Desired Take off Weight Solution

STEP 0: Pre-Calculation Summary

Formula Used

Desired Takeoff Weight of Aircraft = Payload Carried+Operating Empty Weight+Fuel Weight to be carried
D = PYL+OEW+FW
This formula uses 4 Variables

Variables Used

Desired Takeoff Weight of Aircraft - (Measured in Tonne) - Desired Takeoff Weight of Aircraft is the weight of the aircraft.
Payload Carried - (Measured in Tonne) - Payload Carried (passengers and cargo), Payload is the object or the entity which is being carried by an aircraft or a launch vehicle.
Operating Empty Weight - (Measured in Tonne) - Operating Empty Weight of the Aircraft, The empty weight of an aircraft is the weight of the aircraft without including passengers, baggage, or fuel.
Fuel Weight to be carried - (Measured in Tonne) - Fuel Weight to be carried is defined as the total mass of the fuel to be carried (usually includes reserve fuel).

STEP 1: Convert Input(s) to Base Unit

Payload Carried: 25 Tonne --> 25 Tonne No Conversion Required
Operating Empty Weight: 10 Tonne --> 10 Tonne No Conversion Required
Fuel Weight to be carried: 1.1 Tonne --> 1.1 Tonne No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

D = PYL+OEW+FW --> 25+10+1.1

Evaluating ... ...

D = 36.1

STEP 3: Convert Result to Output's Unit

36100 Kilogram -->36.1 Tonne (Check conversion here)

FINAL ANSWER

36.1 Tonne <-- Desired Takeoff Weight of Aircraft

Lifting Force given Friction Force due to Rolling Resistance

Go Lifting Force of Aircraft = (((Mass Aircraft*[g]*cos(Angle between Runway and Horizontal Plane))-(Force of Friction/Coefficient of Rolling Friction)))

Vehicle Speed for Lifting Force Provided by Wing Body of Vehicle

Go Vehicle Speed = sqrt((Lifting Force of Aircraft/(0.5*Density Altitude for flying*Aircraft Gross Wing Area*Lift Coefficient)))

Lift Coefficient for Lifting Force Provided by Wing Body of Vehicle

Go Lift Coefficient = Lifting Force of Aircraft/(0.5*Density Altitude for flying*(Vehicle Speed^2)*Aircraft Gross Wing Area)

Lifting Force Provided by Wing Body of Vehicle

Go Lifting Force of Aircraft = 0.5*Density Altitude for flying*Vehicle Speed^2*Aircraft Gross Wing Area*Lift Coefficient

Operating Empty Weight when Desired Take-off Weight is considered

Go Operating Empty Weight = Desired Takeoff Weight of Aircraft-Payload Carried-Fuel Weight to be carried

Payload carried when desired take-off weight is considered

Go Payload Carried = Desired Takeoff Weight of Aircraft-Operating Empty Weight-Fuel Weight to be carried

Fuel Weight to be Carried given Desired Takeoff Weight

Go Fuel Weight to be carried = Desired Takeoff Weight of Aircraft-Payload Carried-Operating Empty Weight

Desired Take off Weight

Go Desired Takeoff Weight of Aircraft = Payload Carried+Operating Empty Weight+Fuel Weight to be carried

True Mach number when true aircraft speed

Go True Mach Number = True Aircraft Speed/Speed of Sound

True Aircraft Speed (Mach number)

Go True Aircraft Speed = Speed of Sound*True Mach Number

Speed of Sound (Mach number)

Go Speed of Sound = True Aircraft Speed/True Mach Number

Desired Take off Weight Formula

Desired Takeoff Weight of Aircraft = Payload Carried+Operating Empty Weight+Fuel Weight to be carried
D = PYL+OEW+FW

What is Maximum Structural Payload Weight ?

Maximum Structural Payload Weight (or mass) is the maximum demonstrated payload to be carried without stressing the aircraft fuselage. Maximum zero fuel weight (or mass) is the sum of the operating empty weight and the maximum structural payload weight.

What is maximum takeoff weight?

The maximum takeoff weight or maximum gross takeoff weight or maximum takeoff mass of an aircraft is the maximum weight at which the pilot is allowed to attempt to take off, due to structural or other limits. The analogous term for rockets is gross lift-off mass,

How to Calculate Desired Take off Weight?

Desired Take off Weight calculator uses Desired Takeoff Weight of Aircraft = Payload Carried+Operating Empty Weight+Fuel Weight to be carried to calculate the Desired Takeoff Weight of Aircraft, The Desired Take off Weight (or mass) is the weight of the aircraft considering fuel (includes reserve), payload and OEW to complete a given stage length (trip distance). Desired Takeoff Weight of Aircraft is denoted by D symbol.

How to calculate Desired Take off Weight using this online calculator? To use this online calculator for Desired Take off Weight, enter Payload Carried (PYL), Operating Empty Weight (OEW) & Fuel Weight to be carried (FW) and hit the calculate button. Here is how the Desired Take off Weight calculation can be explained with given input values -> 0.0361 = 25000+10000+1100.

FAQ

What is Desired Take off Weight?

The Desired Take off Weight (or mass) is the weight of the aircraft considering fuel (includes reserve), payload and OEW to complete a given stage length (trip distance) and is represented as D = PYL+OEW+FW or Desired Takeoff Weight of Aircraft = Payload Carried+Operating Empty Weight+Fuel Weight to be carried. Payload Carried (passengers and cargo), Payload is the object or the entity which is being carried by an aircraft or a launch vehicle, Operating Empty Weight of the Aircraft, The empty weight of an aircraft is the weight of the aircraft without including passengers, baggage, or fuel & Fuel Weight to be carried is defined as the total mass of the fuel to be carried (usually includes reserve fuel).

How to calculate Desired Take off Weight?

The Desired Take off Weight (or mass) is the weight of the aircraft considering fuel (includes reserve), payload and OEW to complete a given stage length (trip distance) is calculated using Desired Takeoff Weight of Aircraft = Payload Carried+Operating Empty Weight+Fuel Weight to be carried. To calculate Desired Take off Weight, you need Payload Carried (PYL), Operating Empty Weight (OEW) & Fuel Weight to be carried (FW). With our tool, you need to enter the respective value for Payload Carried, Operating Empty Weight & Fuel Weight to be carried and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
