The autopilot (AP) system automatically controls the airplane in pitch and roll attitude via servo control of ailerons, elevator and aircraft trim system. The two autopilot computer channels operate in a high priority/low priority (active/standby) configuration.
Assignment of priority channel is alternated on power-up. The high priority channel provides control functions, while the low priority channel operates in a back-up mode. The autopilot/yaw damper actuators and pitch trim interface can only be driven by the priority channel.
In the event of a channel failure, the priority will automatically switch to the other channel.
Each FGC shall determine which symbol generator is driving the selected PFD, as selected on the reversion control panel located on the pedestal. The following guidance data is received from the appropriate symbol generator, via the Avionics Standard Communications Bus (ASCB), for use in the FGC:
Air data source identification Lateral and vertical path deviations Attitude source identification Distance to station NAV source identification Tuned-to-NAV and To/From status Course error Inner, Middle and Outer marker data Heading error Radio Altitude
The source of other guidance information is selected via the source identifier received from selected PFD symbol generator. The data received includes:
. IRS:
Roll Angle Normal acceleration Pitch Angle Ground speed Roll rate True track angle Pitch rate Flight path angle Yaw rate Magnetic heading Longitudinal acceleration True heading Lateral acceleration Inertial vertical speed
. ADC:
Baro-corrected altitude True airspeed (TAS) Pressure altitude Dynamic pressure Vertical speed VMO Mach

Calibrated airspeed (CAS)
. FMS:

Manual selection of the master AFCS channel is accomplished via the pop-up menu on either multi-functional display (MFD), in conjunction with the MFD control panel located on the pedestal.
