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.
The Runway Awareness and Advisory System (RAAS) is an electronic detection system that notifies aircraft flight crews on the ground of their position relative to their allocated runway. It is a type of Runway Situation Awareness Tool (RSAT).
Runway incursion involves an aircraft, and a second aircraft, vehicle, or person. It is defined by ICAO and the U.S. FAA as "Any occurrence at an aerodrome involving the incorrect presence of an aircraft, vehicle or person on the protected area of a surface designated for the landing and take off of aircraft."
With seven runway incursions of United States commercial aircraft during January and February, the first two months of 2023 saw the highest rate of such incidents in five years. 2018 to 2022 combined had 23 comparable incidents, 5 of which occurred in 2022. [1]
The Airport Movement Area Safety System (AMASS) visually and aurally prompts tower controllers to respond to situations which potentially compromise safety. AMASS is an add-on enhancement to the host Airport Surface Detection Equipment Model 3 (ASDE-3) radar that provides automated aural alerts to potential runway incursions and other hazards.
When an airport is being analyzed for designing an instrument approach procedure, an obstacle departure procedure assessment is conducted first.Pass the departure end of the runway, Surveyors establish an obstacle clearance surface (OCS), which is an imaginary surface that rises at a 40:1 ratio under standard conditions, or 152ft per nautical miles.
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. [10] [11] 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 ...
