a. Rejected takeoff

Bottom line

Delaying the primary deceleration force during a rejected takeoff, when every second counts, increases stopping distance. Excessive braking during a rejected takeoff may result in loss of directional control, airplane damage, and/or personal injury. Prior to takeoff, the pilot should identify a point along the runway at which the airplane should be airborne; if that point is reached and the airplane is not airborne, immediate action should be taken to discontinue the takeoff.
