Useful load Solution

STEP 0: Pre-Calculation Summary

Formula Used

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

Variables Used

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.
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.
Operating Empty Weight - (Measured in Kilogram) - Operating empty weight is the sum of the empty weight and the crew plus their baggage.

STEP 1: Convert Input(s) to Base Unit

Gross Weight: 16755 Kilogram --> 16755 Kilogram No Conversion Required
Operating Empty Weight: 8890 Kilogram --> 8890 Kilogram No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

W_U = W_G-W_E --> 16755-8890

Evaluating ... ...

W_U = 7865

STEP 3: Convert Result to Output's Unit

7865 Kilogram --> No Conversion Required

FINAL ANSWER

7865 Kilogram <-- Useful 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

Useful load Formula

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

what is useful load?

The excess of the full load including the crew and passengers, oil and fuel, auxiliary power system, and communication, navigation, and other equipment over the dead weight of an aircraft itself compare dead load.

How to Calculate Useful load?

Useful load calculator uses Useful Weight = Gross Weight-Operating Empty Weight to calculate the Useful Weight, The Useful Load of an aircraft refers to the maximum weight that an aircraft can carry, including passengers, cargo, baggage, crew, and any other items, while still meeting operational and safety requirements, it represents the difference between the Gross Weight of the aircraft and its Operating Empty Weight, which includes the weight of the aircraft structure, engines, systems, and standard equipment. Useful Weight is denoted by W_U symbol.

How to calculate Useful load using this online calculator? To use this online calculator for Useful load, enter Gross Weight (W_G) & Operating Empty Weight (W_E) and hit the calculate button. Here is how the Useful load calculation can be explained with given input values -> 5320 = 16755-8890.

FAQ

What is Useful load?

The Useful Load of an aircraft refers to the maximum weight that an aircraft can carry, including passengers, cargo, baggage, crew, and any other items, while still meeting operational and safety requirements, it represents the difference between the Gross Weight of the aircraft and its Operating Empty Weight, which includes the weight of the aircraft structure, engines, systems, and standard equipment and is represented as W_U = W_G-W_E or Useful Weight = Gross Weight-Operating Empty 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 & Operating empty weight is the sum of the empty weight and the crew plus their baggage.

How to calculate Useful load?

The Useful Load of an aircraft refers to the maximum weight that an aircraft can carry, including passengers, cargo, baggage, crew, and any other items, while still meeting operational and safety requirements, it represents the difference between the Gross Weight of the aircraft and its Operating Empty Weight, which includes the weight of the aircraft structure, engines, systems, and standard equipment is calculated using Useful Weight = Gross Weight-Operating Empty Weight. To calculate Useful load, you need Gross Weight (W_G) & Operating Empty Weight (W_E). With our tool, you need to enter the respective value for Gross Weight & Operating Empty Weight and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
