Seattle ARTCC Complex in Auburn, Washington.


The Seattle ARTCC is located at 3101 Auburn Way South, Auburn Washington. and was opened at this location in 1962.

The original Seattle ARTCC was located at the Boeing Field Administration Building in 1940 and control instructions were relayed to pilots via company phone lines. In 1950, Seattle ARTCC moved to the Seattle Tacoma Airport (SeaTac) Administration Building, where the first radio was commissioned in the facility allowing direct controller to pilot. In 1962 the ARTCC moved from SeaTac to its current location in Auburn, Washington.

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.

The Seattle ARTCC airspace encompasses some 261,000 square miles including all of Washington, most of Oregon, and portions of Montana, Idaho, Nevada, and California. The center boundaries extend from the Canadian border to Northern California and from western Montana to 150 miles off the Pacific Coast. There are nine approach controls in Seattle Center’s airspace.

The Seattle Center also works with Vancouver and Edmonton Control Centers to the north, Salt Lake City center to the east, and Oakland Center to the south and west.
