what is Take Off Ground Run?

A takeoff ground run, also known as a take-off roll or ground roll, is the distance an aircraft travels from the beginning of its takeoff to the point when it leaves the ground or water. It's the portion of the takeoff procedure where the aircraft accelerates from a standstill to an airspeed that provides enough lift to become airborne.

How to Calculate Take Off Ground Run?

Take Off Ground Run calculator uses Takeoff Ground Run = Weight Of Aircraft/(2*[g])*int((2*Velocity of Aircraft)/(Thrust Force-Drag Force-Reference Of Rolling Resistance Coefficient*(Weight Of Aircraft-Lift Force)),x,0,Aircraft Lift Off Speed) to calculate the Takeoff Ground Run, Take Off Ground Run is a measure of the distance required by an aircraft to take off from a standstill to lift-off, considering the aircraft's weight, aerodynamics, thrust, drag, and rolling resistance, it represents the ground run required to build up sufficient speed for the aircraft to lift off the ground, ensuring a safe takeoff. Takeoff Ground Run is denoted by S_g symbol.

How to calculate Take Off Ground Run using this online calculator? To use this online calculator for Take Off Ground Run, enter Weight Of Aircraft (W_aircraft), Velocity of Aircraft (V_∞), Thrust Force (N), Drag Force (D), Reference Of Rolling Resistance Coefficient (μ_ref), Lift Force (L) & Aircraft Lift Off Speed (V_LOS) and hit the calculate button. Here is how the Take Off Ground Run calculation can be explained with given input values -> 239.3769 = 2000/(2*[g])*int((2*292)/(20000-65-0.004*(2000-7)),x,0,80.11).
