The next page available from the GNC 250XL’s
N
key is the
map page
. The
map page displays your present position, using an airplane symbol (in track up
mode) or a position diamond (in other orientation modes), along with nearby air-
ports, VORs, NDBs, intersections, user waypoints and airspace boundaries.
Note
: If
the GNC 250XL is unable to determine a GPS position the present position symbol
will not appear on the map page.
The top left corner of the page indicates the active and standby communica-
tions frequencies — unlike other GNC250XL screens which display both frequen-
cies across the top line — with the active frequency on top.

To change the map scale rotate the
K
knob clock-
wise to increase the scale or counterclockwise to
decrease the scale.
On the map page the active and standby commu-
nication frequencies are in the upper left corner of
the page. The active frequency is on top.
