CDI Key
The GNS 530W’s CDI key is used to couple the
GPS or VLOC receiver to the external CDI (or HSI).
When the external CDI (or HSI) is connected to the
GPS receiver, “GPS” appears at the bottom left corner
of the page, directly above the
CDI key. When the
external CDI (or HSI) is being driven by the VLOC
receiver, “VLOC” appears instead.
To couple the external CDI (or HSI) to the GPS
receiver or VLOC receiver, press the CDI key to
display “GPS” or “VLOC”, as desired.
NOTE:
The external CDI (or HSI) must be coupled
to the VLOC receiver for approaches which are
not approved for GPS. See ILS example in the
Procedures section for more information.
