4.3.7.2 Procedure Turn for Glide-slope Approach
1. a. Tune navigation radio to ILS frequency.
b. Follow the procedure(s) for LOC Approach Intercept and Tracking
in this manual.
2. a. If a procedure turn is required, enter the procedure turn above the
published altitude.
b. Upon entering the inbound procedure turn sequence, press the
VS Mode switch.
c. Rotate the VS SELECTOR knob to establish the desired rate of
descent to reach approach altitude at completion of the procedure
turn.
d. Upon reaching approach altitude, press the ALT Mode switch.
e. When the NAV Mode switch is pressed, and if the aircraft is below
the glide-slope, the APR and GS annunciations will illuminate
along with the ALT annunciation.
f. Upon capture of the glide-slope, the ALT annunciation will
extinguish. (Ref. 4.3.7 Glide-slope Intercept and Track).
3. a. If a circling or straight-in approach to the ILS course is established,
descend to approach altitude well in advance of reaching the
Outer Marker.
b. Upon reaching approach altitude, press the ALT Mode switch.
c. Upon capture of LOC course, NAV, APR, ALT, and GS will illuminate
if all conditions for glide-slope operation are met (Ref. Glide-
slope Operation). This signifies automatic arming of the glide-
slope function.
d. Upon glide-slope capture, the ALT annunciation will extinguish,
signifying GS capture.
NOTE:
If the final approach flown locates the aircraft above
the glide-slope prior to reaching the Outer Marker,
follow the procedure outlined in the text on Manual
Arming of the glide-slope.
