Use this calculator for flight-planning study or a first-pass cross-check when all inputs describe the same aircraft, atmospheric condition, and phase of flight.

Flight time (h)

Duration of the flight.

Fuel flow (L/h)

Fuel consumption rate.

Compute the fuel burned over a flight from the hourly consumption rate. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Fuel burned (L)

Total fuel burned.

• Do not use a generic calculator in place of the current aircraft flight manual, approved performance data, operating limitations, NOTAMs, weather, or regulations. Real performance changes with configuration, runway condition, altitude, temperature, wind, loading, and technique.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Cross-check the result against the aircraft flight manual or approved planning system, then apply the required safety margins. Keep signed wind, heading, altitude, speed, and fuel conventions explicit.

• Taxi Fuel Calculator

  Compute the fuel burned during taxi from the ground burn rate and taxi time.

• Endurance Calculator

  Compute how long the usable fuel lasts at a given consumption rate.

• Estimated Trip Fuel Calculator

  Estimate the fuel needed for a trip from distance, ground speed, and fuel burn rate.
