“Right to 075° in 7 sec” appears in the lower
right corner of the screen to remind you to
initiate the procedure turn.
8. Turn right to a heading of 075° to initiate the
procedure turn. Messages displayed during
turn provide roll steering guidance. (The pro-
cedure 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 starts moving to the left.

NAVIGATION
9. After approximately one minute, a message
will appear for turn advisory (“Left to 255°
in x sec”) to intercept the ILS. The GNS 530W
sequences to the inbound leg and “Left to 210°
now” appears in the lower right corner of the
screen. CDI coupling automatically switches
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 does not occur.)
NOTE: From this point on, primary navigation is
provided by the VLOC receiver. You may continue
to use the GPS receiver for supplemental naviga-
tion guidance only. If automatic CDI switching
is disabled (“Manual” selected), the reminder
message “Select VLOC on CDI for approach” ap-
pears at 3.0 nautical miles prior to the FAF. In this
instance, you must press CDI to manually switch
CDI output to the VLOC receiver and continue the
approach.
The GNS 530W automatically switches from
the GPS receiver to the VLOC receiver as you
complete the turn inbound. The annunciator
above the CDI key switches from “GPS” to
“VLOC”.
10. As the CDI needle starts to center, make a
left turn to 210° to track the ILS approach
course.
