The following menu options are available:
• ‘Display’ - Allows the pilot to adjust the display for
optimum viewing in any condition. Automatic
backlighting is available which uses a built-in
photocell (at the top left corner of the display
bezel) to make the proper display adjustments
without any user intervention. Automatic contrast
adjustment varies the screen contrast level based
upon current unit temperature. The pilot may
also select manual control of the display contrast
and backlighting of the GNS 430’s display.
• ‘Nearest Airport Criteria’ - Denes the minimum
runway length and surface type used when
determining the nine nearest airports to display
on the Nearest Airport Page. A minimum runway
length and/or surface type may be entered to
prevent airports with small runways, or runways
that are not of appropriate surface, from being
displayed. The default settings are ‘0 feet (or
meters)’ for runway length and ‘any’ for runway
surface type.
• ‘COM Conguration’ - Allows selection of 8.33
kHz or 25.0 kHz COM frequency channel spacing.
NOTE: 8.33 kHz VHF communication frequency
channel spacing is not approved for use in the
United States.
