PROCEDURES

The automatic switch from GPS to VLOC 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
manually, it does 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, as described in Section 10.4
‘CDI Scale/Alarms’. (The factory default setting is ‘Auto’,
which enables the automatic switch to VLOC.)
Selecting an ILS Approach
This example uses a flight from Laughlin Bullhead
(Arizona) International to Flagstaff Pulliam (KFLG) and
selects the ILS runway 21 approach. ‘SHUTR’ intersection
is selected as the IAF, which includes 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 (refer to Figure 6-73 for the following
steps). DO NOT USE FOR
