11.1 Course Deviation Indicator overview
The Course Deviation Indicator (CDI) gives a graphical
representation of your vessel’s course in a ‘rolling road’ format.
With your display receiving accurate heading and position
information, you can use the Course Deviation Indicator (CDI) to
monitor your course and accurately steer to a target waypoint.
The CDI application shows a ‘rolling road’, which represents a width
of sea equal to the Cross Track Error (XTE) limits that you have
specified in the Setup menu. As you travel towards the target
waypoint, the checkered pattern and the waypoint will move down
the screen at a rate proportional to your boat’s speed. Navigation
data is displayed alongside or below the rolling road.
The CDI application is pre-configured to display the CDI graphic.
You can customize the panel to display any available data.
