Description
This gnomonic planning chart from the British Admiralty covers the North Atlantic and is specifically designed for calculating and visualizing great circle routes between Europe, North America and adjacent seas. The chart is primarily used in the planning phase of long-distance sailing across the Atlantic.
In a gnomonic projection, great circles appear as straight lines, which makes the map particularly suitable for strategic route selection before sailing. The map provides an overall picture of geographical contexts and distances, but is not intended for operational navigation or use near coasts and harbors.
This chart is suitable for professional navigators, long-distance sailors and maritime operators working with route planning over open seas, either as a supplement to operational nautical charts or as a support tool in navigation preparation and training.
