Stabilizer Trim Switches

Provide electrical signal to hydraulic trim control modules for stabilizer trimming. Both switches must be operated simultaneously.

Trim rate varies with airspeed and the number of trim control modules operating.

Switches are deactivated with more than one autopilot engaged, but trip off the autopilot if only one autopilot is engaged.
