Zero fuel weight given mission fuel, reserve and take off weight Solution

STEP 0: Pre-Calculation Summary

Formula Used

Zero Fuel Weight = Takeoff Weight-Fuel Load-Reserve Fuel
W_ZF = W_TO-W_f-W_RF
This formula uses 4 Variables

Variables Used

Zero Fuel Weight - (Measured in Kilogram) - Zero fuel weight (ZFW) is the weight of the aircraft with payload on board and empty fuel tanks.
Takeoff Weight - (Measured in Kilogram) - Takeoff Weight is the total weight of the aircraft during take-off.
Fuel Load - (Measured in Kilogram) - Fuel load may be available fuel (consumable fuel) or total fuel and is usually dry weight.
Reserve Fuel - (Measured in Kilogram) - Reserve fuel is the extra fuel for maneuvering, holding, aborting the landing and making a diversion flight.

STEP 1: Convert Input(s) to Base Unit

Takeoff Weight: 45000 Kilogram --> 45000 Kilogram No Conversion Required
Fuel Load: 28244 Kilogram --> 28244 Kilogram No Conversion Required
Reserve Fuel: 1000 Kilogram --> 1000 Kilogram No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

W_ZF = W_TO-W_f-W_RF --> 45000-28244-1000

Evaluating ... ...

W_ZF = 15756

STEP 3: Convert Result to Output's Unit

15756 Kilogram --> No Conversion Required

FINAL ANSWER

15756 Kilogram <-- Zero Fuel Weight

Maximum take off weight

Go Maximum Take Off Weight = Payload/(1-((Operating Empty Weight/Takeoff Weight)+(Fuel Load/Takeoff Weight)))

Operating empty weight from unity equation

Go Operating Empty Weight = Takeoff Weight-(Payload+Fuel Load)

Fuel load from unity equation

Go Fuel Load = Takeoff Weight-(Operating Empty Weight+Payload)

Take off weight from Unity equation

Go Takeoff Weight = Operating Empty Weight+Payload+Fuel Load

Payload weight from Unity equation

Go Payload = Takeoff Weight-Operating Empty Weight-Fuel Load

Zero fuel weight given mission fuel, reserve and take off weight

Go Zero Fuel Weight = Takeoff Weight-Fuel Load-Reserve Fuel

Take off weight given reserve, mission and zero fuel weight

Go Takeoff Weight = Zero Fuel Weight+Reserve Fuel+Fuel Load

Mission fuel given take off, reserve and zero fuel weight

Go Fuel Load = Takeoff Weight-Zero Fuel Weight-Reserve Fuel

Operating empty weight

Go Operating Empty Weight = Gross Weight-Useful Weight

Gross weight

Go Gross Weight = Operating Empty Weight+Useful Weight

Useful load

Go Useful Weight = Gross Weight-Operating Empty Weight

Operating empty weight considering zero fuel weight

Go Operating Empty Weight = Zero Fuel Weight-Payload

Payload of aircraft

Go Payload = Zero Fuel Weight-Operating Empty Weight

Zero fuel weight

Go Zero Fuel Weight = Operating Empty Weight+Payload

Landing weight given zero fuel weight and reserve fuel weight

Go Landing Weight = Zero Fuel Weight+Reserve Fuel

Zero fuel weight given reserve and landing weight

Go Zero Fuel Weight = Landing Weight-Reserve Fuel

Landing weight given take off weight and mission fuel weight

Go Landing Weight = Takeoff Weight-Fuel Load

Zero fuel weight given mission fuel, reserve and take off weight Formula

Zero Fuel Weight = Takeoff Weight-Fuel Load-Reserve Fuel
W_ZF = W_TO-W_f-W_RF

What is the purpose of zero fuel weight?

Zero fuel weight sets a maximum allowable weight that can be carried in the fuselage in order to eliminate the possibility of destructive wing-bending stress.

How to Calculate Zero fuel weight given mission fuel, reserve and take off weight?

Zero fuel weight given mission fuel, reserve and take off weight calculator uses Zero Fuel Weight = Takeoff Weight-Fuel Load-Reserve Fuel to calculate the Zero Fuel Weight, The Zero fuel weight given mission fuel, reserve and take off weight calculation gives you the weight of the aircraft without any fuel, considering both the fuel required for the mission and any additional reserve fuel, the ZFW is an important parameter for weight and balance calculations and operational planning, as it helps ensure that the aircraft remains within its maximum structural limits and meets performance requirements throughout the flight. Zero Fuel Weight is denoted by W_ZF symbol.

How to calculate Zero fuel weight given mission fuel, reserve and take off weight using this online calculator? To use this online calculator for Zero fuel weight given mission fuel, reserve and take off weight, enter Takeoff Weight (W_TO), Fuel Load (W_f) & Reserve Fuel (W_RF) and hit the calculate button.
