MVIG4Tlm IMW MODE USING
In the navigation (NAV) mode, the
autopilot intercepts and tracks VOR and
RNAV courses. To operate in the NAV
mode:
1. Tune the frequency for the selected
VOR (or VORTAC) station. For RNAV,
set in the waypoint distance and VOR-
TAC radial.
2. Set the desired course on the KI 525A
PNI.
3. Establish the desired intercept angle
by setting the heading 'bug' on the
intercept heading and activate HDG
mode. The KAP 100 can perform all-
angle intercepts when using the KI
525A PNI. (HDG light will illuminate.)
4. Depress the NAV button on the KC
190. (NAV light will flash to signify that
NAV mode is armed.)
NOTE: If the NAV mode is selected with the
aircraft level within *4 degrees and within
2-3 dots of course deviation, NAV arm
mode will be bypassed and the NAV mode
will engage directly.
5. The autopilot will fly the selected
heading until entering the capture
zone,* then turn to intercept the select-
ed course. The HDG light will go off
and the NAV light will illuminate steadi-
ly as the NAV mode goes from arm to
engage.
6. The autopilot will bank as necessary to
maintain course.
*The capture point will vary depending on
the angle of intercept and the rate of
change of VORRNAV radials.

NOTE:
You should consider using HDG
select mode just prior to VOR station pas-
sage. If the ahtopilot is engaged in NAV
mode it may cause erratic maneuvers while
following a rapidly changiag &ouise devia-
tion needle as the aircraft flies in the cone
of confusion.
