Flying the ILS Approach

When you "Activate?" an ILS approach, automatic
switching of the external CDI is enabled (unless turned
off from the CDI/Alarms Page). When you are established
on the inbound course to the FAF, the external CDI
guidance will automatically switch from "GPS" (shown
in green text) to "VLOC" (shown in white text). If you
have forgotten to activate the ILS frequency (step #4 below),
automatic selection of "VLOC" will not occur.

Within 31 nautical miles of KFLG, the GNS
430W will switch from en route mode to termi-
nal mode and the CDI scale will transition from
2.0 to 1.0 nautical miles, full scale deflection.
If you haven't already activated the approach
(in steps on previous page), be sure to do so
when cleared for the approach.
As you approach the IAF (SHUTR), a waypoint
alert ("LT TO 030° x S") will appear in the lower
right corner of the screen.
If you haven't already done so, press the VLOC
flip-flop key to activate the ILS frequency. If
you forget this step, the GNS 430W will display
a reminder message (within 2 NM of the FAF)
to activate the ILS frequency.
