Stabilator System Components--
a.
Stabilator powered by tandem
Simplified
hydraulic actuator: failure of either
hydraulic system will not affect
operation
b.
Stabilator trim actuator consists of
main and standby motor
(1) Main motor powered by 28 VDC
essential bus. Operated by trim
switch on control stick
(2) Standby motor powered by 28
VDC generator bus. Used in case
of main motor failure. Controlled
by STBY STAB TRIM switch
NOTE: Both motors are
deenergized by travel limit
switches. Lifting the STBY STAB
TRIM switch guard disables the
main trim motor and allows use of
the standby trim switch.
