5 maj 2015 · Flights like this one follow what are know as Great Circle routes—the shortest distance between two points on a sphere. A polar plot of the Chicago-Dubai Great Circle route, courtesy gcmap.com. To see the great circle route between any two airports around the world, gcmap.com is a useful tool.
29 kwi 2014 · The shortest route between any two points on the earth’s surface is called a great circle. Although air routes look curved on flat maps, airliners do try to fly straight lines between cities. Exact routes vary due to winds, flight rules, and political borders (we don’t fly over certain countries).
Choosing the shortest flight route is important to save both time and fuel. Here you can learn all about how great circle navigation helps the aviation industry to optimize its paths and why the shortest routes are usually displayed as an arc in a map.
5 lip 2019 · The takeaway is this: A route that looks longer on the map is because of the distortion created by map projections like the Mercator Projection. In navigation, pilots often use great circles (geodesic) as the shortest distance flight.
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.
The Great Circle Mapper assumes the speed of sound is 574 knots (about 660.5 miles per hour or 1063 kilometers per hour), which is a close approximation for the lower stratospheric altitudes from 36,000 feet to well above 65,000 feet where transport jets usually fly, assuming a temperature of -70°F.
