RUDDER TRIM SYSTEM
Rudder trim. see Figure 7-9, is achieved by a trim tab attached to the
lower half of the rudder with a full length piano-type hinge. The trim tab
is actuated by a push-pull rod which is attached to a jack screw type
actuator in the vertical stabilizer. The actuator is driven by cables
attached to the rudder trim wheelan the cockpit control pedestal. The
~ rudder trim tab also acts as a servo tab so that aerodynamic forces on the
tab will move the rudder to the selected position, which reduces the forces
required
to activate the rudder in flight.
