Helicopters and Fly-by-wire?
Are there any helicopters using a fly-by-wire system? I'm not thinking SAS/ASE, but a fully blown FBW, like for instance in A-320, or F-16, where pilot's inputs feed the flight control computers, which in turn execute control movements to meet the pilot's demands (like roll/pitch rate, load factor etc.) and there's no mechanical reversion. I am asking, because I think that helicopters, with all the control complexity, cross-coupling, instabilities and generally less-than-perfect handling qualities (at least compared to FW a/c) seem to be perfect candidates for such a system, which could greatly simplify the handling, ease pilot's workload and enhance safety...
So, are such systems currently available, or under developement, or maybe there are some issues precluding the use of FBW in helicopters?
