The setup 1 page provides access (via "menu options") to airspace alarms, CDI
scale adjustment, an arrival alarm, units of measure settings, position formats, map
datums and settings for local or UTC time display. When a menu option is selected,
the corresponding page will appear providing access to the various unit settings.
To select a menu option from the setup 1 page:
The following menu options are available:
Airspace Alarms— allows you to turn the controlled / special-use airspace mes-
sage alerts on or off. This will not affect the alerts listed on the nearest SUA page
or the airspace boundaries depicted on the map page. It will simply turn on/off
the warning provided when you are approaching or near an airspace.
An altitude buffer is also provided which "expands" the vertical range above or
below an airspace. For example, if the buffer is set at 500 feet, and you are more
than 500 feet above or below an airspace, you will not be notified with an alert
message; if you are less than 500 feet above or below an airspace and projected to
enter it, you will be notified with an alert message. The default is 200 feet.
