Automatic disengagement is indicated by a flashing red 'AP' annunciation and
an aural alert. Touch to acknowledge or touch Back to acknowledge. Automatic
disengagement occurs due to:
• System failure
• Invalid sensor data
• Inability to compute default autopilot modes

ISENGAGING THE AUTOPILOT WHEN A MALFUNCTION IS SUSPECTED
If an autopilot failure or trim failure is suspected to have occurred, perform the
following steps:
1) Firmly grasp the control wheel.
2) Press and hold the AP DISC Switch. The autopilot will disconnect and power
is removed from the trim motor. Power is also removed from all primary
servo motors and engaged solenoids. Note the visual and aural alerting
indicating autopilot disconnect.
3) Retrim the aircraft as needed. Substantial trim adjustment may be needed.
4) Pull the appropriate Autopilot and Trim Switch (if installed) circuit breaker(s)
to electrically isolate the servo and solenoid components.
5) Release the AP DISC Switch.
O
VERPOWERING
In the context of this discussion, "overpowering" refers to any pressure or force
applied to the pitch controls when the autopilot is engaged. A small amount of
pressure or force on the pitch controls can cause the autopilot automatic trim to run to
an out-of-trim condition. Therefore, any application of pressure or force to the controls
should be avoided when the autopilot is engaged.
Overpowering the autopilot during flight will cause the autopilot's automatic trim to
run, resulting in an out-of-trim condition or cause the trim to hit the stop if the action
is prolonged. In this case, larger than anticipated control forces are required after the
autopilot is disengaged.
