FAA Airline Transport Pilot (ATM)Regulations (14 CFR 117/121/61)Medium
Under 14 CFR Part 117, what minimum rest period must a certificate holder provide a flightcrew member immediately before the start of a flight duty period?
- A12 consecutive hours regardless of circumstances
- B9 consecutive hours
- C8 consecutive hours with no sleep opportunity requirement
- D10 consecutive hours, including an opportunity for 8 hours of uninterrupted sleep
Show answer & explanationAnswer & explanation
Correct answer: D. 10 consecutive hours, including an opportunity for 8 hours of uninterrupted sleep
14 CFR 117.25 requires a minimum rest period of at least 10 consecutive hours prior to the start of an FDP, and that rest period must provide the flightcrew member an opportunity for at least 8 hours of uninterrupted sleep.
Why the other options are wrong
- A. 12 hours is not the baseline minimum, though longer rest may sometimes be needed.
- B. 9 hours is not a value used in Part 117 rest rules.
- C. 8 hours alone is the sleep opportunity, not the full rest period.
Part 117 Minimum Rest Period
The minimum time off duty required before a flightcrew member may begin a flight duty period.
- Minimum 10 consecutive hours before FDP begins
- Must include opportunity for 8 hours uninterrupted sleep
- Rest period begins when free from all duty and transportation to lodging
Memory trick: "10 to rest, 8 to sleep."
