The lift off distance is the distance along the centre of the runway between the starting point and A. End of the runway B. End of stop-way C. Point where air craft becomes air borne D. Point where air craft attains a height of 10.7 m

The correct answer is C. Point where air craft becomes air borne.

The lift-off distance is the distance along the centerline of the runway between the start of the takeoff roll and the point where the airplane becomes airborne. It is a function of the airplane’s weight, takeoff configuration, and runway length.

The end of the runway is the point where the runway surface ends. The end of the stop-way is the point where the stop-way surface ends. The point where the aircraft attains a height of 10.7 m is not a relevant factor in determining the lift-off distance.
