4. 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.

5. As the distance (DIS) to the IAF approaches
zero, the alert is replaced by a turn advisory
(“LT TO 030° NOW”).
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, prepare for the pro-
cedure turn.
8. Turn right to a heading of 075° to initiate the
procedure turn. The GNS 430W will not guide
you through the turn. (The procedure turn is
displayed on the map page and indicated as
the active leg on the default NAV and active
flight plan pages.) The external CDI needle will
start moving to the left.
9. After approximately one minute, make a 180°
left turn to a heading of 255° to intercept
the ILS. The GNS 430W will sequence to
the inbound leg and “DTK 210° NOW” will
appear in the lower right corner of the screen.
CDI coupling will automatically switch from
the “GPS” receiver to the “VLOC” receiver
as you complete the inbound turn. (If the ILS
frequency has not been activated, per step #4,
this automatic CDI switch will not occur.)
10. As the CDI needle starts to center, make a
left turn to 210° to track the ILS approach
course.
