Navigation (Nav, Mode - Honeywell KFC 150 Pilot's Manual

NOTE: You should consider using HDG
select mode just prior to VOR station pas-
sage. If the autopilot is engaged in NAV
mode it may cause erratic maneuvers while
following a rapidly changing course devia-
tion needle as the aircraft flies in the cone
of confusion.
NAVIGATION (NAV, MODE
WOR. RNAV)
The Navigation (NAV) mode provides
guidance to the pilot (or autopilot) in inter-
cepting and tracking VOR and RNAV cours-
es. To operate in the navigation 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 PNI course pointer to the
desired course.
3. Establish the desired intercept angle
by setting the heading 'bug' on the
intercept heading, and activate HDG
mode. ('HDG" light will illuminate.)
4. Depress the "NAV button on the KC
192. ("NAV' light will flash to signify
that the NAV mode is armed.)
NOTE: If the NAV mode is selected with
the aircraft level within
i4
degrees of bank
and within 2-3 dots of course deviation,
NAV/ARM will be bypassed and the NAV
mode will engage directly.
5. The V-bar will command the required
bank to maintain the selected heading
until the capture point* is reached.
Then the V-bar will command a turn to
intercept the course. If the autopilot is
engaged, it will turn to satisfy the com-
mands. (The HDG light will go off as
HDG mode is disengaged, and the
"NAV' light will stop flashing and illumi-
nate continuously as the NAV mode
goes from arm to engage.)
6. The V-bar will continue to command
the required bank to maintain course
with automatic crosswind compensa-
tion and the autopilot (if engaged) will
satisfy those commands.
*The capture point will vary depending on
the angle of intercept and the rate of
change of VOR/RNAV radials.
