Reference Manual Part 2

G-Series Reference Manual 176
15.1 The CDI display
The CDI gives you a ‘rolling road’ representation of your progress,
with navigation data displayed alongside.
The rolling road covers an area of sea that corresponds to the
Cross Track Error (XTE) limits specified in the Setup menu.
Steering instructions
The steering instructions below the rolling road tell you what correc-
tion is needed to maintain your course and arrive at the target
waypoint.
Indicator-arrows either side of the steering instruction (pointing
towards the centre line) tell you how great or small the error is. The
greater the error, the greater the number of arrows.
Correct your course by steering in the direction indicated by the
arrows.
15.2 Using the CDI application
To use the CDI, you need to select a page set that includes a CDI
window. For more information about page sets, see Choosing page
sets on page 25.
