Operating The Kap I00 System; System Self-Test - Honeywell KFC 150 Pilot's Manual

OPERATING THE KAP I00 SYSTEM
When initially powered (no modes
selected), the KAP 100 will display aircraft
attitude on the KG 258 and unslaved head-
ing on the KG 107. Align heading to the
magnetic compass by pushing and rotating
the knob on the lower left of the KG 107
and update it periodically to correct for pre-
cession.
System Self-Test
The
KAP
100 system incorporates a
system self-test function which is activated
by a test button on the KC 190 Mode
ControllComputerlAnnunciator. The test
must be performed before the autopilot can
be engaged. The test determines, before
takeoff, that the system is operating normal-
ly. To perform the test, momentarily push
the test button:
1. All annunciator lights, the trim light and
autopilot light 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 'AP' 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 190 display will go blank.
The test checks all digital computing
capability, the disconnect capability of the
autopilot, and the failure annunciator sys-
tem. CAUTION: If the trim legend flashes
at the end of the test it indicates there is a
failure in the King Manual Electric Trim.
(See a qualified King Service Agency for
repair.)
*On systems with King manual electric trim
only.
