Backtaxi (also known as backtrack) is an airport ground procedure which involves the use of any portion of a runway as a taxiway for an aircraft to taxi in the opposite direction from which it will take off or has landed. [1] [2] The procedure is commonly used at smaller airports and private strips which may not have separate paved taxiways parallel to the runway. It is a higher-risk procedure, as pilots may not see, or hear the radio transmissions from, aircraft taxiing on the runway. [3]
At controlled airports, take-off or landing clearances do not authorize the pilot to reverse course and backtrack along the runway, unless specified by air traffic control. [4] [5] At uncontrolled airports, pilots are recommended to broadcast their intentions while backtracking in the interest of safety; for example, the statement "Entering and backtracking runway 36" would indicate the aircraft is taxiing along a magnetic heading of 180 degrees, against the flow of traffic.
An infamous and rare example of where backtracking was used for large commercial aircraft was the Tenerife airport disaster, where two Boeing 747s at Tenerife North Airport were required to backtaxi in order to position themselves for take-off. [6] The ramps and taxiways were occupied by numerous parked aircraft which had been detoured as a result of a bomb threat at another airport. [7]
An airport is an aerodrome with extended facilities, mostly for commercial air transport. Airports usually consist of a landing area, which comprises an aerially accessible open space including at least one operationally active surface such as a runway for a plane to take off and to land or a helipad, and often includes adjacent utility buildings such as control towers, hangars and terminals, to maintain and monitor aircraft. Larger airports may have airport aprons, taxiway bridges, air traffic control centres, passenger facilities such as restaurants and lounges, and emergency services. In some countries, the US in particular, airports also typically have one or more fixed-base operators, serving general aviation.
The Tenerife airport disaster occurred on March 27, 1977, when two Boeing 747 passenger jets collided on the runway at Los Rodeos Airport on the Spanish island of Tenerife. The collision occurred when KLM Flight 4805 initiated its takeoff run while Pan Am Flight 1736 was still on the runway. The impact and resulting fire killed everyone on board KLM 4805 and most of the occupants of Pan Am 1736, with only 61 survivors in the front section of the aircraft. With 583 fatalities, the disaster is the deadliest accident in aviation history.
According to the International Civil Aviation Organization (ICAO), a runway is a "defined rectangular area on a land aerodrome prepared for the landing and takeoff of aircraft". Runways may be a man-made surface or a natural surface. Runways, taxiways and ramps, are sometimes referred to as "tarmac", though very few runways are built using tarmac. Takeoff and landing areas defined on the surface of water for seaplanes are generally referred to as waterways. Runway lengths are now commonly given in meters worldwide, except in North America where feet are commonly used.
On the evening of February 1, 1991, USAir Flight 1493, a Boeing 737-300, collided with SkyWest Airlines Flight 5569, a Fairchild Swearingen Metroliner turboprop aircraft, upon landing at Los Angeles International Airport (LAX). Though air traffic was not heavy at LAX, as Flight 1493 was on final approach, the local controller was distracted by a series of abnormalities, including a misplaced flight progress strip and an aircraft that had inadvertently switched off the tower frequency. The SkyWest flight was told to taxi into takeoff position, while the USAir flight was landing on the same runway.

Addison Airport is a public airport in Addison, in Dallas County, Texas, United States, 9 mi north of downtown Dallas. It opened in 1954 and was purchased by the town of Addison in 1976. It is home to the Cavanaugh Flight Museum.
Runway Status Lights (RWSL) are a visual alerting system installed in some airport taxiways and runways for the purpose of collision-avoidance. When illuminated, red high-intensity LEDs indicate the presence of another vehicle either departing, occupying, or landing on an active runway. RWSL systems are fully-automated and intended to alert aircrews and ground vehicle operators of a potential runway incursion hazard. They operate as an additional layer of safety, independent of human-issued air traffic control clearances.

A runway incursion is an aviation incident involving improper positioning of vehicles or people on any airport runway or its protected area. When an incursion involves an active runway being used by arriving or departing aircraft, the potential for a collision hazard or Instrument Landing System (ILS) interference can exist. At present, various runway safety technologies and processes are commonly employed to reduce the risk and potential consequences of such an event.

There were no reported injuries or damage, but the narrowly averted disaster was investigated by the National Transportation Safety Board, and caused the Federal Aviation Administration to reevaluate and modify air and ground safety procedures at and around Newark Airport.
On December 20, 1972, North Central Airlines Flight 575 and Delta Air Lines Flight 954 collided on a runway at O'Hare International Airport in Chicago, Illinois, in the United States. Ten people died – all on the North Central aircraft – and 17 were injured in the accident. This was the second major airliner accident to happen in Chicago in December 1972; the other was United Airlines Flight 553, which crashed twelve days earlier on approach to Midway Airport.
On July 7, 2017, an Airbus A320-211 operating as Air Canada Flight 759 was nearly involved in an accident at San Francisco International Airport in San Mateo County, California, United States. The flight, which originated at Toronto Pearson International Airport, had been cleared by air traffic control to land on runway 28R and was on final approach to land on that runway; however, instead of lining up with the runway, the aircraft had lined up with the parallel taxiway, on which four fully loaded and fueled passenger airplanes were stopped awaiting takeoff clearance. The flight crew initiated a go-around prior to landing, after which it landed without further incident. The aircraft on the taxiway departed for their intended destinations without further incident. The subsequent investigation by the National Transportation Safety Board (NTSB) determined that the Air Canada airplane descended to 59 feet (18 m) above the ground before it began its climb, and that it missed colliding with one of the aircraft on the taxiway by 14 feet (4.3 m).
