APPROACH (APR) MODE
USING THE KG 107/Kl206
INDICATORS
The approach (APR) mode allows the
autopilot to intercept and track ILS (both
localizer and glideslope) and VOR and
RNAV courses. To operate in the APR
mode (with the KAP 150 currently in HDG
mode):
1. Tune the frequency for the selected
ILS, VOR or RNAV approach.
2. Set the OBS to the final approach
course (front course for ILS even when
flying a back course approach).
3.
Check the heading displayed on the
KC 107 against the magnetic com-
pass and reset if necessary.
4. Depress the "APR" button
on the KC
191. (HDG will remain illuminated and
'APR" will flash to signify that APR
mode is armed.)
NOTE: If
the APR mode is selected with the
aircraft level within
i4
dearees and within
2-3 dots of course deviatkn, APR arm
mode will be bypassed and the APR mode
will engage directly.

5.
Within five seconds, move the heading
"bug" on the KG 107 to the same mag-
netic heading as the selected course
on the CDI.
6. The autopilot will fly an automatic 45
degree intercept heading until within
the capture zone, then intercept and
fly the desired course. (The "HDG"
light will go off and the "APR" light will
illuminate steadily as the APR mode
goes from arm to engage.)
7. The autopilot will bank as necessary
to maintain course.
