In aviation, the instrument landing system (ILS) is a precision radio navigation system that provides short-range guidance to aircraft to allow them to approach a runway at night or in bad weather. In its original form, it allows an aircraft to approach until it is 200 feet (61 m) over the ground, within a 1 ⁄ 2 mile (800 m) of the runway.
Harmonisation between PAPIs and an ILS system must take into account the distance between eye height and ILS receiver height for various aircraft. [1]: 8–33 For a typical 3 degree approach slope, PAPI lights should be angled as follows: 3°30', 3°10', 2°50', 2°30' (3.50°, 3.17°, 2.83°, 2.50°). [1]: 8–36
It is typically located about 1 NM (1.85 km) inside the point where the glideslope intercepts the intermediate altitude and transmits a 400 Hz tone signal on a low-powered (3 watts), 75 MHz carrier signal. Its antenna is highly directional, and is pointed straight up. The valid signal area is a 2,400 ft (730 m) × 4,200 ft (1,280 m) ellipse (as ...
The S-Series of ILS specifications is a common denominator for a set of specifications associated to different integrated logistics support aspects. [1] Originally developed by AECMA (French acronym for the Association Européenne des Constructeurs de Matériel Aeronautique, later ASD), the S-Series suite of ILS specifications is managed currently jointly by multinational teams from the ...

The blind approach navigation system was developed starting in 1932 by Dr. Ernst Kramar of the Lorenz company. [1] [4] It was adopted by Deutsche Lufthansa in 1934 and sold around the world.
