Trip Fuel Calculator

Estimate trip fuel required using fuel flow and trip time. This free aviation calculator helps pilots plan the enroute fuel needed for a flight.

Calculate Trip Fuel

Enter fuel flow and trip time to calculate the estimated trip fuel required in gallons.

Trip Fuel Calculator

How It Works

Trip Fuel:
Trip Fuel = Fuel Flow × Trip Time

This calculator estimates the fuel required for the planned trip segment only.

Example:
10 gallons per hour × 2.5 hours = 25 gallons

What Is Trip Fuel?

Trip fuel is the fuel expected to be used during the planned enroute portion of a flight. It is one of the core fuel planning values used before adding alternate fuel, holding fuel, and reserve fuel.

Accurate trip fuel planning helps pilots estimate fuel required for the expected route and avoid underestimating total fuel needs.

Why Pilots Use a Trip Fuel Calculator

Trip Fuel FAQ

Does trip fuel include reserve fuel?

No. Trip fuel is normally planned separately from reserve fuel.

Does trip fuel include alternate fuel?

No. Alternate fuel is usually planned separately from trip fuel.

What fuel flow should I use?

Use a realistic expected fuel flow for the trip segment based on aircraft configuration, altitude, winds, mixture, and power setting.

Why is trip fuel important?

Trip fuel is one of the core pieces of fuel planning and helps pilots estimate how much fuel the planned route itself will require.
