6.3 ILS APPROACHES

Precision approaches can be performed with the GNS
430' s built-in VLOC (VOR/localizer/glideslope) receivers.
The GPS receiver can be used for guidance prior to
reaching the final approach fix, but once there, the proper
frequency must be selected on the VLOC Window (left
side of screen) and the CDI output set to 'VLOC'.
The GNS 430 can be set to automatically switch the
external CDI output from GPS to VLOC as the pilot
intercepts the final approach course. When the ILS
approach is activated, the GNS 430 automatically switches
within 1.2 nm left or right of the final approach course.
This switch can take place anywhere from 2.0 to 15.0 nm
from the FAF.
NOTE: When intercepting the approach course
at a distance less than 2.0 nm from the FAF,
the GNS 430 does not automatically switch the
CDI to VLOC. In this case, press the CDI Key to
manually switch from GPS to VLOC.

Figure 6-72 shows multiple locations along the
approach path and the expected CDI selection: GPS or
VLOC. The automatic switch from GPS to VLOC should
occur within the area of the shaded box.
