The AP9 Mk3 uses the bearing waypoint – waypoint as the initial
heading reference. The XTE is used to update this heading reference
in order to minimise the XTE.
When arrival circle for the next waypoint is reached, the alarm
(sound only) will go on for 4 seconds and the turn will start
immediately. This mode is best to use if ECDIS/ECS/PLOTTER is
connected between GPS and AP9 Mk3, where the APB sentence has
bearing waypoint – waypoint and XTE calculated as tangents to
radius arc. and distance to radius.
When using GPS only, and ECDIS mode is selected, the autopilot will

automatically turn to upcoming waypoints.
Remote Control
The different types of Remote Controls that can be connected to AP9
MK3, have different ways of operation, depending on the system
configuration. When operating a dual station system, there is a slight
difference in the operation of the remote controls if the system
includes an external mode selector.
