Which statement describes the fatigue-management period in crew scheduling?

• A. Flight time
• B. Flight duty period
• C. Rest period
• D. Duty time

Answer: (B)

Fatigue management focuses on the time a crew member is on active duty, specifically the window from reporting for duty to being released from duty. This is known as the flight duty period. It’s the period during which fatigue risk must be controlled through limits on how long the crew can be on duty, required rest before and during duties, and related scheduling rules.

Flight time is only the time spent flying the aircraft and doesn’t capture the full on-duty exposure to fatigue. The rest period is the recovery time between duty periods, intended to reduce fatigue, but it isn’t the active duty window being managed. Duty time is the total on-duty span from report to release and includes many activities, but the explicit fatigue-management window used for scheduling safeguards is the flight duty period.
