To blank a waypoint field, highlight the field and
press the
\
key.
Because the GNC 250XL 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, used as a proximity waypoint
or with a comment 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
E
. Locked waypoints may be deleted from routes, the proximity waypoints list or
waypoints with comments page by following the instructions in the appropriate
section of this manual.
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 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 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 250XL
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.
