A
Terminal Control Center (also known as
Terminal Radar Approach Control or
TRACON in the United States) is an
Air traffic control Center usually located within the vicinity of a large airport. Typically, the Terminal Control Center controls aircraft within a 30-50 nautical mile (56 to 93 km) radius of the airport between the surface and 10,000 feet. A Terminal Control Center is sometimes also known as an
Approach Control or
Departure Control. In Canada, Approach Control may be called
Arrival or
Terminal. In military aviation, it is often known as
RAPCON (Radar Approach Control).
Terminal Control Center radar facilities
Terminal Control Centers normally have their own radar system that allow
air traffic controllers to track aircraft. This is typically based on one or more Airport Surveillance Radar(s) (ASR), sweeping once every 6 seconds. The largest TRACON in the world (Southern California Consolidated TRACON - SCT, Callsign
SoCal Approach) services 62 airports and is located in San Diego, California. This huge facility utilizes 10 radar sites and is soon to expand to 11. Most US terminal Radar Approach Control (TRACON) facilities utilize an ASR-9 with a range on 63 7/8 miles and a scan rate (rotation) of approximately 4.25 seconds.
These frequent updates help controllers see the result of direction changes quickly. Larger U.S. TRACONs are able to directly incorportate enroute long range Air Route Surveillance Radar(s) (ARSR) into their automated tracking systems as a backup. Smaller U.S. TRACONs also have the capability to make use of CENRAP (CENter RAdar Presentation) as a backup if their primary system fails. This makes use of en-route surveillance radar used by Air Route Traffic Control Centers (ARTCCs). Expanded separation minimums (5 nautical miles versus 3 nautical miles) are required when in this mode.
Terminal Control Center Control positions
Terminal Control Center control positions usually include a radar controller and a coordinator who generally stands behind the radar position.
Radar controller
The radar controller is responsible for ensuring appropriate separation, and issuing traffic and other local aviation information for aircraft under its control. Additionally, the radar controller is responsible for ensuring all required coordination with other controllers in the tower, Terminal Control Center, or en-route center is completed, making computer required computer entries, and updating the
flight progress strips.
Coordinator
The coordinator provides coordination support for the radar controller. He/she will provide inter/intra facility coordination when required for the radar controller and make computer entries.
"Data", "Handoff", or "Support" controller
Some Terminal Control Centers have the ability to staff a second position at the radar console, referred to as a "Data", "Handoff", or "Support" controller. This position is responsible for providing direct support by coordinating for the radar controller, managing flight progress strips, and making computer entries. When this position is staffed, the coordinator duties are greatly reduced, allowing him/her to provide support for a number of positions. The support controller may make transmissions on the radio along with the main controller: the support controller focuses on the more procedural aspects of controlling (e.g. holding aircraft) while the main controller focuses on accurately radar-vectoring the approach sequence.
Terminal Control Center traffic responsibilities
Terminal Control Centers are responsible for providing all ATC services within their airspace. Generally, there are four types of traffic flows controlled by Terminal Control Center controllers. These are departures, arrivals, overflights, and aircraft operating under Visual Flight Rules (VFR).
Departure aircraft
Departure aircraft are received from the tower and are generally 1,000 feet to 2,000 feet high, climbing to a pre-determined altitude. The Terminal Control Center controller working this traffic is responsible for clearing all other Terminal Control Center traffic and, based on the route of flight, placing the departing aircraft on a track and in a geographical location (sometimes referred to as a "gate" or "exit") that is pre-determined through agreements for the Area Control Center controller. This positioning is designed to allow the en-route center to integrate the aircraft into its traffic flow easily.
Arrival aircraft
Arrival aircraft are received from the Area Control Center in compliance with pre-determined agreements on routing, altitude, speed, spacing, etc. The Terminal Control Center controller working this traffic will take control of the aircraft and blend it with other aircraft entering the center airspace from other areas or "gates" into a single, parallel or perpendicular final for the runway. The spacing is critical to ensure the aircraft can land and clear the runway prior to the next aircraft touching down on the runway. The tower may also request expanded spacing between aircraft to allow aircraft to depart or to cross the runway in use.
Overflight aircraft
Overflight aircraft are aircraft that enter the Terminal Control Center airspace at one point and exit the airspace at another without landing at an airport. They must be controlled in a manner that ensures they remain separated from the climbing and descending traffic that is moving in and out of the airport. Their route may be altered to ensure this is possible. When they are returned to the en-route center, they must be on the original routing unless a change has been coordinated.
VFR aircraft
If the class of airspace allows flight under Visual Flight Rules, such aircraft are handled as traffic permits. Controllers will provide traffic information to ensure safety with other aircraft, and may even positively separate VFR aircraft from other aircraft, depending on the class of airspace. Controllers lack the level of control over these aircraft that they have over aircraft on operating under Instrument Flight Rules as they will not want to vector VFR aircraft into
Instrument meteorological conditions. Controllers usually provide information for the pilot about traffic in the immediate vicinity and weather reports if applicable. This ensures separation from Instrument Flight Plan (IFR) aircraft is maintained in the critical flight areas around the airports.
Terminal Control Center availability
Not all airports have a Terminal Control Center available. In this case, the en-route center will coordinate directly with the tower and provide this type of service where radar coverage permits. Generally, however, the separation minimums are greatly increased. In many countries, mid-sized airports without a Terminal Control Center have a dedicated Approach Radar Controller based upon the airport itself to sequence inbounds and to provide radar services to aircraft in the vicinity of the airport.
