The autopilot system is an integrated autopilot and flight director. The autopilot system has the automatic flight-control system (AFCS).

The AFCS supplies the dual-independent flight directors, a two-axis autopilot, and automatic pitch trim. Also, the AFCS interfaces with the yaw damper system.

The AFCS operates with the integrated-avionics processor system (IAPS). The IAPS collects the data for the avionics systems. The flight guidance computers are installed in the IAPS card cage (ICC). The AFCS gives the course, heading, and preselected altitude data to the electronic flight instrument system (EFIS).

The engine indication and crew alerting system (EICAS) gives the control-surface position data to the AFCS. The attitude and heading reference system gives the attitude and heading data through the IAPS input/output concentrators (IOC) and directly to the AFCS.

The AFCS calculates the vertical and lateral flight-guidance commands to cause the aircraft to become stable and to keep the aircraft on the correct pitch/roll attitude. The flight directors show the flight-guidance commands on the primary flight displays.
