Flying the Procedure Turn
1. Within 30 nautical miles of the destination
airport, the GNS 430 will switch from “enroute”
mode to “terminal” mode (as indicated in the
lower left corner of the screen). The switch to
terminal mode is accompanied by a gradual
Course Deviation Indicator (CDI) scale transi-
tion from 5.0 to 1.0 nautical miles, full scale
deflection. (See example, top left.)
2. Several miles prior to reaching the IAF
(LYH), you may wish to review the approach
sequence. Press the F key to display the
active flight plan page. Press the small right
knob ( r ), and then rotate the large right knob
( d ) to review each segment of the approach.
When finished, press F again to return to
the previous page.
3. As you approach the IAF (LYH), a waypoint
alert (“NEXT DTK 205°”) 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 (“TURN TO 205°”).
Dial the outbound course of 205° into the CDI
(or HSI) using the OBS knob and initiate a stan-
dard 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 “START
PROC TRN” will appear in the lower right corner of the screen. You may initiate the procedure turn at any
time after receiving this alert message.
