4.4 Main
Indicator
4.4.1
Main Indicator Function
The Main Indicator displays both lateral and vertical deviation from selected course, To/From
indications, lateral and vertical flags and superflags.
The “CDI” button on the bezel of the GNS 530W takes the place of remote “NAV/GPS” switches, and is
used to toggle between display of GPS and VOR/ILS navigation display on a remote indicator. The
Navigation source is annunciated on the display above the ‘CDI’ button. The Navigation method is
optionally annunciated externally by connecting to the VLOC ANNUNCIATE output (P5001-1) and
GPS ANNUNCIATE output (P5001-2). GPS and VOR/ILS navigation may be toggled externally when
the CDI SOURCE SELECT input (P5001-73) is momentarily grounded. See Section 4.5 for more
information on the external annunciators and switches.
An OBS resolver connection to the GPS is preferred, but not required. For the GNS 530W, an OBS
resolver typically is connected to the MAIN OBS inputs for use with the GNS 530W VOR receiver.
