Abnormal Operation
If an autopilot failure or trim failure is suspected to have occurred, perform the fol-
lowing steps:
1) Firmly grasp the control stick.
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) Reconfigure the aircraft as needed. Substantial trim adjustment may be needed.
4) Pull the appropriate circuit breaker(s) to electrically isolate the servo and solenoid
components.
5) Release the AP DISC Switch.
OVERPOWERING AUTOPILOT SERVOS
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.
Checking autopilot servos during the preflight check:
1) Check for proper autopilot operation and ensure the autopilot can be overpowered.
2) Note the forces required to overpower the autopilot servos.
DATALINK TROUBLESHOOTING
For troubleshooting purposes, check the LRU Information Box on the ‘Avionics Status’ Page
for Iridium Receiver (GSR 56) (optional) or the SiriusXM Datalink Receiver (GDL 69A) (op-
tional) status, serial number, and software version number. If a failure has been detected in the
GDL 69A the status is marked with a red ‘X’.
Viewing the Avionics Status’ Screen:
1) From MFW Home, touch Utilities > Setup > Avionics Status.
2) Touch the LRU Info Tab.
3) Scroll to display the appropriate database information.
4) Touch an LRU to view further information.
» Ensure the installed hardware has an active subscription or account (e.g., Iridium sub-
scription, XM subscription)
» Perform a quick check of the circuit breakers to ensure that power is applied to the ap-
plicable hardware
