to fall asleep and possible awakenings. This setup supports obtaining sufficient restorative sleep despite circadian factors or pre-duty tasks, helping to reduce fatigue risk during the RAP or FDP. Shorter rest periods would not provide enough recovery, and longer windows are not the stated requirement.
