Precision approach radar or PAR is a type of radar guidance system designed to provide lateral and vertical guidance to an aircraft pilot for landing, until the landing threshold is reached. [1] Controllers monitoring the PAR displays observe each aircraft 's position and issue instructions to the pilot that keep the aircraft on course and ...
The AN/SPN-35 is a computerized automatic landing system installed on the Tarawa-class amphibious assault ship and other LHA/LHD-class warships to give control for aircraft during the final approach and landing. [3] [4] The Joint precision approach and landing system (JPALS) is slated to replace the AN/SPN-35 on U.S. Navy amphibious assault ...

The AN/SPN-46(V)1 is a Precision Approach and Landing System, manufactured in the United States, by Textron Systems, which is used on aircraft carriers of the United States Navy. The radar uses two dual-band radar antennas, which also function as transmitters, to guide planes or helicopters to the ship.

ILS planes. An instrument landing system operates as a ground-based instrument approach system that provides precision lateral and vertical guidance to an aircraft approaching and landing on a runway, using a combination of radio signals and, in many cases, high-intensity lighting arrays to enable a safe landing during instrument meteorological conditions (IMC), such as low ceilings or reduced ...
An LPV approach is an approach with vertical guidance, APV, to distinguish it from a precision approach, PA, or a non-precision approach, NPA. SBAS criteria includes a vertical alarm limit more than 12 m, but less than 50 m, yet an LPV does not meet the ICAO Annex 10 precision approach standard. [2]
The term GCA may refer to any type of ground radar guided approach such as a PAR, PAR without glideslope or ASR. [1] When both vertical and horizontal guidance from the PAR is given, the approach is termed a precision approach. If no PAR glidepath is given, even if PAR equipment is used for lateral guidance, it is considered a non-precision ...
