CDI (GNS 430W Only)
Selection Description
GPS
The GNS 430W CDI button is in the GPS state, and the GPS
ANNUNCIATE output is active. This annunciator output may be
required to be active for some installations.
VLOC The GNS 430W CDI button is in the VLOC state, and the VLOC
ANNUNCIATE output is active.
NOTE
If it is desired to disable the GNS 430W CDI key, press MENU on the MAIN CDI/OBS
CONFIG page and select “Ignore CDI Key?”. This causes the field above the CDI key to
always display GPS, regardless of CDI key presses. This may be necessary for certain
EFIS systems where navigation sensor selection must be accomplished on the EFIS or its
control panel.
OBI SOURCE (GNS 430W Only)
Selection Description
Always GPS
The MAIN King Serial OBI outputs are always GPS. This is useful if it
is desired to switch a Bendix/King KI 229 or KNI 582 RMI pointer
independently from the GNS 430W CDI button.
Track CDI The MAIN King Serial OBI outputs are GPS or VOR, and switchable
by the GNS 430W CDI button. This is useful if it is desired the
Bendix/King KI 229 or KNI 582 RMI pointer to display the same
navigation source as the GNS 430W CDI outputs.
V-FLAG STATE (Main software version 3.20 or later)
Selection Description
Declutter
Whenever vertical deviation is invalid, the vertical deviation bar is
parked in the maximum UP position and the vertical flag is removed
from view, except in the following cases: (i) the CDI is in VLOC mode
and an ILS frequency is tuned, or (ii) the CDI is in GPS mode and a
GPS approach with vertical guidance is active. In these cases,
whenever the vertical deviation is invalid, the vertical deviation bar
parks in the centered position and the vertical flag is shown.
Normal Whenever vertical deviation is invalid the vertical deviation bar parks
in the centered position and the vertical flag is shown.
