Display Systems
ASR data is displayed on Automated Radar Terminal System (ARTS), Common Automated Radar Terminal System (CARTS), and Standard Terminal Automation Replacement System (STARS) display consoles in control towers and Terminal Radar Approach Control (TRACON) rooms, usually located at airports. CARTS will be replaced with STARS at all TRACONs during TAMR Phase 3 - Segment 1 as announced by the FAA Federal Aviation Administration in the Spring of 2011. The fate of the remaining ARTS systems will be determined through the FAA's upcoming announcement of TAMR Phase 3 - Segment 2.
The Standard Terminal Automation Replacement System (STARS) is a joint Federal Aviation Administration (FAA) and Department of Defense (DoD) program to replace Automated Radar Terminal Systems (ARTS) and other capacity-constrained, older technology systems at 172 FAA and up to 199 DoD terminal radar approach control facilities and associated towers.
STARS will be used by controllers, at facilities who already have it installed, to provide air traffic control (ATC) services to aircraft in terminal areas. Typical terminal area ATC services are defined as the area around airports where departing and arriving traffic are served. Functions include aircraft separation, weather advisories, and lower level control of air traffic. The system is designed to accommodate air traffic growth and the introduction of new automation functions which will improve the safety and efficiency of the US National Airspace System (NAS) as the legacy systems are replaced.
Airport Surveillance Radar is beginning to be supplemented by ADS-B Automatic dependent surveillance-broadcast in the US and other parts of the world. As of Spring 2011, ADS-B is currently operational and in use at the Philadelphia, PA TRACON and Louisville, KY TRACON. ADS-B is a GPS based technology that allows aircraft to transmit their GPS determined position to display systems as often as once per second, as opposed to once every 4 seconds for a short range radar, or once every 13 seconds for a slower rotating long range radar. The FAA is mandating that ADS-B be fully operational and available to the NAS by the year 2020. This will allow for older radars to possibly be decommissioned in order to increase safety and also cut costs. As of 2011, there is no definitive list of radars that will be decommissioned as a result of ADS-B.

Famous quotes containing the words display and/or systems:
“Lovers of painting and lovers of music are people who openly display their preference like a delectable ailment that isolates them and makes them proud.”
—Maurice Blanchot (b. 1907)
“People stress the violence. That’s the smallest part of it. Football is brutal only from a distance. In the middle of it there’s a calm, a tranquility. The players accept pain. There’s a sense of order even at the end of a running play with bodies stewn everywhere. When the systems interlock, there’s a satisfaction to the game that can’t be duplicated. There’s a harmony.”
—Don Delillo (b. 1926)
