Great circle route, the shortest course between two points on the surface of a sphere. It lies in a plane that intersects the sphere’s centre and was known by mathematicians before the time of Columbus. Until the 19th century ships generally sailed along rhumb lines, which made use of prevailing.

Great-circle navigation or orthodromic navigation (related to orthodromic course; from Ancient Greek ορθός (orthós) 'right angle', and δρόμος (drómos) 'path') is the practice of navigating a vessel (a ship or aircraft) along a great circle. Such routes yield the shortest distance between two points on the globe.
5 lip 2019 · Here’s a definition of what a great circle is: A great circle is a circle on the globe such that the plane passing through the sphere’s center is equal to the circumference of the Earth. Alternatively, a great circle is where the radius is equal to that of the globe representing the shortest distance between two points on the surface of the ...
The shortest distance between two points on a globe is not always a straight line—it’s an arc called a great circle. This complicates long-distance navigation. Rather than stay on a constant heading, pilots must regularly adjust their course to stay on the arc. The great circle effect is most dramatic near the Poles.
5 maj 2015 · Ian Petchenik. Updated: September 22, 2020. We’re often asked why an individual flight is flying a particular route, or put another way—“why did we fly over Greenland?”. Long distance flight paths are designed to be the most efficient way to get from point A to point B on the other side of the world.
29 kwi 2014 · What’s a great circle route? Using a globe and some string is easier. 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 ...
In mathematics, a great circle or orthodrome is the circular intersection of a sphere and a plane passing through the sphere's center point. Any arc of a great circle is a geodesic of the sphere, so that great circles in spherical geometry are the natural analog of straight lines in Euclidean space.
