The system provides dual independent flight directors and a three-axis autopilot with automatic pitch trim control signals. The FCS-4000 also reduces pilot workload by providing automatic flight control of the airplane for nearly all commonly encountered flight situations and also delivers an exceptionally smooth ride for the passengers and crew.
