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.
20 maj 2024 · Finally, the new Frankfurt service is shown in the gold that formed half of the inaugural aircraft's striped livery. References and additional information: The Great Circle Mapper displays maps and computes distances along a geodesic path. It includes an extensive, searchable database of airports and other locations.
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 shortest distance ...
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 winds and fixed compass headings. The development of steamships in the 19th century allowed ...

Ships and aircraft usually follow the great circle geometry to minimize distance and save time and money. For instance, the above map shows the shortest path between New York and Moscow (about 7,540 km). This path corresponds to an air transportation corridor. Air travel over the North Atlantic between North America and Europe follows a similar ...
15 sie 2020 · Great Circle Mapper – also known as GCMap or GCM – is a tool I regularly use. It provides a wealth of information on airports and the distances between two or more destinations. It is a particularly useful tool for flyer programs of airlines whose pricing is linked to the distance travelled. It’s the case with British Airways Executive ...
