....ATR....I think you can conclude that overall, helo FBW has been underdeveloped and therefore under-utilised. As MP's post implies...it is very risky and costly to try and design a platform and do all the FBW development on that platform as part of a production programme. V22 and I fear S92 suffers from this approach, Although 609 has gained much from the struggles to get V22 to work. NH90 has had problems but they were in part alleviated by the earlier research work done. Comanche is the irony as it had utilised all the tailored handling qualities research and data gathering done by both NASA and the UK RAE...only to be cancelled! Certainly it is not a sensible approach to assume that a rotorcraft designed with conventional controls and AFCS can quite easily be retrofitted with full FBW...unless you have variable time and an infinite budget of course!
