measured landing distance

The distance established from a point where the aircraft is 50 ft (15 m) over the runway (assumed to be a hard, level, dry surface) at a speed not less than “1.3 V-stall” (1.3 × stalling speed) to the point where the airplane reaches the full stop, following a steady, full-flap, no-power approach, and maximum braking.
