Calculate fuel economy, burn rate, flight time, distance or ground speed with selectable units. These are constant-average arithmetic estimates; reserves, taxi, climb and wind effects are not added. The optional R44 Raven II illustration uses approximate operator averages of 15 US gal/h and 110 kt in still air, as reported by Toran Heli Services. Unsupported Bell 206, H125 and S-76 defaults have been removed; use approved aircraft data.

Arithmetic estimate with constant average burn and ground speed. Use approved aircraft data; reserves, taxi, climb and wind effects are not added.

Helicopter Fuel Consumption Formula

The following two example problems outline the steps and information needed to calculate the Helicopter Fuel Consumption.

HFC = MF / FU

Variables:

  • HFC is the fuel economy (miles per US gallon)
  • MF is the total miles flown 
  • FU is the total fuel used (US gallons) 

How to Calculate Helicopter Fuel Consumption?

The following steps outline how to calculate the Helicopter Fuel Consumption.

  1. First, determine the total miles flown. 
  2. Next, determine the total fuel used (gallons). 
  3. Next, gather the formula from above = HFC = MF / FU.
  4. Finally, calculate the Helicopter Fuel Consumption.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

total miles flown = 500

total fuel used (US gallons) = 100

HFC = MF / FU = 500 / 100 = 5 miles per US gallon
