NAVIGATION (NAV) MODE
USING THE KG 107/Kl206
INDICATORS (VOR, RNAV)
In the navigation (NAV) mode the
autopilot intercepts and tracks VOR and
RNAV courses. To operate in the NAV
mode (with the KAP 100 currently in HDG
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 OBS to the desired course.
3. Depress the NAV button on the KC
190. (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 *4 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 desir3d.course. The "HDG" light
will go off and the 'NAV' light will illumi-
nate steadily as the 'NAV" mode goes
from arm to engage.
6. The autopilot will bank as necessary to
maintain course.
NOTE: You should consider using HDG select
mode just prior to VOR station passage. If the
autopilot is engaged in NAV mode it may
cause erratic maneuvers while following a
rapidly changing course deviation needle as
the aircraft flies in the cone of confusion.
NOTE:
For system limitations refer to the Flight
Manual Supplement for your particular aircraft.
