Because the GNC 250 relies on a NavData card for most waypoint information,
there may be instances when waypoint information is not available for use. Locked
waypoints exist when a waypoint contained in a route or used as a proximity way-
point is not contained on the NavData card, or no card is inserted in the unit. If this
condition exists, you’ll be alerted with a ‘Proximity wpt locked’, ‘Route wpt locked’ or
‘Wpt comment locked’ message when the unit is powered up. The identifier of a
locked waypoint will be replaced with a ‘lockd’ message, which indicates you cannot
obtain waypoint information or navigate to the waypoint. The identifier of a locked
waypoint may be displayed by highlighting ‘lockd’ and pressing ENT. Locked way-
points may be deleted from routes, the user waypoint list or the proximity waypoints
list by following the instructions in the appropriate section.
The waypoint scanning feature provides a fast way to scan through airports,
VORs, NDBs and intersections in the database by identifier, facility name or city.
Waypoint scanning may be used from any blank identifier field in the GPS window.
To enter a waypoint by scanning the identifier, facility name or city:
1. With the cursor over a blank identifier field, press
W
. If the identifier field is not blank,
highlight the field with the flashing cursor and press
\
before pressing
W
.
2. Use
O
to highlight the waypoint category you wish to scan.
3. Press
E
to activate the scanning mode.
4. Rotate
O
to place the flashing cursor over the field you want to scan (identifier, facility
or city name).
5. Use
K
and
O
to enter the letters of the identifier, city or facility name. The GNC 250
will scan the database and display the first waypoint that matches your entry.
6. Press
E
to accept the waypoint, and
E
again to confirm the waypoint for the
function being used.
