Great Circle Sailing
This screen allows for the calculation of Great Circle navigation and waypoints.
Without considering factors such as weather, winds, magnetic deviation and currents, the great circle track is the shortest distance between any two places on the surface of the Earth.
To sail a great circle track adjustment of the ship's course is continuous because the great circle track is a curve when plotted on a Mercator Chart.
Once you enter the latitude and longitude for origin and destination, tap 'Calculate' to display the 'true' course and distance.
To get waypoint information, enter the desired longitude limitation in the waypoint section then tap 'Calculate.'
To display waypoint calculations for the entire track in 5-degree intervals, tap the 'Calculate Full Track' button.
