FAA Airline Transport Pilot (ATM)Regulations (14 CFR 117/121/61)Hard
A Part 121 flightcrew member has just completed a flight duty period (FDP) and is now in a required rest period. During this rest period, the flightcrew member is notified of a schedule change that requires them to report for a new FDP earlier than originally planned. The flightcrew member was offered a Class 1 rest facility but chose to take rest at their personal residence. Assuming the rest period was interrupted, what is the minimum duration of the uninterrupted rest that must be provided to the flightcrew member before the start of the new FDP?
- A12 consecutive hours
- B9 consecutive hours
- C8 consecutive hours
- D10 consecutive hours
Show answer & explanationAnswer & explanation
Correct answer: D. 10 consecutive hours
14 CFR 117.21(c)(1) states that if a flightcrew member's rest period is interrupted by a certificate holder, the certificate holder must provide that flightcrew member with a subsequent uninterrupted rest period equal to the original required rest period. A standard required rest period is 10 consecutive hours (14 CFR 117.25(a)). Thus, the subsequent uninterrupted rest must be 10 hours.
Why the other options are wrong
- A. Incorrect; 12 hours is not a standard required rest period in this context.
- B. Incorrect; 9 hours is not a standard required rest period for this scenario.
- C. Incorrect; 8 hours of sleep opportunity is part of a 10-hour rest, not the total rest.
117.21(c) Interrupted Rest Period
14 CFR 117.21(c) mandates that if a Part 117 required rest period is interrupted by the certificate holder, the flightcrew member must be provided with a subsequent uninterrupted rest period equal to the original required rest period.
- Applies if the certificate holder causes the interruption.
- Subsequent rest period must be uninterrupted.
- Duration of subsequent rest equals original required rest.
- Standard required rest is 10 consecutive hours with 8 hours sleep opportunity.
