FDP hour maximums are defined as which combination?

• A. 60 FDP hours in 168 consecutive hours; 190 FDP in 672 consecutive hours
• B. 50 FDP hours in 168 consecutive hours; 180 FDP in 672 consecutive hours
• C. 70 FDP hours in 168 consecutive hours; 200 FDP in 672 consecutive hours
• D. 60 FDP hours in 168 consecutive hours; 170 FDP in 672 consecutive hours

Answer: (A)

FDP hours are the maximum time a flight crew can be scheduled for a flight duty period within rolling time windows to help manage fatigue. The standard limits set a maximum of 60 FDP hours in any 168-hour period (seven days) and 190 FDP hours in any 672-hour period (twenty-eight days). So the correct combination is 60 hours in 168 consecutive hours and 190 hours in 672 consecutive hours. These limits ensure crews aren’t exposed to excessive duty across both short and longer horizons.
