AFCS GROUND TEST
This momentary switch is used to ini-
tiate the SCAS/AP System preflight
test, if desired, after the initial test
that occurs at system power up.
Preflight test must be run prior to
attempting system engagement.
SCAS/AP engagement will be disal-
lowed in any axis that has not suc-
cessfully passed preflight test. The
system will allow engagement and
use of any available axis (roll, pitch,
and/or yaw) that has passed.
SCAS & AP PWR/OFF
Depressing the SCAS & AP
PWR/OFF switch will turn power on
or off to the SCAS/AP system.
Power is available to the system
when the OFF annunciation is not
illuminated.

TEST/BRT/DIM (AFCS LAMP
TEST)
Moving the TEST/BRT/DIM Switch,
located on the overhead panel below
the Emergency Bus 1 Breakers, to
the test position will invoke an AFCS
test function that will turn on the
annunciators in the KMS 541 Mode
Select Panel. These annunciations
shall remain on as long as the switch
is held in test position up to a maxi-
mum of 15 seconds. This lamp test
function can be invoked any time
desired by the pilot and has no effect
on mode operation. An automatic
lamp test function is performed upon
power up of the Mode Select Panel
and will turn on all MSP annuncia-
tors for approximately 2 seconds
immediately after power is applied.
These annunciators may also be
turned on by a special test bit from
the FCC during part of its preflight
testing. See Bell Helicopter 430
Flight Manual for other functions
activated by this switch in the test
position.
