Abstract : The A320 is the first civil airliner to make extensive use of digital flight controls. Despite previous experience in this technological field, development of this system in a short time schedule has been a challenging issue. Simulation under its various forms, including simulators with a very high level of integration of actual aircraft components, have played a key role in the successful achievement of the Flight Control development process. It has allowed a better overall system quality to be achieved by the extension and thoroughness of testing performed: some 18,000 hours of simulator testing were logged at the time of A320-200 certification. Simulation has also proved to be a perfect complement to flight testing which today still remains the definite way to validate a Flight Control System and associated Handling Qualities: by increasing the safety and effectiveness of flight testing, simulation has participated in the overall development cost and programme monitoring. In the field of simulation used for airline training purposes, the introduction of digital flight controls has moved the representativity-critical areas from aerodynamic model accuracy to Flight Control System representation exactness. Aerospatiale is convinced that use of actual aircraft Flight Control computers is needed to guarantee fully the degree of fidelity consistent with the standard of training quality offered today. Simulator acceptance procedures had also to be adapted to address the case of closed loop controlled aircraft correctly.
