AIRPORT SURVEILLANCE RADAR

The direction and coordination of aircraft within specific terminal areas is carried out by airport surveillance radar (ASR) facilities. Approach and departure controls manage traffic at airports with ASR. This radar system is designed to provide relatively short-range coverage in the airport vicinity and to serve as an expeditious means of handling terminal area traffic. The ASR also can be used as an instrument approach aid. Terminal radar approach control facilities (TRACONs) provide radar and nonradar services at major airports. The primary responsibility of each TRACON is to ensure safe aircraft transitioning from departure to cruise flight or from cruise to a landingapproach.

Usually the busiest terminals in the country have the most sophisticated computers and programs. The type of system installed is designated by a suffix of numbers and letters. For example, an ARTS-IIIA installation can detect, track, and predict primary, as well as secondary, radarreturns.

On a controller’s radar screen, ARTS equipment automatically provides a continuous display of an aircraft’s position, altitude, groundspeed, and other necessary information. This information is updated continuously as the aircraft progresses through the terminal area. To gain maximum benefit from the system, each aircraft in the area must be equipped with a Mode C altitude encoding transponder, although this is not an operational requirement. Direct altitude readouts eliminate the need for time consuming verbal communication between controllers and pilots to verify altitude. This helps to increase the number of aircraft that may be handled by one controller at a giventime.
