Preflight Procedures
44 June 15, 1996 006-08769-0000
Caution: The Autopilot (AP)
moves the controls during pre-
flight test on the ground or in the
air, and the crew should be pre-
pared for control/main and/or tail
rotor movement.
Caution: Operation of the
Autopilot (AP) on the ground may
cause undesired main rotor or tail
rotor control/movement.
The Bell 430 has preflight test
sequences required in addition to the
general procedures described here.
See the Transport Canada and/or
FAA approved Rotorcraft Flight
Manual for particular details.
Autopilot Automatic Self Test
1. Activate power. When flags dis-
apear alignment and self test is com-
plete. When complete, the HDG and
ATTITUDE flags displayed on the
pilot’s displays will be eliminated.
2. Push SCAS & AP PWR switch
(OFF extinguished).
AFCS preflight test will automatically
start. The system will then annunci-
ate AUTOTRIM (yellow) for mini-
mum of 3 seconds at which time
AFCS DISC (red) will start flashing
and remain flashing unless cleared
for rest of test. The above sequence
is then followed by SCAS and AP
(yellow) on for minimum of 3 sec-
onds followed by AFCS PIT, AFCS
ROL and AFCS YAW (yellow) on for
minimum of 3 seconds. At the end
of the complete preflight test an aural
alert will sound for approximately 2
seconds and all other annunciators
for the selected system shall be
extinguished if the selected system
has passed. If “Attention Getter” is
pressed after AFCS DISC (red) first
starts flashing, it will be cleared but
will turn on again at the end of pre-
flight test. Press the “Attention
Getter” to extinguish the flashing
annunciation if desired. If the crew
desires to reinitiate preflight test, for
any reason after the initial automatic
test cycle, lift guard, press the AFCS
Ground Test switch located to the
right of the AFCS Mode Select Panel
in the pedestal. The AFCS will
repeat the same test sequence as
power up.
3. An aural tone sounds in the
headsets only (no speaker) and the
SCAS and AP annunciators are
removed from IIDS upon successful
completion of flight control preflight
test. Press the attention getter to
remove the flashing AFCS DISC
from IIDS.

GROUND
TEST
Air Data System Self Test
1. Verify correct barometric setting
on the altimeter/vertical speed indi-
cator.
2. Press the PUSH TEST BARO
knob.
a. All segments of the gas dis-
charge displays are illuminated
for approximately 3 seconds.
The illumination can be
extended to 13 seconds by
holding in the PRESS-TO-TEST
button.
b. Red ALT and VS flags come
into view.
c. Vertical Speed bug comes into
view and follows the VS pointer.
d. When the display segments test
has been completed the KDC
481T will set the Altitude Select
display at 28,000 ft. and will set
the displayed aircraft altitude to
26,800 ft. The aircraft’s dis-
played altitude will then ramp up
to the selected altitude at a
3500 ft. per minute rate of climb.
e. As the displayed aircraft altitude
increases the altitude alerter
gives an audio and steady
visual alert annunciation at
27,000 ft. At 300 ft. before the
selected altitude, the visual alert
is extinguished and when the
selected altitude is reached a
flashing visual alert is displayed
briefly.
f. When the aircraft’s displayed
altitude has reached the
selected altitude of 28,000 ft.
there will be a 3 second pause,
after which the aircraft altitude
will ramp down to 27,000 ft. at a
3500 ft. per minute rate of
descent.
g. The Vertical Speed bug will con-
tinue to follow the VS pointer to
the 3500 ft. per minute rate of
descent. The altitude alerter
gives an audio and flashing
visual alert 300 ft. below the
selected altitude. The flashing
visual alert continues until the
aircraft’s displayed altitude
reaches 27,000 ft., when it is
extinguished.
h. At 27,000 ft. the ALT and VS
flags and FAIL will again be dis-
played, and then clear.
i. The aircraft’s density altitude
will be displayed for approxi-
mately five seconds in the
selected altitude window.
