Liftoff Velocity Given By Weight Calculator

Liftoff velocity, crucial in flight mechanics, is the minimum speed an aircraft needs to become airborne. Determined by the balance of lift and weight forces, it depends on factors such as aircraft design, weight, engine thrust, and takeoff configuration. Achieving liftoff velocity ensures the aircraft overcomes gravity and begins a controlled ascent. The formula to calculate Liftoff velocity is as follows:

Where:

  • W is the weight in N.
  • S is the Wing area in m2.
  • CLmax is the Maximum Lift Coefficient.
