h. Autopilot Controller (PC-400) Controls and
Functions.
(1) Pitch Thumbwheel. Rotation of the pitch
thumbwheel with the autopilot engaged results in a
change of pitch attitude proportional to the rotation of
the pitch wheel and in the direction of wheel
movement. Movement of the pitch thumbwheel will
cancel any other previously selected vertical mode.
However, for safety, movement of the pitch
thumbwheel has no effect with the autopilot coupled to
a glideslope signal.
(2) BANK LIMIT Switch. Selection of the
bank limit mode on the autopilot controller provides a
lower maximum bank angle while in the heading select
mode.
LOW will illuminate on the BANK LIMIT switch.
The lower bank limit is inhibited and LOW is
extinguished during NAV mode captures. If heading
select is again engaged, bank limit will again be
illuminated. Pressing
BANK LIMIT when illuminated
will return autopilot to normal bank limits.
(3) SOFT RIDE Switch. Soft ride reduces
autopilot gains while still maintaining stability in rough
air. This mode may be used with any flight director
mode selected.
(4) TURN Knob. Rotation of the turn knob
out of detent results in a roll command. The roll angle
is proportional to and in the direction of the turn knob
rotation. The
TURN knob must be in detent (center
position) before the autopilot can be engaged.
Rotation of the TURN knob cancels any other
previously selected lateral mode.
(5) YD ENGAGE Switch. When the autopilot
is not engaged, the yaw damper may be used by
pressing the
YD ENGAGE switch.
(6) AP ENGAGE Switch. The AP ENGAGE
switch is used to engage the autopilot. Engaging the
autopilot automatically engages the yaw damper. The
autopilot may be engaged with the airplane in any
reasonable attitude.
