About AvMap
Updated
AvMap is a free web app for drawing flight routes, great-circle distances, and aircraft range rings on a flat map or a 3D globe.
What it does
Type airport codes such as JFK-LHR and AvMap draws the
shortest path between the airports and shows the distance. You can
chain stops, map whole networks, add range rings, style routes, and
open any airport for local time, daylight, weather, runways, and radio
frequencies. Maps can be shared as a link, exported as an image, or
embedded on another site. There is no account to create.
Where the data comes from
- Airports, runways, and frequencies: OurAirports, an open dataset. AvMap refreshes it automatically each week and currently lists 41,306 airports and airfields.
- Base map: tiles from OpenFreeMap using OpenStreetMap data.
- Weather: current observations from the NOAA Aviation Weather Center where available, otherwise from Open-Meteo.
- Airport alerts: delays and closures from the FAA’s public airport status feed and airport-specific air traffic regulations from the EUROCONTROL live dashboard. European airspace restrictions are excluded; coverage may be incomplete.
How distances are calculated
AvMap uses the haversine formula on a sphere with a mean radius of 6,371.0088 km. The result is the great-circle distance, which is shorter than the distance most flights actually fly. Read how great-circle routes work.
What AvMap is not
AvMap is for visualization, research, and discussion. Do not use it for navigation, dispatch, weather decisions, or flight planning. Data can be delayed or incomplete, so check official sources before relying on it. See the terms for details.
