3. FLIGHT CONTROLS
The ailerons, elevator and wing flaps are operated through control rods, while the
rudder is controlled by cable. Aircraft flight controls are operated through control
stick and rudder pedals.
Stabilator
Longitudinal control acts through a system of push-rods and is equipped with a trim
tab. The control and the movement of the stabilator is transmitted through the
connecting rod to the transmission lever and from this to the rod that, passing
through the tail section, transmits the motion to the stabilizer torque tube lever.
Aileron
The transmission of the aileron control is of the rigid rod type for the part of the
circuit inside the half wing, while of a steel cable for the fuselage part. A cable
control circuit is confined within the cabin and it is connected to a pair of push-pull
rod systems positioned in each main wing which control ailerons differentially.
Rudder
Directional control acts through a system characterized by a steel cable that
connects the pedal system to the vertical tail lever control. From the pedal system
two rods connect also the nose landing gear and guarantee the ground maneuvers.
Flap
The Flap command is of the rigid rod type. The torsion tube connecting element of
the two surfaces, is hinged of supports integral with the fuselage structure. The
rotation movement is transmitted by means of the lever whose positions are
regulated by the electric linear actuator controlled by a lever switch placed on the
instrument panel. Flaps act in discret mode; the indicator lights show three
markings related to clean (UP), takeoff (T/O) and landing (LND) positions*. A
breaker positioned on the right side of the instrument panel protects the electric
circuit.
*) for aircraft embodying MOD 2002/243 flap position is displayed on a dedicated indicator
included in the Garmin G3X Touch near the trim indicator.
Trim
Stabilator trim control is operated by means of integrated button on both pilot and
copilot sticks. The buttons activate the linear actuator connected to the shelves by
means of a plate. The electric trim system is activated/disconnected by means of a
dedicated switch on the upper side of instrument panel. Trim position is displayed
on a dedicated indicator included in the Garmin G3X Touch.
