NAVIGATION (NAV) MODE
USING THE KG 107/Kl206
INDICATORS (VOWRNAV)
In the navigation (NAV) mode, the
autopilot intercepts and tracks VOR and
RNAV courses.
KAP 150 currently in the HDG mode):
To operate in the NAV mode (with the
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 OBS to the desired course.
3. Depress the NAV button on the KC
191. (HDG will remain illuminated and
NAV will flash to signify that the NAV
mode is armed.)
NOTE: If the NAV mode is selected with the
aircraft level within
i4
degrees and within
2-3 dots of course deviation, NAV arm
mode will be bypassed and the NAV mode
will engage directly.
4. Within five seconds, move the heading
"bug" on the KG 107 to the same mag-
netic heading as the selected course
on the CDI.
5. The autopilot will fly an automatic 45
degree intercept heading until within
the capture zone,* then intercept and
fly the desired course.
6. The autopilot will bank as necessary to
maintain course.
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.
*The capture point will vary depending on
the angle of intercept and the rate of
change of VOR/RNAV radials.
