Astudy of jet transport accidents occurring in the ground phase of operations has produced interesting findings. The refused takeoff is the most critical maneuver in ground operations. Neither runway slipperiness nor engine failure has proved to be a dominant factor in the precariousness of this operation.Activities are reviewed that can and must take place before a deceleration is attempted in order to enhance the probability of an unexciting stop. The contributions of several supporting institutions in these activities are outlined. Emphasis is placed on pilot anticipation of conditions and preplanning actions.Once all precommitment activities are properly accomplished, the deceleration itself is relatively straightforward. The physical techniques using known airplane dynamics are briefly discussed.
