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.^[3]

Preventing runway excursions can necessitate building new airports, when there is not room to expand existing runways. In July 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.^[4]

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. EMAS was installed at LaGuardia Airport starting in 2005 and ending in 2015.^[4] In October 2016, a Boeing 737 aircraft with 37 persons 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.^[5][6][7]

As of December 2020^[update], 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.^[8]

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.^[4]

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.
