The GNC 250XL uses direct point-to-point navigation to guide you from takeoff
to touchdown in the VFR environment. Once a destination is selected, the unit will
provide speed, course and distance data based upon a direct course from your present
position to your destination. A destination can be selected from any page with the
D
(
direct-to
)
key
.
To select a direct-to destination:
1. Press the
D
key. The CDI page will appear with the destination field highlighted.
2. Rotate the
K
knob to enter the first letter of the destination waypoint identifier. The des-
tination waypoint may be an airport, VOR, NDB, intersection or user waypoint, as long as
it is in the database or stored in memory as a user waypoint.
3. Rotate the
O
knob to the right to move the cursor to the next character position.
4. Repeat steps 2 and 3 to spell out the rest of the waypoint identifier.
5. Press
E
to confirm the identifier. The direct-to confirmation page will appear.
6. Press
E
to confirm the destination.
Once the direct-to destination is confirmed, the
CDI page
will appear with the
destination indicated in the lower left hand corner of the screen. Your present speed
and track over the ground, and the distance and estimated time enroute to your desti-
nation are also displayed. The graphical CDI, located at the top left of the screen, dis-
plays your position relative to the desired course and provides turn anticipation and
waypoint messages during route navigation.

When a destination is selected the direct-to
confirmation page appears to verify the
destination you selected.

active route appears blank, except for ground
speed (GS) and track (TRK) figures.
