3.13.9 AUTOPILOT OR ELECTRIC TRIM MALFUNCTION/FAILURE
NOTE
An autopilot or electric trim malfunction may be recognized
by an unexpected deviation from the desired flight path,
abnormal flight control or trim wheel movement, or flight
director commands which cause unexpected or contradictory
information on the other cockpit displays. It may be
accompanied by the aural autopilot disconnect tone, a red
AFCS, red PTCH, red ROL, red YAW, red AP or yellow AP
indication on the PFD, or a yellow CHECK ATTITUDE on the
PFD. The autopilot and AHRS monitors normally detect
failures and automatically disconnect the autopilot.
Failure of the electric pitch trim, indicated by a red boxed
PTRM flashing on the PFD, may not cause the autopilot to
disconnect. Be alert to possible autopilot out of trim
conditions (see AUTOPILOT OUT OF TRIM procedure
below), and expect residual control forces upon disconnect.
The autopilot will not re-engage after disconnect with failed
pitch trim. If AUTOPILOT OUT OF TRIM ELE indication is
present, expect substantial elevator forces on autopilot
disconnect.
