A typical runway safety area, marked in brown color. A runway safety area (RSA) or runway end safety area (RESA, if at the end of the runway) is defined as "the surface surrounding the runway prepared or suitable for reducing the risk of damage to airplanes in the event of an undershoot, [1] overshoot, or excursion from the runway."
The Obstacle Free Zone (OFZ) clearing standard precludes taxiing and parked airplanes and object penetrations, except for frangible navigation aid locations that are fixed by function. It is centered above the runway and the extended runway centerline and is intended to provide clearance protection for aircraft landing or taking off from the ...
The "runway condition" is a runway's current status in relation to current meteorological conditions and air safety. Dry: the surface of the runway is clear of water, snow or ice. Damp: change of color on the surface due to moisture. Wet: the surface of the runway is soaked but there are no significant patches of standing water.
An engineered materials arrestor system, engineered materials arresting system (EMAS), or arrester bed [1] is a bed of engineered materials built at the end of a runway to reduce the severity of the consequences of an aircraft running off the end of a runway. Engineered materials are defined in FAA Advisory Circular No 150/5220-22B as "high ...
A precision approach path indicator (PAPI) is a system of lights on the side of an airport runway threshold that provides visual descent guidance information during final approach. It is generally located on the left-hand side of the runway approximately 300 metres (980 ft) beyond the landing threshold of the runway.
Glideslope critical area – aircraft/vehicles/persons or physical obstructions are not authorized in or over the critical area when an arriving aircraft is between the ILS final approach fix and the airport unless the aircraft has reported the airport in sight and is circling or sidestepping to land on a runway other than the ILS runway.
Runway 13R at Palm Springs International Airport An MD-11 at one end of a runway. In aviation, a runway is an elongated, rectangular surface designed for the landing and takeoff of an aircraft. [1] Runways may be a human-made surface (often asphalt, concrete, or a mixture of both) or a natural surface (grass, dirt, gravel, ice, sand or salt).
Emission patterns of the localizer and glide slope signals Glide slope station for runway 09R at Hannover Airport in Germany. In aviation, instrument landing system glide path, commonly referred to as a glide path (G/P) or glide slope (G/S), is "a system of vertical guidance embodied in the instrument landing system which indicates the vertical deviation of the aircraft from its optimum path ...
