Salt Lake City ARTCC (1962-Present) - One of 20 FAA Air Route Traffic Control Centers in the lower 48 United States. Established in 1962 near Salt Lake City International Airport in Salt Lake City, Salt Lake County, Utah. Assigned an FAA ID of ZLC. Active FAA Air Traffic Control Center. Also known as Salt Lake Center.

Salt Lake City ARTCC.


The Salt Lake Center is located at 2150 W 700 N, Salt Lake City adjacent to the Salt Lake City International Airport. The present facility was Commissioned in 1962. The Salt Lake City Center (ZLC) covers part of the Western Service Area.

Initially, the 20 ARTCCs in the lower 48 States were equipped with IBM 9020 computers to automate some of the ARTCC functions. In 1988 the IBM 3083 computer system known as "Host" replaced the old IBM 9020s in these ARTCCs. On 14 Jun 2012, the FAA decommissioned the 4-decades-old En Route Host computer system at the Seattle and Salt Lake City ARTCCs and replaced the system with the new En Route Automation Modernization (ERAM) system. As of 27 Mar 2015, all 20 of the lower 48 United States ARTCCs had converted to the ERAM system as had the FAA Academy in Oklahoma City, Oklahoma.

ERAM technology is the heart of the Next Generation Air Transportation System (NextGen) and the pulse of the National Airspace System (NAS), helping to advance the transition from a ground-based system of air traffic control to a satellite-based system of traffic management. ERAM can process data from 64 radars versus the 24 radar processing with the legacy HOST system.


The Federal Aviation Administration (FAA) system of 24 FAA Area Control Centers, 20 in the lower 48 United States, one in Alaska, one in Hawaii, one in Puerto Rica and one in Guam. The system operates with radar data provided by FAA radar sites, DoD radar sites, and other federal agency radar sites. These centers provide en route and oceanic services to private, commercial, and military aircraft overflying their respective control areas. As aircraft enter or exit from one control area to the next, responsibility for the aircraft is transferred to the gaining ARTCC. Voice communication between aircraft and the ARTCCs is supported by a network of ground-air radio sites often co-located with the radar sites.

The gathering of radar, beacon and other sensor data are now largely automated and continuous, but the actions necessary to control the airspace are conversational and require some 14,000 FAA air traffic controllers talking directly to pilots in the air and on the ground at terminals. This number does not include military air traffic controllers.
