The GNC 250’s extensive waypoint database makes it possible for several way-
points to share the same identifier. To ensure that you are selecting the waypoint
desired, the GNC 250 will always offer the
waypoint confirmation page
(which
shows the waypoint’s position) when an identifier is entered for a particular function.
To accept the waypoint position:
1. Press
E
with the cursor over the ‘ok?’ prompt.
To reject the waypoint position:
1. Press
\
with the cursor over the ‘ok?’ prompt.
Once a waypoint has been accepted or rejected, the previous page will be dis-
played. If there is more than one waypoint available for a selected identifier, the GNC
250 will display a duplicate waypoint page for you to choose the desired waypoint.
The waypoint identifier and number of duplicates will be shown at the top of the
page, with the waypoint type and region of each duplicate indicated below. The way-
points listed are sorted by the distance from your present position.
To scroll through additional duplicate waypoints:
1. Rotate
O
with the flashing cursor active, or
K
with the flashing cursor inactive.
To select the desired waypoint from the duplicates list:
1. Activate the flashing cursor and rotate
O
to highlight the desired waypoint.
2. Press
E
. The waypoint confirmation page will appear.
3. Press
E
over the ‘ok?’ prompt to accept the waypoint or
\
to reject the waypoint
and return to the duplicate waypoints list.
