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.

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.
The Great Circle Mapper (www.gcmap.com) began in 1996 as a free tool for visualizing the shortest path between airports around the globe—a geodesic, commonly known as the great circle path—and for computing the distance along this path. A comprehensive database containing over 40,000 airports and other facilities allows users to generate ...
The great circle g (green) lies in a plane through the sphere's center O (black). The perpendicular line a (purple) through the center is called the axis of g, and its two intersections with the sphere, P and P ' (red), are the poles of g.Any great circle s (blue) through the poles is secondary to g. A great circle divides the sphere in two equal hemispheres. ...
