ELEVATOR MISTRIM
ELE or ELE Annunciator displayed
Indicates a mistrim of the elevator while the autopilot is engaged. The servo is providing force in the
indicated direction. The autopilot will normally trim the airplane as required. However, during rapid
acceleration, deceleration, configuration changes, or near either end of the elevator trim limits,
momentary illumination of this message may occur. If the autopilot is disconnected while this
message is displayed, high elevator control forces are possible. The following procedure should be
followed:
IF MOMENTARILY DISPLAYED
Indicates autopilot pitch servo torque has reached a pre-determined level as a result of elevator
trim not keeping up with demand. This is normal in some maneuvers or near either end of the
pitch trim limits.
