Closest airport with whatever you need.

Pick an origin. Pick the runway, surface, lighting, approach, or feature that matters. Get the nearest matches across 72,000 airports — sorted by great-circle distance, ranked. Browser-side; the full dataset never leaves your machine.

Method.

Distance

Great-circle (Haversine) on a spherical earth at R = 6371 km. Good to ~0.3% on continental legs — accurate enough for diversion ranking.

Bearing

Initial bearing from origin to target, true north = 0°, clockwise. Magnetic variation is not applied — use it as a relative direction, not for navigation.

Filters

Same compact bitfield encoding as the Airport Map. Type / surface / features come from FAA NASR via OurAirports; approach types from the FAA dTPP metafile (current cycle).

Privacy

The whole computation runs in your browser. Your origin coordinates never reach our servers. The dataset (~5.5 MB) is fetched once and cached.

Caveat: this is a finder, not a flight planner. It doesn't know wind, terrain, fuel, ceiling, NOTAM closure, or whether the field is staffed today. Treat it as a ranked candidate list — verify each option through the per-airport page (/atlas/airports/) and a current briefing before committing.
