Airport Frequencies API
Airport radio communication frequencies as an API — 30,000+ frequencies at 11,000+ airports, from the OurAirports dataset. List every published frequency at an airport by ident (e.g. KJFK → Approach 125.7/127.4/132.4, ATIS, Tower, Ground, Clearance, …), or filter fleet-wide by type or exact frequency (e.g. find every airport using the emergency frequency 121.5). Each record carries the airport, frequency type (TWR, GND, ATIS, APP, CTAF, UNICOM, CNTR, …) with a readable name, the description and the frequency in MHz. Ideal for aviation radio, flight simulators, EFB, scanner and flight-planning apps.
