Calculate the great circle distance between two points. Calculate the great circle distance between two addresses. Draw a direct route between two airports, or multiple airport pairs. Draw range rings (concentric circles) around a point. Calculate coordinates at a given bearing and distance.
Does the Great Circle Mapper assume Earth is a sphere? How does the Great Circle Mapper calculate distances and paths? Why does the example in Ed Williams' Aviation Formulary calculate a different distance for LAX-JFK?
Displays a map on which the great circle path for one or more routes is plotted and calculates the distance along each route. Ranges from one or more locations may also be plotted, along with go/no-go areas for ETOPS operations at various rule times.
