pointing up towards the compass, above the
present position arrow. Distance from the present
position to the waypoint (DIS) shows beneath the
compass on the lower left side of the screen. Next
to the distance box is estimated time enroute
(ETE). This is the estimated time that it will take
you to arrive at the destination, based upon cur-
rent track and ground speed. In the lower right
corner is the course (CRS) box showing the di-
rection from your starting position to the waypoint. Remember, a course
is a proposed path from the starting position to the destination. Track is
your actual direction of travel.
Lines on either side of the present position show the current cross track
error range. Cross track error is the distance you are off-course to the
side of the desired course line. The course line is an imaginary line drawn
from your position when you started navigating to the destination way-
point. It’s shown on the screen as a vertical dotted line. The default for the
cross track error range is 0.20 mile. For example,
if the present position symbol touches the right
cross track error line, then you are .25 mile to the
right of the desired course. You need to steer left
to return to the desired course. You can use the
ZIN or ZOUT keys to change the cross track er-
ror range. A circle depicting your destination (way-
point) appears on the screen as you approach
the waypoint as shown on the screen at right.

This navigation screen shows all navigation in-
formation in large digital numbers. To view this
screen, press the PAGES key, then press the up
arrow key until the “NAV 1” label is highlighted.
While it’s highlighted, press the right arrow key.
The screen shown at right appears. Press the
EXIT key to erase the menu.
This screen is composed of eight digital boxes.
Track (TRK) and ground speed (GS) data are the only ones that show
data if you’re not navigating to a waypoint. If you are navigating to a way-
point, then bearing (BRG), distance to waypoint (DIS), estimated time en
route (ETE), cross track error (XTK), estimated time of arrival (ETA), and
the CDI also operate.
