MODE
ANNUNCIATORS
-111uminates
when
a mode is selected
by the corresponding
mode selector button (PUSH ON - PUSH
OFF) or
when the glide slope (GS)
mode is automatically engaged.
3.
GLIDE
SLOPE (GS) ANNUNCIATOR
-
Illuminates continuously
whenever the autopilot is coupled to
the
glide slope signal. The
GS
annunciator
will
flash if
the glide slope signalis
lost (GS flag in CDI
or absence of glide slope pointers in
KI 525A). The
autopilot
reverts
to
pitch
attitude
hold
operation. If a valid glide slope 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 glide slope
returns
and the aircraft passes
thru the
glide
slope. At
that point
GS
couple will re-occur.
4. TRIM WARNING LIGHT (TRIM)
-
Illuminates
continuously
whenever trim power is
not
on or
the system has
not
been preflight
tested. Flashes and is accompanied
by an audible warning whenever
a manual
trim fault is detected. The TRIM warning light will
illuminate
steady 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
power
switch may be
cycled off to silence the continuous
tone
but
the trim
fail
light will
remain on. The manual electric trim
may
be used but the autopilot
should not be
engaged.
5. AUTOPILOT
ANNUNCIATOR
(AP)
-
Illuminates continuously
whenever
the
autopilot
is
engaged. Flashes approximately
12 times
whenever the autopilot
is disengaged
(an
aural alert
will
also sound
for 2
seconds).
6. AUTOPILOT
ENGAGE
(AP
ENG)
BUTTON
-
When
pushed,
engages
autopilot if all logic conditions
are met.
7. PREFLIGHT TEST (TEST) BUTTON
-
When
momentarily
pushed, initiates preflight test sequence
which
automatically
turns
on
all annunciator lights, tests the roll and pitch rate monitors, tests
the autotrim
fault
monitor, checks the manual trim drive voltage
and
tests all autopilot
valid and
dump
logic. If the pieflight
is
successfully passed, the AP annunciator light will
flash for approxi-
mately 6 seconds
(an
aural tone
will
also sound simultaneously with
the annunciator
flashes). The autopilot
cannot be engaged untilthe
preflight
test is successfully passed.
