System Overview
1-7
panel and mode annunciation on the PFD changing to green and
flashing for up to 10 seconds.
Note that the engaged (green) autopilot mode annunciators will
also flash when in underspeed or overspeed conditions. This
flashing is intended to gain the pilot’s attention and to indicate
that while the modes are still engaged (green), the underspeed or
overspeed condition may be affecting the system’s ability to hold
the target value. As soon as the underspeed or overspeed
condition is no longer true, the annunciators stop flashing and the
system reacquires the target values as required.
MANUAL ELECTRIC TRIM DISCONNECT
Use of the manual electric trim (MET) in the pitch axis via the
cockpit controls will result in the autopilot disconnecting and then
the trim running as commanded by the MET control.
NOTE
Trim Behavior in Cirrus Aircraft
For Cirrus aircraft equipped with a pitch servo,
actuating the trim switch will disconnect the AP. For
Cirrus aircraft that are equipped with pitch trim only,
actuating the trim switch will have no effect during
autopilot operations (trim will not adjust and the AP
will not disengage). For predictability of results,
pilots of Cirrus aircraft should therefore determine
whether the aircraft is equipped with a pitch servo or
pitch trim before actuating the trim switch in IMC
conditions.
