Aircraft Takeoff Calculator
Calculate Takeoff Distance
This takeoff calculator provides an estimation of the ground roll distance required for an aircraft to become airborne. Enter the aircraft and environmental parameters below.
Total weight of the aircraft at takeoff, in kilograms (kg).
Please enter a valid positive number.
The total surface area of the wings, in square meters (m²).
Please enter a valid positive number.
Density of the air, in kilograms per cubic meter (kg/m³). Standard sea level is 1.225.
Please enter a valid positive number.
The total forward force produced by the engine(s), in Newtons (N).
Please enter a valid positive number.
The maximum lift coefficient, a dimensionless number determined by the airfoil and flap setting.
Please enter a valid positive number.
The drag coefficient during ground roll. Includes effects of gear, flaps, and ground effect.
Please enter a valid positive number.
Coefficient of rolling friction. (e.g., 0.02 for asphalt, 0.05 for short grass)
Please enter a valid positive number.
Estimated Takeoff Ground Roll
— m
Stall Speed (V_stall)
— m/s
Takeoff Speed (V_TO)
— m/s
Net Acceleration
— m/s²
Formula Used: The takeoff distance is estimated using the formula: Distance = V_TO² / (2 * a), where V_TO is the takeoff speed (typically 1.1 * Stall Speed) and ‘a’ is the net acceleration. Acceleration is calculated from the net force (Thrust – Drag – Rolling Friction) divided by the aircraft’s mass.
