OPSNET: Facility Type

Before July 1, 2008, OPSNET allowed the input of data by facility types. Today, facilities are sorted by classifications, but facility types are still available in OPSNET for historical purpose.

These are facility types still available in OPSNET:

Types	Name	Description
1	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.
2	Terminal Radar Approach Control (TRACON)	An air traffic control terminal that provides radar-control service to aircraft arriving or departing the primary airport and adjacent airports, and to aircraft transiting the terminal’s airspace.
3	Combination Radar Approach Control and Tower with Radar	An air traffic control terminal that provides radar control services 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.
4	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.
5	Nonapproach Control Tower	An air traffic control tower that is not responsible for using radar to separate traffic. These towers provide air traffic advisories, spacing, sequencing, and separation services to VFR aircraft operating within the vicinity of the airport using direct observation and a radar display as an extension of direct observation.
6	Combined Control Facility	An air traffic control facility that provides approach control services for one or more airports as well as en route air traffic control (center control) for a large area of airspace. Some may provide tower services along with approach control and en route services.
7	Tower with Radar	An airport traffic control terminal that provides traffic advisories, spacing, sequencing and separation services to VFR and IFR aircraft operating within the vicinity of the airport using a combination of radar and direct observations.
9	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.
11	Federal Contract Tower	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.
