OPSNET: Facility Classification

In all OPSNET views, you may select among the following facility classifications:

Name	Description
Tower without Radar	An airport traffic control terminal that provides service using direct observation primarily to aircraft operating under Visual Flight Rules (VFR). These terminals are located at airports where the principal user category is low performance aircraft.
Terminal Radar Approach Control (TRACON)	An FAA air traffic control facility using radar and air/ground communications to provide approach control services to aircraft arriving, departing, or transiting the airspace controlled by the facility.
RAPCON	A terminal air traffic control facility using radar and non-radar capabilities to provide approach control services to aircraft arriving, departing, or transiting airspace controlled by the facility.
CERAP	An FAA air traffic control facility combining the functions of an ARTCC and a TRACON.
Combined TRACON and Tower with Radar	An air traffic control terminal which provides radar control to aircraft arriving or departing the primary airport and adjacent airports, and to aircraft transiting the terminal's airspace. This terminal is divided into two functional areas: radar approach control positions and tower positions. These two areas are located within the same facility, or in close proximity to one another, and controllers rotate between both areas.
Combination Non-Radar Approach Control and Tower without Radar	An air traffic control terminal that provides air traffic control services for the airport at which the tower is located and without the use of radar, approach and departure control services to aircraft operating under Instrument Flight Rules (IFR) to and from one or more adjacent airports.
Towers with Display (VFR)	ATCT providing takeoff and landing services only. It does not provide approach control services.
Combined Control Facility	An air traffic control terminal that provides radar approach control services for two or more large hub airports, as well as other satellite airports, where no single airport accounts for more than 60 percent of the total Combined TRACON facility’s air traffic count. This terminal requires such a large number of radar control positions that it precludes the rotation of controllers through all positions.
Towers with Radar	Single facilities that combine an approach control with an ATCT providing both radar and non-radar air traffic control services.
Air Route Traffic Control Center (ARTCC)	An air traffic control facility that provides air traffic control service to aircraft operating on IFR flight plans within controlled airspace and principally during the en route phase of flight. When equipment capabilities and controller workload permit, certain advisory/assistance services may be provided to VFR aircraft.
Combined TRACON	An air traffic control terminal that provides radar approach control services for two or more large hub airports, as well as other satellite airports, where no single airport accounts for more than 60 percent of the total Combined TRACON facility’s air traffic count. This terminal requires such a large number of radar control positions that it precludes the rotation of controllers through all positions.
Federal Contract Tower	Low-activity VFR ATCT providing air traffic control services for a municipality or subdivision thereof while under contract to the FAA.
Non-FAA Facility	Non-federal low-activity VFR ATCT providing air traffic control services for a municipality or subdivision thereof which is not under contract to the FAA. The municipality has the option of using its own employees or subcontracting for these services.
