6) Turn the large right knob to highlight ‘Load?’
or ‘Activate?’ (Figure 9-8) and press the ENT
Key. (‘Load?’ adds the procedure to the
flight plan without immediately using it for
navigation guidance. This allows the pilot to
continue navigating the original flight plan, but
keeps the procedure available on the Active
Flight Plan Page for quick activation when
needed.)
Figure 9-8 Highlight ‘Load?’
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 the
VLOC Flip-flop
Key. To display VLOC
course information on the external CDI (or
HSI) press the
CDI
Key and verify that ‘VLOC’
is displayed at the bottom left corner of the
screen, directly above the
CLR
Key.
8) For precision approaches and some non-
precision approaches, a reminder window
appears 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 the
ENT
Key.
CDI Key
The GNS 430’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 being driven by the GPS
receiver, ‘GPS’ appears at the bottom left corner of the
page, directly above the
CDI Key. When the external CDI
(or HSI) if 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 (Figures 9-9 and 9-10).
