Refer to Figure 6-16 for the following steps:
6) Course guidance is provided relative to the
outbound leg from the FAF. No guidance
through the procedure turn itself is given. (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.) The
CDI needle starts moving to the right.
7) When turning to intercept the inbound course,
the GNS 430 sequences to the inbound leg to
the FAF, the CDI needle swings to the opposite
side to provide proper sensing along the final
course segment and ‘NEXT DTK 025°’ appears
in the lower right corner of the screen (Figure
6-17).

8) Turn to the final approach course.
9) Within 2.0 nm of the FAF (LYH), the GNS 430
switches from terminal mode to ‘approach’
mode. CDI scaling is tightened from 1.0 to
0.3 nm, full scale deflection.
10) When approaching the FAF, a waypoint alert
(‘NEXT DTK 026°’) appears in the lower
right corner. Make any course adjustments
necessary for the final course segment (FAF to
MAP).
