Southern California TRACON
The Southern California Terminal Radar Approach Control (SoCal TRACON or SCT) (radio callsign: SoCal Approach/Departure) is located in San Diego, California. SCT is a part of the Air Traffic Organization of the US Federal Aviation Administration. SCT sequences and separates air traffic in the Southern California region. It is the busiest air traffic control facility in the world. SCT serves the following major Southern California airports (in order of volume, Class B & C), in addition to many surrounding satellite airports. SCT is broken down into six areas and a Traffic Management Unit: Each area has five  or six individual sectors that are worked by controllers. SoCal TRACON is responsible for the handling of aircraft departing and arriving these airports, generally below . SCT is responsible for sequencing inbound, separating from crossing and VFR traffic, and departing traffic. Separation is achieved by vectoring traffic and assigning altitudes.
