# Takeoff Velocity Calculator, Formula, Takeoff Velocity Calculation

## Takeoff Velocity Calculator:

Enter the values of Mass of the Aircraft m(kg), Accelaration of Gravity g(m/s2), Coefficient of Lift CL, Surface Area A(m2), Density of the Air d(kg/m3) to determine the value of Takeoff Velocity V(m/s) .

 Enter Mass of the Aircraft: kg Enter Accelaration of Gravity: m/s2 Enter Coefficient of Lift: Enter Surface Area: m2 Enter Density of the Air: kg/m3 Result – Takeoff Velocity: m/s

## Takeoff Velocity Formula:

The Takeoff Velocity V(m/s) in meter per second is equal to the SQRT of the Value of 2 into multiply the Mass of the Aircraft m(kg) in kilogram and Accelaration of gravity g(m/s2) in meter per second square and is Divided by the Coefficient of lift CL is multiply to the Surface Area A(m2) in meter square and Density of the air d(kg/m3) in kilogram per meter cube.

The Equation of Takeoff Velocity can be writtern as,

V(m/s) = SQRT ( 2 * m(kg) * g(m/s2) / ( CL * A(m2) * d(kg/m3) ) )

Here,

V(m/s) = Takeoff Velocity in meter per second

m(kg) = Mass of the Aircraft in kilogram

g(m/s2) = Accelaration of gravity in meter per second square

CL = Coefficient of lift

A(m2) = Surface Area in meter square

d(kg/m3) = Density of the air in kilogram per meter cube

### Takeoff Velocity Calculation :

1)Calculate the Takeoff Velocity and given for Mass of the Aircraft = 3500kg , Coefficient of lift

= .80 , Surface Area = 80m2 , Density of the air = 1.220kg/m3.

V = √( 2 * m * g / ( CL * A * d ))

V = √ ( 2 * 3500 * 9.81 / ( .80 * 80 * 1.220 ) )

V = 29.65m/s.

2)Calculate the Surface Area and given for Mass of the Aircraft = 3500kg , Coefficient of lift

= .80 , Density of the air = 1.220kg/m3 , Takeoff Velocity = 29.65m/s.
