Autopilot operation | 71
When the Navigation mode is initiated, the pilot will automatically keep the vessel on
the leg. When your vessel reaches the arrival circle for a waypoint, the pilot will give an
audible warning and display an alert screen 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.
For more information about navigation parameters and how to navigate with the NSO,
refer to the Navigation section.
Navigational steering should only be used in open waters. When selecting NAV
mode, the pilot maintains the current set course and prompts the user to accept
the course change towards the destination waypoint.
The waypoint arrival circle
The Arrival radius defines the point at which a turn is initiated when you are navigating a
route.
WP1
WP2
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.
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.
