Estimated Fuel Consumption

Rough trip fuel from flight time, burn rate and reserve percentage.

Calculations run locally in your browser; nothing is sent to a server.

Formula and method

Fuel = block time × burn rate × (1 + reserve %). Litres = kg ÷ 0.8 kg/L (typical Jet A-1).

Assumptions

Burn rate is an input you supply, not a manufacturer figure. Real fuel planning follows operator procedures and regulations (alternate, final reserve, contingency) and depends on weight, altitude and weather. Use for education only.

Worked example

7 h × 2,500 kg/h + 5 % = 18,375 kg ≈ 22,969 L.
