Procedure Turn Approach
3. As you approach the IAF (LYH), a waypoint alert
(“LT TO 205° x S”) will appear in the lower right
corner of the screen. As the distance (DIS) to
the IAF approaches zero, the alert is replaced
by a turn advisory (“LT TO 205° NOW”). The
unit will guide you automatically, or you can
dial the outbound course of 205° into the CDI
(or HSI) using the OBS knob and initiate a
standard rate turn to this course heading.
4. Fly the outbound course, keeping the CDI
needle centered.
5. Once you have flown approximately one minute
past the FAF (LYH), the alert message “
LT TO
160° x S
” will appear in the lower right corner
of the screen. The unit will sequence to the
inbound leg when established inbound.
NOTE:
You may manually perform any type of
procedure turn in accordance with the AIM and
the charted procedure. However, the unit displays
a map of, and provides roll steering for, a 45/180
procedure turn. If you manually complete the
entire procedure turn prior to the unit’s initial
outbound turn alert, software versions prior to
3.20 may sequence to the inbound leg but enter
SUSP mode. In that case, press the OBS key to
resume automatic sequencing.

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 will start moving to the right.
