Elevator position is displayed on the FLIGHT CONTROLS synoptic page. A full-scale deflection of the elevator’s position indicator corresponds to maximum travel.
Pilot inputs to the elevator are through dual control columns. The control columns are normally connected through a torque tube, so they rotate in unison.
A control rod transmits pilot commands to the left and right forward quadrants. The left side quadrant assembly includes a cable interface with the stick pusher servo of the stall protection system.
Separate left and right cable circuits carry the elevator command through the fuselage and terminate at the respective aft quadrants located in the rear section of the fuselage. The aft quadrants each drive an output rod that is connected to two control rods in series. The first control rod is connected to a gain changer mechanism, which is a four bar linkage that pro-vides a non-linear gearing between control column movement and elevator surface. The second rod is connected to a pitch feel simulator that provides artificial feel forces. Aft of the gain changer mechanism, a series of control rods, levers, and a torque tube transmit the elevator command to two elevator power control units per elevator.

PITCH DISCONNECT
When pulled, the PITCH DISC handle isolates a jammed elevator control system. Pulling the handle, then turning 90° will allow the pilot or copilot to control the non-jammed elevator. A PITCH DISCONNECT (W) CAS message will also be illuminated on the MFD.

SECONDARY FLIGHT CONTROLS
DESCRIPTION
Secondary flight controls include flaps, multifunction spoilers, ground spoilers, aileron, rudder, and horizontal stabilizer trims. Flaps are electrically controlled and hydraulically actuated. Horizontal stabilizer, aileron, and rudder trims are elec-trically operated. The multifunction spoilers and ground spoilers are operated hydraulically but controlled via electrical sig-nals generated by the SECU. Position indicators for the secondary control surfaces are located on the MFD and the FLIGHT CONTROLS synoptic page.

COMPONENTS AND OPERATION AILERON TRIM
Aileron trim is achieved by means of an aileron trim tab located on the left aileron. The trim tab is moved by an electro-mechanical actuator located in the left aileron. The trim actuator is activated by movement of the aileron trim switches on the pilot and copilot’s control wheels.
