When I first went onto the 'bus technology, discovered what you are discussing on my very first sim ride...it'll stick with me forever.
-First sim session, at altitude, me PNF and the sim had a spastic and suddenly we rolled and went into a nose down attitude, loss of control.
-We continued trying to fly it not knowing at that point is was a sim fault.
-steep nose down attitude, nose not coming up. I was calling "pitch up pitch up" and realised the only way to assertain if my colleague was making the correct inputs was to look up and over to his stick/hand to see what he was doing!! I was not very impressed with airbus philosophy at that point! quite sobering.
Amittedly, if it were happening for real, and there was any doubt as to the correct/sufficient input being made, one would hit the little red takeover button and do his thing. ALL a bit messy however, when compared to seeing the yoke move in your periphery and being instantly satisfied that your mate is on the job.
That being said, the stick concept and FBW control laws have some very nice features.
