Operating Empty Weight Solution

STEP 0: Pre-Calculation Summary

Formula Used

Operating Empty Weight = Gross Weight-Useful Weight
W_E = W_G-W_U
This formula uses 3 Variables

Variables Used

Operating Empty Weight - (Measured in Kilogram) - Operating Empty Weight is the sum of the empty weight and the crew plus their baggage.
Gross Weight - (Measured in Kilogram) - Gross Weight of Aircraft refers to the total weight of an aircraft, including its structure, payload (such as passengers, cargo, and fuel), and any additional equipment or provisions.
Useful Weight - (Measured in Kilogram) - Useful Weight refers to the portion of the aircraft's total weight that is available for carrying payload, passengers, and cargo, excluding the weight of the structure and essential equipment.

STEP 1: Convert Input(s) to Base Unit

Gross Weight: 16755 Kilogram --> 16755 Kilogram No Conversion Required
Useful Weight: 7865 Kilogram --> 7865 Kilogram No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

W_E = W_G-W_U --> 16755-7865

Evaluating ... ...

W_E = 8890

STEP 3: Convert Result to Output's Unit

8890 Kilogram --> No Conversion Required

FINAL ANSWER

8890 Kilogram <-- Operating Empty 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

Operating Empty Weight Formula

Operating Empty Weight = Gross Weight-Useful Weight
W_E = W_G-W_U

what is operating empty weight?

Basic Operating Weight (BOW) Total weight of the aircraft, including crew, ready for flight, but without payload or fuel (sometimes excludes the crew). Includes all fixed ballast, unusable fuel, normal operating level of oil and total quantity of hydraulic fluid (transport aircraft only).

How to Calculate Operating Empty Weight?

Operating Empty Weight calculator uses Operating Empty Weight = Gross Weight-Useful Weight to calculate the Operating Empty Weight, The Operating Empty Weight (OEW) of an aircraft refers to its weight when it is empty of passengers, cargo, and fuel, but includes the weight of the crew, any operational items, and basic equipment necessary for flight. Operating Empty Weight is denoted by W_E symbol.

How to calculate Operating Empty Weight using this online calculator? To use this online calculator for Operating Empty Weight, enter Gross Weight (W_G) & Useful Weight (W_U) and hit the calculate button. Here is how the Operating Empty Weight calculation can be explained with given input values -> 6345 = 16755-7865.

FAQ

What is Operating Empty Weight?

The Operating Empty Weight (OEW) of an aircraft refers to its weight when it is empty of passengers, cargo, and fuel, but includes the weight of the crew, any operational items, and basic equipment necessary for flight and is represented as W_E = W_G-W_U or Operating Empty Weight = Gross Weight-Useful Weight. Gross Weight of Aircraft refers to the total weight of an aircraft, including its structure, payload (such as passengers, cargo, and fuel), and any additional equipment or provisions & Useful Weight refers to the portion of the aircraft's total weight that is available for carrying payload, passengers, and cargo, excluding the weight of the structure and essential equipment.

How to calculate Operating Empty Weight?

The Operating Empty Weight (OEW) of an aircraft refers to its weight when it is empty of passengers, cargo, and fuel, but includes the weight of the crew, any operational items, and basic equipment necessary for flight is calculated using Operating Empty Weight = Gross Weight-Useful Weight. To calculate Operating Empty Weight, you need Gross Weight (W_G) & Useful Weight (W_U). With our tool, you need to enter the respective value for Gross Weight & Useful Weight 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 Operating Empty Weight?

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

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