Runway excursion

A runway excursion is a runway safety incident in which an aircraft makes an inappropriate exit from the runway. This happens mainly due to late landings or inappropriate runway choice. There are several types of runway excursions: A departing aircraft fails to become airborne or is unsuccessful in rejecting takeoff before reaching the end of the designated runway. A landing aircraft is unable to stop before the end of the designated runway is reached, causing it to keep moving and leave the runway. An aircraft taking off, rejecting takeoff or landing departs the side of the designated runway, not airborne. When an aircraft exits the end of the runway, this is referred to as runway overrun (or informally, runway overshoot). Runway excursions can happen because of pilot error, poor weather, or a fault with the aircraft. According to the Flight Safety Foundation, as of 2008, runway excursions were the most frequent type of landing accident, slightly ahead of runway incursion. For runway accidents recorded between 1995 and 2007, 96% of runway accidents and 80% of accidents with fatalities involved runway excursions.
