ILS Approach
430W Only
The automatic switch from GPS to VLOC is not
immediate, but instead occurs gradually to prevent
abrupt CDI changes when coupled to an autopilot.
The CDI selection can also be changed manually by
pressing the
CDI key. Once the switch from GPS to
VLOC has occurred, either automatically or manu-
ally, it will not automatically switch again until the
approach is reactivated or another approach is
selected. To prevent automatic ILS CDI selection,
choose the “Manual” ILS CDI setting. (The factory
default setting is “Auto”, which enables the automatic
switch to VLOC.)

Selecting an ILS Approach
For this example, we’ll use a flight from Laughlin
Bullhead (Arizona) International to Flagstaff Pul-
liam (KFLG) and select the ILS runway 21 approach.
“SHUTR” intersection will be selected as the IAF,
which will include an outbound leg and a procedure
turn. Of course, vectors-to-final could also be selected,
as previously described for the non-precision approach
examples.
1. Select Flagstaff Pullam (KFLG) as your des-
tnaton, va the
direct-to
key or as the last
waypont n a flght plan.
2. Press the
PROC
key and select the “ILS 21”
approach.
3. From the transtons wndow, select “SHUTR”
as the IAF. Also, select “Load?” (or “Actvate?”,
f already cleared for the approach).
