AIRBUS A320/A330/A340 electrical flight controls - A family of fault-tolerant systems

摘要: The digital electrical flight control system of the Airbus A320/A330/A340 is discussed. A320 was first civil aircraft equipped with such a system. It certified and entered into service in quarter 1988. A330 A340 have identical systems, closely related to These systems are built very stringent dependability requirements both terms safety (the must not output erroneous signals) availability. basic building blocks fail-safe monitoring computers. channel performs function allocated computer (control surface for example). ensures that operates correctly. A high level redundancy Special attention has been paid possible external aggressions. tolerate hardware software design faults. described together significant differences between A330/A340, experience.
