Chapter 13:Using the Course Deviation

13.1 Introduction

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 is pre-configured to display the CDI graphic. You can customize the
panel to display any available data.

13.2 The CDI screen

The CDI gives a graphical representation of yours boat's course in a 'rolling road'
format.
The 'rolling road' 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.
