Simrad AP16 Autopilot
The AP16 is designed to steer in "mixed mode" operation. This
combines the straight steering capability of cross track error
(XTE) steering in conjunction with the turning capability of
bearing mode steering (Course To Steer, CTS) and automatic
waypoint shift.
If the AP16 is connected to a navigation receiver that does not

XTE message and steer on Cross Track Error only. In that case
you have to revert to AUTO mode at each waypoint and
manually change set course to equal bearing to next waypoint
and then select NAV mode again.
Press the NAV button to activate the NAV prompt display.
