For this reason, most fly-by-wire systems incorporate either redundant computers (triplex, quadruplex etc.), some kind of mechanical or hydraulic backup or a combination of both.
It will be constructed primarily from composites and metal and is to be the first commercial helicopter to incorporate fly-by-wire flight controls, with tactile cues.
It has a quadruplex digital fly-by-wire control system providing artificial stability, manual operation alone could not compensate for the inherent instability.
Modern airliners that have fly-by-wire technology avoid the critical angle of attack by means of software in the computer systems that govern the flight control surfaces.
