Beyond flight status
Where SkyLink API goes further
SkyLink combines databases with true real-time ADS-B, weather and ML predictions in a single, consistent schema.
True ADS-B, ~5-second updates
SkyLink reads raw ADS-B receiver data — ICAO24 hex, callsign, latitude, longitude, altitude, ground speed and track — sampled roughly every 5 seconds, with bounding-box queries for any map viewport.
Decoded METAR & TAF weather
Fully decoded METAR observations and TAF forecasts across US and international airfields — wind, QNH, visibility, cloud layers, temperature and dew point — alongside live flight data.
Complete airport & navaid database
Search 74,000+ airports by ICAO, IATA, city, location or IP, with runways, frequencies, navaids (VOR, NDB, ILS) and elevation.
ML flight-time, FAA delays & carbon
An ML gate-to-gate flight-time model, a real-time FAA delay-status feed, and ICAO-based carbon estimates — all behind one key.
