Within 168 consecutive hours, how many FDP hours are allowed?

• A. 60
• B. 50
• C. 70
• D. 80

Answer: (A)

The key idea here is fatigue management over a rolling week. In any 168-hour period (that’s seven consecutive days), there is a fixed cap on how many FDP hours you can accumulate. That cap is 60 hours. So the maximum allowed FDP time within a week-long window is 60 hours, which means you can’t exceed that amount in any seven-day block.

Why this makes sense: the limit is designed to prevent excessive duty that could erode rest opportunities and increase fatigue risk. If you tried to push beyond 60 hours in seven days, you’d be going over the safety boundary the rule sets.

The other numbers don’t represent the maximum allowed in that window. A lower figure like 50 would still be permissible, but it’s not the limit you must stay under. Figures like 70 or 80 would violate the seven-day cap, since they exceed what’s allowed in any 168-hour span.
