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.

Transit fuel (kg)

Fuel needed to reach the recovery point.

Reserve fuel (kg)

Fuel to keep in reserve at arrival.

Compute the bingo fuel state by adding the transit requirement to the reserve. 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]

Bingo fuel (kg)

Minimum fuel state before diverting immediately.

• 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.

• Joker Fuel Calculator

  Compute the joker fuel state by adding a planned margin to the bingo fuel.

• Basic Block Fuel Subtotal Calculator

  Sum taxi, trip, contingency, and final-reserve components into a basic block-fuel subtotal; other required fuel may still apply.

• Block Fuel Calculator

  Sum trip, contingency, alternate, final reserve, and taxi fuel into the total block fuel.
