Airport Frequencies API

healthy 4,578 Subscribers

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.

Runways API

Every runway in the world as an API — 47,000+ runways at 40,000+ airports, from the OurAirports dataset. List all the runways at any airport by ICAO/local ident (e.g. KJFK → four runways, the longest 13R/31L at 14,511 ft), with each runway's length (feet and metres), width, surface (asphalt, concrete, grass, …), lighting and both-end designators, true headings and coordinates. Or filter runways fleet-wide by surface, minimum length and lighting. Ideal for flight planning, flight simulators, EFB and aeronautical apps, and aviation analytics.

Navaids API

Radio navigation aids (navaids) as an API — 11,000+ VOR, NDB, DME, TACAN, VORTAC and VOR-DME beacons across 231 countries, from the OurAirports dataset. Look up a navaid by its ident (e.g. JFK → Kennedy VOR-DME 115.9 MHz), search by name/ident with country and type filters, or find all navaids within a radius of any coordinate. Each record carries the ident, name, type, frequency (kHz and MHz), elevation, country and any associated airport. Ideal for aviation tools, flight simulators, EFB apps, flight planning and aeronautical charts.

METAR / TAF Aviation Weather API

Live aviation weather for any airport as an API, relayed from NOAA's Aviation Weather Center. Get the current METAR observation for an ICAO station (e.g. KJFK → New York JFK: temperature, dewpoint, wind, visibility, altimeter, cloud layers, flight category VFR/MVFR/IFR/LIFR and the raw report) or the TAF terminal aerodrome forecast. Query one station or up to 10 at once (KJFK,EGLL,EDDF). Both decoded fields and the raw text are returned. Ideal for flight-planning tools, aviation dashboards, drone/UAV operations and weather apps.

Aircraft Types API

Resolve and search aircraft type designators — turn the IATA (e.g. 738) and ICAO (e.g. B738) aircraft codes returned by flight-data APIs into readable model names like "Boeing 737-800". Look up by IATA code, ICAO code or name, search 240+ aircraft types, or fetch the whole list. Bundled, fast and always available — a handy companion to flight, airline and airport data.
