SYSTEM
DESCRIPTION
AND
OPERATION
1. KFC 150 SYSTEM KC 192 AUTOPILOT COMPUTER - Complete Flight
Director and Autopilot Computer, including system mode
annunciators and system controls.
2. YAV DAMPER (YD) ANNUNCIATOR - Illuminates continuously when
the optional Yaw Damper is engaged.
3. MODE ANNUNCIATORS - Illuminate when a mode is selected by
the corresponding mode selector button (PUSH ON - PUSH
OFF).
4. GLIDESLOPE (GS) ANNUNCIATOR - Illuminates continuously
whenever the autopilot is coupled to the glideslope signal.
The GS annunciator will flash if the glideslope signal is
lost (GS flag in CDI or absence of glideslope pointers in
KI 525A). The autopilot reverts to pitch attitude hold
operation. If a valid glideslope signal returns within six
seconds, the autopilot will automatically recouple in the
GS mode. If the valid signal does not return within six
seconds, the autopilot will remain in pitch attitude hold
mode until such time that a valid glideslope returns and
the aircraft passes thru the glideslope. At that point-i;s
couple will re-occur.
S.
TRIM VARNING LIGHT (TRIM) - Illuminates continuously
whenever trim power is not on or the system has not been
preflight tested. THE TRIM warning light illuminates and
is accompanied by an audible warning whenever a manual trim
fault is detected. The Manual Trim System is monitored for
the Trim Servo running without a command. The TRIM warning
light will illuminate and be accompanied by a steady
audible tone whenever an autotrim failure occurs. The
autotrim system is monitored for the following failures:
trim servo running without a command; trim servo not
running when commanded to run; trim servo running in the
wrong direction. The Trim Circuit Breaker may be cycled
off to silence the continuous tone but the trim fail light
will remain on. Manual Electric Trim may be used but the
autopilot should not be engaged.
