Coverage is organized in three levels:
  • Facility: an airport, a TRACON, or an en-route center. Identified by facility_id.
  • Channel category: a group of channels within a facility, such as Ground, Approach, or Low.
  • Channel: one radio frequency. Identified by atc_channel_id.
A channel can belong to more than one facility, for example a center sector that also serves an airport. It can also belong to more than one category of a facility, for example a channel used for both Approach and Departure. That is why transcripts and events carry a list of facility_ids. Use GET /api/v0/facilities to list the facilities we cover with their categories and channels, and GET /api/v0/facilities/search to find any facility by code or name.

​
Available channels

Data is returned only for channels marked is_available in GET /api/v0/facilities. Channels with is_available set to false are listed so you can see our coverage, but no data is returned for them.
ATIS channels are listed with is_available set to false. ATIS broadcasts are not available through the API.
To ask for a channel to be turned on, email support@enhancedradar.com with its atc_channel_id.

​
Airlines

GET /api/v0/airlines lists the airlines you can filter by with airline_id. A flight belongs to an airline when its callsign starts with the airline’s three-letter ICAO designator.
