What is the endurance of the HH-65 Dolphin?

• A. 3 hours
• B. 2 hours
• C. 4 hours
• D. 5 hours

Answer: (A)

Endurance is the maximum time the helicopter can stay airborne on a full fuel load with the required reserves. For the HH-65 Dolphin, the standard fuel capacity and mission planning give about three hours of flight time. This value assumes typical weight, altitude, and power settings, and it can vary with conditions, but three hours is the published endurance for a standard mission. Shorter durations would imply less fuel or stricter reserves, while longer durations would exceed the aircraft’s standard fuel capacity unless extra fuel is carried.
