What is the maximum flight time allowed in 672 consecutive hours?

• A. 50 hours
• B. 75 hours
• C. 100 hours
• D. 125 hours

Answer: (C)

This question tests how flight-time limits are applied over a rolling 672-hour window, which spans 28 days. Within that period, the maximum amount of time a pilot may be in the cockpit flying is 100 hours. So the choice that equals 100 hours is the correct ceiling because it matches this fatigue-management limit. The other numbers don’t fit: 50 and 75 hours are below the allowed maximum, and 125 hours would exceed the limit for the 28-day window. Understanding this helps you see how flight-time rules balance operational needs with rest and safety.
