Autopilot Engagement - Honeywell KFC 150 Pilot's Manual

If
a change in pitch attitude is desired,
the control wheel steering (CWS) button on
the pilot's control wheel can be used to syn-
chronize the V-bar (in the FD mode with
autopilot disengaged) without removing
your hand from the control wheel.
The vertical trim switch may be used
to adjust the selected pitch attitude up or
down at .9 degrees per second.

CAUTION: Overpowering the Autopilot in
the pitch axis in flight for periods of three
seconds or more will result in the autotrim
system operating in the direction to oppose
the pilot and will, therefore, cause an
increase in the pitch overpower forces, and
if Autopilot is disengaged, will result in a
pitch transient control force. Operation of
the autopilot on the ground may cause the
autotrim to run because of backforce gener-
ated by elevator downsprings or pilot
induced forces.
