FAA Airline Transport Pilot (ATM)Regulations (14 CFR 117/121/61)Medium
Under 14 CFR Part 117, what is the maximum total flight time a flightcrew member may accumulate in any 365 consecutive calendar days?
- A1,200 hours
- B100 hours
- C900 hours
- D1,000 hours
Show answer & explanationAnswer & explanation
Correct answer: D. 1,000 hours
14 CFR 117.23 limits flight time to 1,000 hours in any 365 consecutive calendar days, in addition to the 100-hour limit in any 672 consecutive hours (28 days).
Why the other options are wrong
- A. 1,200 hours exceeds the regulatory cap.
- B. 100 hours is the 28-day (672-hour) limit, not the annual limit.
- C. 900 hours is not a Part 117 limit.
Part 117 Cumulative Flight Time Limits
14 CFR 117.23 sets caps on flight time over rolling 28-day and 365-day periods to prevent cumulative fatigue.
- 100 hours max in any 672 consecutive hours (28 days)
- 1,000 hours max in any 365 consecutive days
- Limits apply regardless of duty type or augmentation status
Memory trick: "100 in a month, 1,000 in a year."
