7.3.3. Stabilator
The CTLS has a drag-optimized stabilator with an anti-servo tab. It is attached to a
fuselage-mounted stabilator pivot bearing. An individually matched counter-weight
with which the stabilator is completely mass-balanced is also attached to this bearing.
The anti-servo tab on the trailing edge of the horizontal tail covers 75% of the
stabilizer span. It is aerodynamically optimally attached to the fin by an elastic
composite hinge. It is activated through a mechanical coupling when the stabilizer is
deflected. In this way the anti-servo tab deflects in the opposite direction as the
stabilator, thus improving stabilator effectiveness and generating a proper force
gradient on the control stick.
Warning:
When dismounted or when the controls are disconnected, the anti-servo
tab must never be pushed beyond normal operating limits as this
causes damage to the elastic hinge. We recommend that the trim tab
be clamped with an edge guard or taped to the outside edges to
prevent inadvertent movement.
The stabilizer is activated via a special push-pull cable that runs through the tunnel
and along the fuselage floor. This push-pull cable aligns itself to the fuselage and is
maintenance-free.
