Preflight Test Determines, Before Takeoff,
that the System is Operating Normally.
With power on, a!l circuit breakers in,
and engine running, allow
3
minutes for the
gyros
to
come up
to
speed.
Make sure you are in slaved gyro mode
by confirming the status on the
KA
51
B
Slav-
ing Meter and compare the compass card on
the KPI 552 or KI 525A with your magnetic
compass.
With no modes engaged, depress the
Preflight Test button on the Mode Controller.
All modes will be annunciated on the Annun-
ciator Panel, including the 3 Marker lights, and
the red Autotrim light will flash. At least four and
not more than six flashes must be be observed
to
indicate proper operation of the Autotrim
monitor f.eature. The KCI 310 computer flag
will also come into view. (Figure 1)
For attitude indicator test, push the test
button on the KCI
310
front panel. The attitude
and compass flags will appear and the pic-
torial horizon will display a climbing right turn.
(Figure 2)
The KI 256 FCI does not have a computer
or attitude flag or attitude test since the gyro is
air driven.
The pilot first engages the Flight Director
to
activate the Command V-bar. Then he
engages the Autopilot. The Autopilot will not
engage when the Flight Director is not
operating.
Now depress the CWS switch, center the
display on the Flight Command Indicator and
release the CWS switch. Then apply force
to
the controls
to
determine if the Autopilot can
be overpowered.
CAUTION:
Operation of the Autopilot on the
ground may cause the autotrim
to
run because
of back force generated by elevator down-
springs
or
pilot induced forces.
Some aircraft have preflight test sequen-
ces required in addition
to
the general pro-
cedures described here. See the
FAA
approved
Aircraft Flight Manual Supplement for
your
particular aircraft for details.
IMPORTANT:
This pilot Guide provides a
general description of the various operational
characteristics of the KFC 250 Flight Control
System.
However, operation of the system
should not be attempted without first
reviewing
your
FAA
Approved Aircraft
Flight Supplement Manual for complete
system familiarization and limitation.
