CDI PAGE
The CDI Page may be displayed by pressing the NAV key. This page
displays virtually all the information you need to guide your craft.
The CDI (Course Deviation Indicator) is oriented so that the center represents
your position and the CDI hash represents your desired course. You must
steer toward the hash to eliminate cross track error and stay on course. The
to/from arrow in the center of the CDI indicates if you are navigating to the
waypoint (up arrow) or if you have passed the waypoint (down arrow). You
may set the CDI alarm and CDI scale from the Setup Pages (see Sections
4.3 and 4.7).
You may select the type of information you wish to see on each line. To make
a change, place the cursor under the field and press the MORE key until the
appropriate information is displayed. (See Appendix B for an illustration and
further explanation of the selectable navigation information on lines two and
three.)
On line one, you may elect to display a CDI or the active leg (see Chapter 6).
On line two, you may select one of three direction options (desired track,
bearing, or course to steer). You may also select one of three distance
options (steer direction and distance, range, or distance made good).
On line three, you may select one of three direction options (course made
good, track, or turn instruction). You may also select estimated time enroute
or one of two velocity options (ground speed or velocity made good).
