Take off weight from Unity equation Solution

STEP 0: Pre-Calculation Summary

Formula Used

Takeoff Weight = Operating Empty Weight+Payload+Fuel Load
W_TO = W_E+W_P+W_f
This formula uses 4 Variables

Variables Used

Takeoff Weight - (Measured in Kilogram) - Takeoff Weight is the total weight of the aircraft during take-off.
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.
Fuel Load - (Measured in Kilogram) - Fuel load may be available fuel (consumable fuel) or total fuel and is usually dry weight.

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
Fuel Load: 28244 Kilogram --> 28244 Kilogram No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

W_TO = W_E+W_P+W_f --> 8890+6866+28244

Evaluating ... ...

W_TO = 44000

STEP 3: Convert Result to Output's Unit

44000 Kilogram --> No Conversion Required

FINAL ANSWER

44000 Kilogram <-- Takeoff Weight

(Calculation completed in 00.004 seconds)

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

Take off weight from Unity equation Formula

Takeoff Weight = Operating Empty Weight+Payload+Fuel Load
W_TO = W_E+W_P+W_f

What percentage of aircraft weight is fuel?

If the fuel fraction mid-flight for a long-haul jet is 20%. Then that means the thrust required to carry 20% of the weight is 10% of the thrust (if the induced drag equals the form drag at the minimum drag point).

How to Calculate Take off weight from Unity equation?

Take off weight from Unity equation calculator uses Takeoff Weight = Operating Empty Weight+Payload+Fuel Load to calculate the Takeoff Weight, The Take off weight from Unity equation formula is defined as which is the total weight of the aircraft, including all operational items such as passengers, cargo, crew, fuel, and any other items on board, at the moment of takeoff it is calculated calculated by summing up the operating empty weight, payload weight , and fuel load. Takeoff Weight is denoted by W_TO symbol.

How to calculate Take off weight from Unity equation using this online calculator? To use this online calculator for Take off weight from Unity equation, enter Operating Empty Weight (W_E), Payload (W_P) & Fuel Load (W_f) and hit the calculate button. Here is how the Take off weight from Unity equation calculation can be explained with given input values -> 45000 = 8890+6866+28244.

FAQ

What is Take off weight from Unity equation?

The Take off weight from Unity equation formula is defined as which is the total weight of the aircraft, including all operational items such as passengers, cargo, crew, fuel, and any other items on board, at the moment of takeoff it is calculated calculated by summing up the operating empty weight, payload weight , and fuel load and is represented as W_TO = W_E+W_P+W_f or Takeoff Weight = Operating Empty Weight+Payload+Fuel Load.
