How much fuel does the heater burn per hour?

The correct answer indicates that the heater burns ½ gallon of fuel per hour. This figure is often based on typical operational data and specifications for many aircraft heaters used in multi-engine aircraft.

In flight operations, knowing the fuel consumption rate of the heater is crucial for flight planning, particularly in cold weather operations where cabin heating is necessary. A consumption rate of ½ gallon per hour allows pilots to accurately account for this fuel usage when calculating total fuel consumption and weight limits. By understanding the specific fuel usage of different systems on the aircraft, pilots can optimize performance and maintain safety margins throughout the flight.

This fuel burn rate can vary based on individual heaters and their operational settings, but recognizing that ½ gallon is a common value helps pilots to effectively plan their fuel needs during multi-engine operations.
