Draw you flight path on a map and calculate the great circle distance in nautical miles and kilometers. Get estimated flight time by choosing an aircraft type or entering the cruising speed.Click in the large textfield above to enter all the airports of your flight route!
Great Circle Map displays the shortest route between airports and calculates the distance. It draws geodesic flight paths on top of Google maps, so you can create your own route map.
Calculate online the great circle, the shortest distance between two locations on Earth.
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.
Distance Units: Earth model: Javascript Great Circle Calculator using ellipsoidal earth models.
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.
