# 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 successfully reject the 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. Runway excursions may occur both during takeoff or landing.
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.

## Management and prevention

Efforts to address runway excursion either focus on preventing runway excursions, or on minimizing the amount of damage or injury caused by a runway excursion. In the latter category, aviation safety regulators may establish standards such as minimum runway safety areas intended to allow adequate time and distance for an aircraft to stop in the event of a runway excursion.

### Runway widening and extension

A key aspect of preventing runway excursions is providing runways of sufficient length and width to accommodate the aircraft used at an airport. In the 1960s, the advent of jet airliners such as the Boeing 707, which operate at faster speeds including at takeoff and landing relative to earlier propeller-driven airliners, required longer runways. In the mid-1960s, the Federal Aviation Administration (FAA) proposed increasing minimum runway length requirements by 800 feet (240 m) at all U.S. airports with jet airliner service, extending to 1,200 feet (370 m) feet in rain or snow conditions. However, these requirements would have necessitated building extending runways or even building new airports in some cities. After strong industry response, the FAA withdrew the proposal and instead only mandated a fifteen per cent increase to minimum runway length during wet or slippery landing conditions.
Preventing runway excursions can necessitate building new airports, when there is not room to expand existing runways. On July 1, 1965, Continental Airlines Flight 12 (a Boeing 707) overran the runway while landing in rain and high winds at Kansas City Municipal Airport. Investigators ruled out pilot error, and determined it would have been impossible to stop the aircraft in the available runway length. Extending the 7,000-foot (2,100 m) runway was not possible due to space limitations surrounding the urban airport, and construction on Kansas City International Airport north of the city was approved the next year, opening in 1972 with runways 9,500 feet (2,900 m) and 9,000 feet (2,700 m) in length.

### Engineered materials arrestor system

Airports such as LaGuardia Airport in Queens, New York, may lack adequate space to meet runway safety area standards. As a result, in the 1990s, the FAA began conducting research on new technology to rapidly stop aircraft in less than 1,000 feet (300 m) in the event of a runway overrun.
The engineered materials arrestor system (EMAS) was developed as a high energy absorbing material that could be installed as a surface beyond the end of runways, which was designed to collapse under the weight of an aircraft (absorbing energy and slowing the plane in the process) in the event of an overrun. Installation of EMAS at LaGuardia Airport started in 2005 and finished in 2015. In October 2016, a Boeing 737 aircraft with 37 people aboard, including Republican vice-presidential candidate Mike Pence, overran the runway while landing at LaGuardia. EMAS was credited with bringing the plane to a stop safely and with no serious damage or casualties.
As of December 2020, EMAS has been installed at more than 100 runway end locations at more than 50 commercial airports in the United States, and has safely stopped 15 aircraft involved in runway overruns.

### Flight systems technology

Airbus is developing the Runway Overrun Prevention System, a flight systems technology intended to prevent runway overruns by increasing pilots' situational awareness and enhancing automation during landings.

### Runway condition assessment

Takeoff and Landing Performance Assessment (TALPA) was introduced in 2016, whereby airport operators report Runway Condition Codes (RWYCC) for take-off and landing.

## Notable runway excursions

The following list includes runway excursions, which are notable because they resulted in fatalities, aircraft destruction, or substantial aviation safety changes or improvements.
| Event | Year | Location | Description |
| British European Airways Flight 609 | 1958 | Munich-Riem Airport, Munich, West Germany | The Airspeed Ambassador crashed on its third attempt to take off at Munich-Riem Airport due to runway slush. The flight was carrying the Manchester United football team back home, along with supporters and journalists, from a European Cup match in Belgrade, Yugoslavia (now Serbia). There were 44 people on board, 20 of whom died at the scene. Three more injured died at hospital, resulting in 23 fatalities with 21 survivors. |
| TAP Air Portugal Flight 425 | 1977 | Cristiano Ronaldo International Airport, Portugal | A Boeing 727 operating the service overran the airport's runway before crashing onto the nearby beach and exploding, killing 131 of the 164 people on board. It remains TAP's only fatal accident in its history. The runway was 5,200 ft (1,600 m) long at the time of the crash. It would be extended in 1986 to 5,900 ft (1,800 m) and again in 2000 to 9,124 ft (2,781 m). |
| Aeroservicios Ecuatorianos Flight 767-103 | 1984 | Mariscal Sucre International Airport, Quito, Ecuador | The DC-8 cargo flight to Guayaquil failed to take off at Quito Airport, hitting an instrument landing system (ILS) antenna at the end of the runway and then striking several houses. All 4 crew and 49 people on the ground were killed. |
| American Airlines Flight 70 | 1988 | Dallas Fort Worth International Airport, Dallas–Fort Worth metroplex, United States | A McDonnell Douglas DC-10-30 overran a runway at Dallas/Fort Worth International Airport (DFW) after warning signals prompted the flight crew to initiate a rejected takeoff. The jetliner continued to accelerate for several seconds and did not stop until it had run 1,100 feet (335 m) past the runway threshold, collapsing the nose landing gear. Two crew were seriously injured and the remaining 12 crew and 240 passengers escaped safely; the aircraft was severely damaged and was written off. Investigators attributed the overrun to a shortcoming in the design standards when the DC-10 was built; there had been no requirement to test whether worn (as opposed to new) brake pads were capable of stopping the aircraft during a rejected takeoff, and eight of the ten worn pad sets had failed. |
| American Airlines Flight 102 | 1993 | Dallas Fort Worth International Airport, Dallas–Fort Worth metroplex, United States | Landing in stormy conditions with a crosswind, a McDonnell Douglas DC-10 began to weathervane, and the captain failed to use sufficient rudder control to regain the proper ground track. The plane departed the right side of the runway. All 202 occupants on board survived, with 2 passengers suffering serious injuries during the emergency evacuation. The aircraft was badly damaged and was written off. |
| China Airlines Flight 605 | 1993 | Kai Tak Airport, Hong Kong | To avoid a runway overrun and collision with the approach light system, the captain of a Boeing 747-400 deliberately veered the plane off the left side of the runway and into Victoria Harbour. No one was killed, but the plane was written off. |
| Philippine Airlines Flight 137 | 1998 | Bacolod City Domestic Airport, Bacolod, Philippines | The Airbus A320-214 overran the runway due to pilot error and crashed into a residential area.
