Operating The Kfc 150 System; Initial Power On; System Self Test - Honeywell KFC 150 Pilot's Manual

OPERATING THE KFC 150 SYSTEM
Initial Power On
When initially powered (no modes
selected), the KFC 150 will display aircraft
attitude on the FCI and aircraft heading on
the
PNI.
The V-bar will be biased out of
view. The trim light will be lit on the KC 192
as a reminder of the need to perform the
system self-test.
Svstem Self-Test
The KFC 150 system incorporates a sys-
tem self-test function which is activated by a
test button on the KC 192 Mode
Controller/Computer/Annunciator. The test
must be performed before the autopilot portion
of the system can be used, but need not be
performed before using the flight director por-
tion. This test determines, before takeoff, that
the system is operating normally. T o perform a
test - momentarily push the test button. The
following actions will occur:
1. All annunciator lights, the trim light and
autopilot lights will illuminate.
2. The trim light will flash 4 times.
3. The annunciator legends will go blank,
an aural tone will beep (approx. 6
times) and the "AF" light will flash
(approx. 12-13 times) and go off. (If
the AP light fails to flash you will be
unable to engage the autopilot.)
4. The KC 192 display will go blank.
The test checks all digital computing
capability, the disconnect capability of the
autopilot, the auto trim drive and monitor
systems, and the failure annunciator sys-
tem.
CAUTION: If
the trim legend flashes
or remains on at the end of the test it indi-
cates there is
a
failure in the trim system
and the autopilot will not engage. See a
qualified King Service Agency for repair.
