ELEVATOR MISTRIM

(Amber AP LED flashes for 10 seconds, ELE TRM UP or ELE TRM DN displayed in Message Window on

GMC 605 display)

Indicates a mistrim of the elevator while the autopilot is engaged. 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.

Do not attempt to overpower the autopilot in the event of a pitch mistrim. The autopilot

servo will oppose pilot input and will cause pitch trim to run opposite the direction of

pilot input. This will lead to a significant out-of-trim condition, resulting in large control

wheel force when disengaging the autopilot.

Momentary display of the ELE TRIM UP or ELE TRIM DN message during

configuration changes or large airspeed changes is normal.

1. Control Wheel................................................................................................GRIP FIRMLY

Be prepared for significant sustained control forces in the direction of the mistrim

annunciation. For example, ELE TRM DN indicates nose down control wheel force will

be required upon autopilot disconnect.

2. AP DISC / TRIM INT Switch .................................................................PRESS AND RELEASE

3. Manual Elevator Trim .............................................................................RE-TRIM as required

4. The autopilot should be considered inoperative until the cause of the mistrim has been investigated

and corrected. Yaw damper may be re-engaged and used normally.
