Flight controls

The main (dual) flight controls are all cable operated. Electrically operated aerodynamic trim tabs are fitted to the right aileron, right elevator and the rudder. A secondary power circuit and control system is provided for the elevator trim, there is no manual trim mechanism available. A rudder bias system uses engine bleed air to assist in directional control during engine-out operation. 

A single autopilot is able to follow commands from one of 2 Flight Guidance Computer s (FGC) and is controlled through a single flight guidance panel (FGP) at the top centre of the main instrument panel. The FGP is equally accessible from either cockpit seat. The active FGC will take roll, pitch and yaw inputs from the selected PFD and accompanying AHRS, and compute flight guidance commands for the flight director and autopilot. Lateral flight guidance modes include roll, heading, navigation and approach modes, with a half-bank function available. ‘Back-course’ approach mode is also available for use where these approaches are authorised. Vertical guidance is computed by the active FGC and is available in pitch, flight level change (speed hold) and vertical speed modes. A vertical navigation mode is also available when the primary navigation data is derived from the FMS.
