FAA Airline Transport Pilot (ATM)Regulations (14 CFR 117/121/61)Medium
A two-pilot unaugmented Part 121 crew is acclimated and reports for a flight duty period (FDP) beginning at 0800 local time. The trip is scheduled for 4 flight segments. Using the Table B FDP limits in 14 CFR Part 117, what is the maximum FDP permitted?
- A12 hours 30 minutes
- B12 hours 00 minutes
- C11 hours 30 minutes
- D13 hours 00 minutes
Show answer & explanationAnswer & explanation
Correct answer: B. 12 hours 00 minutes
Table B assigns a maximum FDP based on report time and number of segments. For a report time of 0700-1259 with 4 segments, the maximum unaugmented 2-pilot FDP is 12:00. As segments increase from 1-2 (13:00) to 3 (12:30) to 4 (12:00), the allowable FDP steadily decreases.
Why the other options are wrong
- A. 12:30 applies to 3 segments, not 4.
- C. 11:30 corresponds to 5 segments in this window.
- D. 13:00 applies only to 1-2 segments in this reporting window.
Part 117 Table B FDP Limits
Table B in 14 CFR Part 117 sets maximum flight duty periods for unaugmented 2-pilot crews based on acclimated report time and number of flight segments.
- FDP limits decrease as report time moves into circadian low periods
- FDP limits decrease as number of scheduled segments increases
- 0700-1259 report window allows 13:00 for 1-2 legs down to 10:00 for 8+ legs
Memory trick: "More legs, less time in the air-chair."
