airplane reference field length

airplane reference field length

Balanced field length is determined by establishing failure speed so that runway distance from that point to continue takeoff on the remaining engine or to decelerate and stop is the same.

The minimum field length required for takeoff at maximum certified takeoff mass, at sea level, in standard atmospheric conditions, in still air and zero runway slope, as shown in the appropriate airplane flight manual prescribed by the certificating authority or equivalent data from the airplane manufacturer. Field length means balanced field length for airplanes, if applicable, or takeoff distance in other cases.
