Turning in NAV mode
When your vessel reaches the arrival circle for a waypoint, the autopilot will give an audible
warning and display a dialog with the new course information.
The turn radius used is defined in the turn parameters for the work profile in use. Refer "Turn
settings" on page 34.
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. See "Course change limit
(Not applicable for ECDIS Track steering)" on page 35.
If the required course change to the next waypoint is less than the course change limit, the
autopilot will automatically change the course. The dialog will disappear after 8 seconds
unless cleared by the PORT/CANCEL key.

shows the offset in relation to the track.
The system will remain in track offset mode as long as there is

to 0 (zero).

Track steering

With AP70/80 software release 1.2 the AP80 system and a Simrad CS68 ECDIS forms a fully
type approved Track steering system according to IEC62065 ed.1.
The routes are planned on and commanded by an ECDIS (Electronic Chart Display
Information System). When the system is installed and configured as described in this section,
you can start a route on the ECDIS and make the AP80 automatically keep the vessel on this
route.
The Track feature is only available after unlocking it using a key obtained from Navico. The
unlock mechanism resides in the autopilot computer board. Only after enabling this feature,
the autopilot system can form part of a certified track control system.
Refer to the Type approval certificate on the product web site for details:
