PITCH Wheel – Moving the PITCH wheel with the autopilot
engaged changes the pitch attitude in proportion to the rotation rate
of the PITCH wheel and in the direction the wheel is moved. Moving
the PITCH wheel cancels only altitude hold or altitude preselect
capture.
With vertical speed mode or flight level change mode selected on
the mode selector, rotating the PITCH wheel changes air data
reference displayed on the EFIS. The vertical speed or flight level
change modes can be cancelled by pushing the mode button on the
mode selector. If the air data modes are not selected, the PITCH
wheel works as described above. However, for safety, moving the
PITCH wheel has no effect with glideslope captured.
D
BANK LIMIT Button – Selecting the bank limit mode on the
autopilot controller generates a lower maximum bank angle (14_)
while in the flight director heading select mode only.

D
UP or DN (Down) Annunciator – The UP or DN annunciators light
to indicate a sustained request for elevator trim. UP or DN remain
lit as long as the elevator servo is required to hold a significant force
to maintain aircraft attitude.
D
AP Button – The AP button engages the autopilot and yaw damper
simultaneously. When engaged, the AP button lights. The autopilot
can be engaged with the airplane in any reasonable attitude. When
no flight director modes are selected and the autopilot is engaged,
it rolls the aircraft to wings level and holds the existing pitch attitude
and aircraft heading. If any flight director modes are active before
the autopilot is engaged, the autopilot automatically couples to the
flight director modes. The autopilot does not engage unless the
TURN knob is in detent (centered).
If the autopilot and yaw damper are engaged, pushing the AP button
again disengages only the autopilot and leaves the yaw damper on.
D
YD Button – The YD button engages only the yaw damper. If only
the yaw damper is engaged, pushing the YD button again
disengages it. If autopilot and yaw damper are engaged, pushing the
YD button disengages both.
