8.2.1.4 Navigating with Great Circle or Rhumb Line
ECDIS provides a feature that allows you to navigate great circle routes. When
you enter a waypoint at a distance greater than 200 NM from the ship’s position
or from the previous waypoint (see chapter 8.2.1.2), ECDIS prompts you with
following message:

of intermediate waypoints

Simulate a Great Circle Route
If you want to simulate a great circle route, you will need to enter the number of
intermediate points to create the route (see Figure: 1
− 15) . These points create
a curved great circle route. You can delete or move these waypoints at your
choice. If you click on
No , ECDIS will simply draw a rhumb line route to the
waypoint.
