What is the average flying time per fuel load of a helicopter?

The average flying time per fuel load of a helicopter is commonly understood to be between one and a half to two hours. This timeframe takes into account the typical operational parameters of helicopters, including the capacity of their fuel tanks, the efficiency of their engines, and the demands of various flight missions.

Helicopters are designed to perform versatile and often short-duration flights, but the average operational time reflects the need for a balance between range and maneuverability. Hence, this range of one and a half to two hours is practical for most helicopters used in civilian, military, and search-and-rescue operations. This allows for effective mission planning, providing adequate time for operations before considerations for fuel management become critical.

The other options, such as one hour, two and a half to three hours, or thirty minutes, do not accurately represent the typical fuel consumption and flying duration metrics observed in helicopter operations.
