Map Page Auto Zoom
An autozoom feature is available which will auto-
matically adjust from an en route range of 200 NM
through each lower range, stopping at a range of
1.0 NM as you approach your destination waypoint.
The autozoom feature is turned on/off from the map
setup page.
The
map page
also displays a background map
showing lakes, rivers, coastlines, highways, railways
and towns. When a map scale is selected below the
lower limit at which the map detail was originally cre-
ated, an “overzoom” indication will appear on the map
display, below the scale reading. “Overzoom” indicates
that the detail at this scale may not accurately repre-
sent actual conditions. If you continue to zoom in to
lower scale settings, “overzoom” will be replaced with
“no map” and the geographic detail is removed from
the map display (but, the airport and navaid detail will
remain).
The “Setup Map?” option allows you to define the
maximum scale at which each map feature will appear.
This provides you with complete control to minimize
screen clutter. You can also quickly remove items from
the map using the
CLR key.
To quickly declutter the map display, press the CLR key
momentarily (as often as needed) to select the desired
amount of map detail.
The right-hand side of the map page includes four
user-selectable data fields. By default, the displayed
data is: destination waypoint name (WPT), desired
track (DTK), distance to destination waypoint (DIS)
and ground speed (GS). Any of these data fields may
be changed to display a different data type. You may
also remove the four data fields from the map to show
a larger map image.
The CLR key allows you to quickly declutter
the map display, providing four levels of
map detail. Note the “-1” and “-2” (“-3” is
also provided) suffix designations above,
indicating each successive declutter level.
Declutter Level Detail
-1 Removes all land data except rivers
and lakes.
-2 Removes all airspace except Prohibit-
ed and Restricted. Also removes NDBs,
Intersections, and User waypoints.
-3 Removes all data except the Active
Flight Plan, Prohibited airspace ,rivers,
lakes, traffic, and lightning data (also
equivalent to “-A” approach mode
decluttering.
