190-00357-00 Rev E
At approximately one minute past the IAF, an alert message
(“Left to 160° in x sec”) reminds you to begin the procedure
turn.
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. (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 starts 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 500W-series unit
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.
8. As the CDI needle starts to center, make a right
turn to 025° — the final approach course.
Procedure turn, inbound. The CDI needle swings to the oppo-
site side for proper sensing and “Next DTK 025° now” appears.
Turn to the new heading as the needle begins to center.
9. When within 45° of the final approach
course and the FAF is the TO waypoint, the
500W-series unit switches from terminal mode
to “approach” mode. CDI scaling is tightened
from 1.0 NM full scale deflection to either
0.3 NM or 2° full scale deflection whichever is
less at the FAF. The change occurs over 2 NM
and is completed by the FAF.
10. As you approach the FAF, a waypoint alert in
the lower right corner (“Next DTK 026° in x
sec”) appears. 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 (“RW04”, the runway threshold).
With the needle centered, fly toward the MAP,
observing the altitude minimums dictated by
the approach plate.
