Spleener, your quote
"A330/A340 - FBW = artificial stability = CG control"
is not clear to me. Are you saying that since the 330/340 has FBW that it also means that it has artificial stability?
yet you also later say there is downforce on the tail for all control laws.
and artificial stability somehow give CG control?
Are there no mechanical back up modes anymore, should the computers fail? After all, without this artificial stability, it would be up to the pilots to sense the instability, judge the flight conditions such as attitude, speed, and pitch rate, and continually adjust the control surfaces. Orville and Wilbur did it, after all.
