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 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 ...

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 approach plate for the ILS or LOC approach to runway 14L at Cologne Bonn Airport, Germany. Approach plates (or, more formally, instrument approach procedure charts) are the printed or digital charts of instrument approach procedures that pilots use to fly instrument approaches during instrument flight rules (IFR) operations.
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. [1] [2]
Point in a direct approach where a 3º normal visual descent can be started to achieve a safe landing and stabilized approach to the RWY - VDP (in distance) = HAT (height over terrain) / 300 (HAT is the height of the MDA read in the approach chart of the AD) VDR VHF digital radio VFO Variable-frequency oscillator: VFR visual flight rules: VG
