6. Turn left to a heading of 160° to initiate the procedure turn. 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 and active flight plan pages.) The CDI needle will start
moving to the right.
7. After approximately one minute, make a 180° right turn to a heading of
340° to intercept the inbound course. The GNS 430 will sequence to
the inbound leg to the FAF, the CDI needle will swing to the opposite
side to provide proper sensing along the final course segment and
“NEXT DTK 025°” will appear in the lower right corner of the screen.
8. As the CDI needle starts to center, make a right turn to 025°—the
final approach course.
9. Within 2.0 nautical miles of the FAF (LYH), the GNS 430 will switch
from terminal mode to “approach” mode. CDI scaling will be tightened
from 1.0 to 0.3 nautical mile, full scale deflection.
10. As you approach the FAF, a waypoint alert in the lower right corner
(‘NEXT DTK 026°’) will appear. Make any course adjustments necessary
for the final course segment (FAF to MAP).
11. As you cross the FAF, the destination sequences to the MAP (“RW03”,
the runway threshold). With the needle centered, fly toward the MAP, observing the altitude minimums dictated
by the approach plate.
12. As you approach the MAP, a waypoint alert (“APPRCHING WPT”) will appear in the lower right corner.
13. As you cross the MAP, “SUSP” will appear above the O key, indicating that automatic sequencing
of approach waypoints will be suspended at the MAP. A “from” indication will be displayed on the CDI
and default NAV page, but course guidance along the final approach course will continue. If a missed
approach is required, use the O key to initiate the missed approach sequence, as
outlined on the following page.
NOTE
When viewing the map page, note that the final course segment is dis-
played in magenta (the active leg of the flight plan always appears in
magenta) and a dashed line extends the course beyond the MAP. The
dashed line is provided for situational awareness only and should NOT be
used for navigation. Follow the published missed approach procedures.
