departures are offered for the nearest airport.)

assumes you will receive vectors to the final course segment of the approach and will provide
navigation guidance to intercept this final course.)

will add the procedure to the flight plan without immediately using it for navigation guidance.
This allows you to continue navigating the original flight plan, but keeps the procedure available
on the active flight plan page for quick activation when needed.)
7. For VOR and ILS approaches, the standby field of the VLOC window is automatically tuned to
the proper frequency. To activate the frequency press V . To display VLOC course information
on the external CDI (or HSI) press C and verify that “VLOC” is displayed at the bottom left
corner of the screen, directly above the C key.
8. For precision approaches and some non-precision approaches, a reminder window will appear
indicating that GPS guidance on such approaches is strictly for monitoring only—use the VLOC
receivers and external CDI (or HSI) for primary navigation. To confirm this reminder, highlight
“Yes?” and press E .
CDI Key
The GNS 430’s C key is used to couple the GPS or VLOC receiver to the external
CDI (or HSI). When the external CDI (or HSI) is being driven by the GPS receiver,
“GPS” will appear at the bottom left corner of the page, directly above the C key.
When the external CDI (or HSI) if being driven by the VLOC receiver, “VLOC” will
appear instead.
To couple the external CDI (or HSI) to the GPS receiver or VLOC receiver, press C
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 on page 86.
