The CDI page without a direct-to destination.
The direct-to confirmation page allows you to
verify the destination’s latitude/longitude, facility
name or city/region by highlighting the position
field and rotating the INNER knob.
The GNC 300 uses direct point-to-point navigation to guide you from takeoff to
touchdown in the IFR environment. Once a destination is selected, the unit will pro-
vide 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
direct-to (
D
) key.
To select a direct-to destination:
1. Press the
D
key. The CDI page will appear with the destination field flashing.
2. Rotate the
K
knob to enter the first letter of the destination waypoint identifier. The desti-
nation 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 (see right).
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.
