Oakland ARTCC.


The Oakland ARTCC (ZOA) was first Commissioned on 15 May 1937 and is currently located at 5125 Central Ave. in Fremont, California The present location was commissioned on 9 Oct 1960. The Oakland Center covers a part of the FAA's Western service area including vast areas of Pacific Ocean airspace.

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 Oakland Center manages the largest airspace in the world, 9.7% of the world’s surface. This airspace has 140,000 square miles domestically, and 18.7 billion square miles over the Pacific Ocean.

The Oakland Center domestic controllers interface and dialog with many domestic centers, approach controls, and towers on a routine basis in three areas, Area North, Area East, and Area south.

The Oakland Center oceanic controllers interface with 21 different foreign and domestic facilities. Oceanic controllers provide air traffic control service to aircraft principally during the en route phase of flight. Space is divided into Area Pacific North, Area Pacific South. The Pacific South Area contains four non-radar sectors extending over the ocean from the west coast to the Philippines. Traffic consists of daily north/south flows of flights between Australia/New Zealand and Japan/Korea and flights in and out of the Guam area airports, and the Eastern portion between Hawaii and Japan. Additional traffic along the southern portion of the Central East and Pacific (CEP) route system between the Hawaiian Islands and Southern California.
