How to Calculate Touchdown velocity?
Touchdown velocity calculator uses Touchdown Velocity = 1.3*(sqrt(2*Weight Newton/(Freestream density*Reference Area*Maximum Lift Coefficient))) to calculate the Touchdown Velocity, The Touchdown velocity refers to the speed at which an aircraft makes contact with the runway during the landing phase of a flight, it is the velocity component along the direction of the runway at the moment the aircraft's wheels touch the ground. Touchdown Velocity is denoted by VT symbol.
How to calculate Touchdown velocity using this online calculator? To use this online calculator for Touchdown velocity, enter Weight Newton (W), Freestream density (ρ∞), Reference Area (S) & Maximum Lift Coefficient (CL,max) and hit the calculate button. Here is how the Touchdown velocity calculation can be explained with given input values -> 4.456759 = 1.3*(sqrt(2*60.34/(1.225*5.08*1.65))).
