FAA Aircraft Dispatcher (ADX)Regulations (Part 121)Medium
A Part 121 domestic air carrier schedules a flight with two pilots and no augmented crew. Under 14 CFR 121.471, what is the maximum scheduled flight time permitted for these pilots in any 24 consecutive hours without a required rest period?
- A14 hours
- B8 hours
- C10 hours
- D12 hours
Show answer & explanationAnswer & explanation
Correct answer: B. 8 hours
14 CFR 121.471(a) limits scheduled flight time for domestic operations with a two-pilot unaugmented crew to 8 hours within any 24 consecutive hours, unless additional rest or an augmented crew is provided. This ensures pilots are not scheduled beyond fatigue-safe limits.
Why the other options are wrong
- A. 14 hours far exceeds any Part 121 domestic flight time limit for two pilots.
- C. 10 hours exceeds the unaugmented crew limit for domestic operations.
- D. 12 hours would require crew augmentation, not applicable here.
Domestic Flight Time Limits (121.471)
Regulation limiting scheduled flight time for domestic Part 121 pilots based on crew size and rest facilities.
- 8 hours max for 2-pilot unaugmented crew in 24 hrs
- 100 hours per calendar month, 1,000 hours per calendar year limits also apply
- Augmented crews allow longer flight time with rest facilities
Memory trick: Two pilots, eight hours — no more without a rest, no less.
