B&G Zeus2 Glass Helm CPU - Manual (Page 52)

When the vessel reaches the arrival circle for a routepoint, the autopilot will give an audible
warning and display a dialog with the new course information. If the required course change
to the next waypoint is less than the Navigation change limit, the autopilot will automatically
change the course. If the required course change to next waypoint in a route is more than
the set limit, you are prompted to verify that the upcoming course change is acceptable.
Ú Note: For information about navigation settings, refer to "Navigation settings" on page 42.
Waypoint arrival circle
The Arrival radius defines the point at which a turn is initiated when you are navigating a
route.
The arrival circle should be adjusted according to boat speed. The higher the speed, the
wider the circle. The intention is to make the autopilot start the heading change in due time
to make a smooth turn onto the next leg.
The figure below may be used to select the appropriate waypoint circle when creating the
route.
Example: With the speed of 20 knots you should use a waypoint circle with radius 0.09 nm.
Ú Note: The distance between any waypoints in a route must not be smaller than the radius of
the waypoint arrival circle when using automatic waypoint shift.
WIND mode
Ú Note: The WIND mode is only available if the system has been set up for sailboat in the
Autopilot Installation menu.
Before the WIND mode is started it must be verified that valid input from wind transducer is
available.
Initiate wind steering as follows;
1. Switch the Autopilot to AUTO mode
2. Adjust the boat heading until wind angle is according to the angle you want to maintain
3. Select the mode indication in the autopilot controller to activate the autopilot menu, and
select WIND mode
The set course to steer (CTS) and set wind angle are entered from the compass heading and
the wind transducer at the moment the WIND mode is selected. From that point the
autopilot will change the course to maintain the wind angle as the wind direction may
change.
