Excuse this novice posting, but with literally thousands of posts to trawl, and this thread throwing up more possibilites such as rudder seperation in flight, aircrew being asleep, I thought (at least for my own sake) it may make sense to pop some sort of 'simple' overview in - with that in mind can anyone answer the following:
Do we know if the ACARS was giving information which can absolutely point to specific causes (IE not some fault causing another) in other words are they diagnostic enough to pin anything down? - yes or no
Is it possible to ascertain the 'event duration' - is there ANY certainty over it being a progressive or sudden event? Yes or No?
As for the Aircraft itself: without wanting to discuss possibilites - is it a fact that the aircraft could have been in an 'insipid' or 'creeping situation' whereby the crew would be unaware of any deviation of flight level until too late? Yes or no?
Is a situation possible where no control input 'works'? Yes or no?
and two final ones:
If any flight deck crew were asleep could anyone remain so assuming the seemingly severe turbulence?
Assuming anything less than catastrophic damage a altitude or an irrecoverable flight path, etc, IF a semi gradual descent was underway would there be ANY potential for system recovery/ and or any icing to ease off? Yes or no?
