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 a ctivate the ILS fre-
quency (step #4 below), automatic
selection of “VLOC” will not occur.
1. Within 30 nautical miles of KFLG,
the GNS 430 will switch from enroute
mode to terminal mode and the CDI
scale will transition from 5.0 to 1.0
nautical miles, full scale deflection.
2. If you haven’t already activated the
approach (in steps on previous page), be sure to do so when cleared for the approach. See page 69,
step #4 for a description of this operation.
3. As you approach the IAF (SHUTR), a waypoint alert (“NEXT DTK 030°”) will appear in the lower right
corner of the screen.
4. If you haven’t already done so, press
V
to activate the ILS frequency. If you forget this step, the GNS
430 will display a reminder message (within 3 nm of the FAF) to activate the ILS frequency.
5. As the distance (DIS) to the IAF approaches zero, the alert is replaced by a turn advisory (“TURN TO
030°”).
6. Fly the outbound course (030°), keeping the needle centered on the external CDI (or HSI).
7. Once you have flown approximately one minute past SHUTR intersection, the alert message
“START PROC TRN” will appear in the lower right corner of the screen (if you haven’t already begun the
procedure turn).
