NAVIGATION
Refer to Figure 6-68 for the following steps.
8) Initiate the procedure turn. The GNS 530 does
not provide guidance through the turn. (The
procedure turn is displayed on the Map Page
and indicated as the active leg on the Default
NAV Page and the Active Flight Plan Page.)
9) After approximately one minute, make a turn
to intercept the ILS. The GNS 530 sequences
to the inbound leg and ‘NEXT DTK 210°’
appears along the bottom of the screen. CDI
coupling automatically switches from the GPS
receiver to the VLOC (Figure 6-69) receiver as
the pilot completes the inbound turn. (If the ILS
frequency has not been activated, per step 4,
this automatic CDI switching does not occur.)

10) Turn to track the ILS approach course.
NOTE: From this point on, primary navigation
is provided by the VLOC receiver. The pilot may
continue to use the GPS receiver for supplemental
navigation guidance only. ALSO, when using an
external CDI (not an HSI), expect reverse sensing
when flying outbound on the approach course
or when flying a backcourse approach.
