Traffic pattern indicators are arranged in pairs in conjunction with landing strip indicators and used to indicate the direction of turns when there is a variation from the normal left traffic pattern. If there is no segmented circle installed at the airport, traffic pattern indicators may be installed on or near the end of the runway. [11]
Vectoring is the provision of navigational guidance to aircraft in the form of specific headings, based on the use of an ATS surveillance system. Aircraft may be vectored to: apply ATS surveillance system separation; achieve an expeditious flow of aircraft; maximise use of available airspace; comply with noise abatement procedures
In aviation, a traffic pattern indicator is an L-shaped device which show the airfield traffic pattern to the in-flight aircraft over an aerodrome. [2] The short arm of the "L" represents the base leg, and the long arm the final approach. [3] If no segmented circle is installed, traffic pattern indicators may be installed on or near runway ends ...
It is the main air traffic control system for the airspace around airports. At large airports it typically controls traffic within a radius of 60 miles (96 km) of the airport below an elevation of 25,000 feet. The sophisticated systems at large airports consist of two different radar systems, the primary and secondary surveillance radar. [1]

The overall concept is known as ground-controlled approach (GCA), and this name was also used to refer to the radar systems in the early days of its development. An Air Force air traffic controller is reflected in the precision approach radar scope (1980) PAR radars use a unique type of radar display with two separate "traces", separated ...
