Zero fuel weight Solution

STEP 0: Pre-Calculation Summary

Formula Used

Zero Fuel Weight = Operating Empty Weight+Payload
W_ZF = W_E+W_P
This formula uses 3 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.
Operating Empty Weight - (Measured in Kilogram) - Operating empty weight is the sum of the empty weight and the crew plus their baggage.
Payload - (Measured in Kilogram) - Payload of a passenger aircraft is the total weight of cargo plus additional passengers being carried in the airplane.

STEP 1: Convert Input(s) to Base Unit

Operating Empty Weight: 8890 Kilogram --> 8890 Kilogram No Conversion Required
Payload: 6866 Kilogram --> 6866 Kilogram No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

W_ZF = W_E+W_P --> 8890+6866

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 Formula

Zero Fuel Weight = Operating Empty Weight+Payload
W_ZF = W_E+W_P

what is the zero fuel weight?

For the purposes of this part, maximum zero fuel weight means the maximum permissible weight of an airplane with no disposable fuel or oil. The zero fuel weight figure may be found in either the airplane type certificate data sheet or the approved Airplane Flight Manual, or both.

How to Calculate Zero fuel weight?

Zero fuel weight calculator uses Zero Fuel Weight = Operating Empty Weight+Payload to calculate the Zero Fuel Weight, The Zero Fuel Weight (ZFW) of an aircraft is the total weight of the aircraft excluding any fuel, it represents the combined weight of all operational items such as passengers, cargo, crew, equipment, and any other items on board, but without the weight of the fuel itself, to calculate the Zero Fuel Weight, you would typically subtract the total fuel weight from the takeoff weight of the aircraft. Zero Fuel Weight is denoted by W_ZF symbol.

How to calculate Zero fuel weight using this online calculator? To use this online calculator for Zero fuel weight, enter Operating Empty Weight (W_E) & Payload (W_P) and hit the calculate button. Here is how the Zero fuel weight calculation can be explained with given input values -> 16756 = 8890+6866.

FAQ

What is Zero fuel weight?

The Zero Fuel Weight (ZFW) of an aircraft is the total weight of the aircraft excluding any fuel, it represents the combined weight of all operational items such as passengers, cargo, crew, equipment, and any other items on board, but without the weight of the fuel itself, to calculate the Zero Fuel Weight, you would typically subtract the total fuel weight from the takeoff weight of the aircraft and is represented as W_ZF = W_E+W_P or Zero Fuel Weight = Operating Empty Weight+Payload. Operating empty weight is the sum of the empty weight and the crew plus their baggage & Payload of a passenger aircraft is the total weight of cargo plus additional passengers being carried in the airplane.

How to calculate Zero fuel weight?

The Zero Fuel Weight (ZFW) of an aircraft is the total weight of the aircraft excluding any fuel, it represents the combined weight of all operational items such as passengers, cargo, crew, equipment, and any other items on board, but without the weight of the fuel itself, to calculate the Zero Fuel Weight, you would typically subtract the total fuel weight from the takeoff weight of the aircraft is calculated using Zero Fuel Weight = Operating Empty Weight+Payload. To calculate Zero fuel weight, you need Operating Empty Weight (W_E) & Payload (W_P). With our tool, you need to enter the respective value for Operating Empty Weight & Payload and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.

How many ways are there to calculate Zero Fuel Weight?

In this formula, Zero Fuel Weight uses Operating Empty Weight & Payload. We can use 2 other way(s) to calculate the same, which is/are as follows -

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