Model crew, payload, fuel, oil, and reserves easily. View critical margins and utilization before dispatch. Make balanced loading decisions with fast visuals and exports.
This worked example uses the default values already prefilled in the calculator.
| Parameter | Example Value | Parameter | Example Value |
|---|---|---|---|
| Basic Empty Weight | 8,200.00 kg | Optional Equipment | 180.00 kg |
| Oil Weight | 60.00 kg | Crew Weight | 170.00 kg |
| Passenger Weight | 656.00 kg | Baggage Weight | 126.00 kg |
| Payload Weight | 872.00 kg | Operating Weight | 8,610.00 kg |
| Zero Fuel Weight | 9,482.00 kg | Block Fuel | 996.00 kg |
| Ramp Weight | 10,478.00 kg | Takeoff Weight | 10,433.00 kg |
| Landing Weight | 9,813.00 kg | Landing Fuel | 331.00 kg |
Crew Weight = Crew Count × Average Crew Weight
Passenger Weight = Passenger Count × Average Passenger Weight
Baggage Weight = (Passenger Count × Baggage per Passenger) + Extra Baggage
Payload Weight = Passenger Weight + Baggage Weight + Cargo Weight
Operating Weight = Basic Empty Weight + Optional Equipment + Oil Weight + Crew Weight
Zero Fuel Weight = Operating Weight + Payload Weight
Contingency Fuel = Trip Fuel × (Contingency Percent ÷ 100)
Block Fuel = Taxi Fuel + Trip Fuel + Contingency Fuel + Reserve Fuel + Alternate Fuel
Ramp Weight = Zero Fuel Weight + Block Fuel
Takeoff Weight = Ramp Weight − Taxi Fuel
Landing Weight = Takeoff Weight − Trip Fuel
Landing Fuel Remaining = Takeoff Fuel − Trip Fuel
Useful Load Capacity = Selected Structural Limit − Basic Empty Weight
Zero fuel weight is the aircraft weight without usable fuel. It includes empty weight, crew, oil, passengers, baggage, cargo, and installed optional equipment.
Ramp weight includes all fuel before taxi. Takeoff weight subtracts the taxi fuel expected to burn before brake release and departure roll.
Maximum zero fuel weight protects the airframe from excessive non-fuel structural loading. Fuel may change during flight, but too much payload can overstress the structure before departure.
No. Use the approved manual, actual weighing records, operator procedures, and current loading documents as the final authority. This calculator supports planning and review.
Usually crew is not part of the basic empty weight, but definitions can vary. Match the source definition in your aircraft paperwork and avoid double counting.
Some operators track oil separately during planning. Including oil improves operating weight realism and helps the loading picture better match dispatch conditions.
Reduce payload, adjust fuel planning if operationally valid, add a technical stop, or revise mission assumptions until landing weight falls below the selected limit.
No. Use one unit system consistently. Enter every item and every structural limit in kilograms or in pounds, never a mixture.
