Map Page Setup
The automatic zoom feature will automatically
adjust the map display through progressively
lower scale settings as you approach your
destination waypoint.
A scale setting of '200' for airports will display
airport locations on the map display for all scales
from '200' and lower. Airports will not appear on
the map display at a scale setting of '300'.

The map setup page also allows you to control whether or not the various way-
point types and the identifiers for these waypoints are displayed. Settings for each
waypoint type allow you to select the maximum scale at which that feature should be
displayed, or you may turn that waypoint type off for all scales. For example, by set-
ting 'VOR' at 80, VOR waypoints will appear on the map display at all scales from 80
on down, but not at 120, 200 or 300.
