Fly By Wire
Well, I understand your concernes in regard to EMP, but without any experience made in that field all we can do is to speculate.
The AF447 Flight did not have any probs with FBW, as far as I know. The root case were wrong indications due to failing external sensors and apparently the crew failed in the interpretation of cockpit displays. I believe the result would have been exactly the same if that airbus would have had conventional mechanical controls and a conventional AFCS.
The biggest difference in FBW in Planks and Helicopters is that in Planks the FBW will not let you exceed defined limits, while in the helicopters there is no limitation or restriction programmed into the FBW. It is a common misbelieve that NH-90 will limit the pilots inputs when coming close to potentialy dangerous attitudes or flightconditions. In that regard it is like a mechanical control system, it will just feed the pilots input into the rotors, no matter whether that will result in the exceedance of limits or not.
With your remarks on the MMI you are spot on! A nicely sized cockpit, but but the architecture of the MFDs and especially the DKU hold a lot of room for improvements, but then none of the glass cockpits I have flown in the last 10 years (quite a lot) were anywhere close to perfect.
