"Except that Direct Law throws the crew into a situation where the aircraft handles differently in *every axis* compared to what they are used to, which would likely be more risky than the current design."

You are suggesting the crew are better off with a "hybrid" control Law, Direct in Roll, and Load factor in Longitudinal.

That makes no sense, PF handled the Direct axis, but had consummate trouble with his "familiar".

The facts belie your proposal....

"How are you programming in a 3deg THS limit in your sim when there is not one on the a/c - are you using a THS-failure setup of some sort or are you physically holding the trim wheel to override the autotrim or what?"

The THS did not move for 43 seconds between the two STALL warnings, 1 and 2.
Shouldn't that be programmed into the sim, when replicating the climb?
It stopped at three degrees, then resumed at the top, to smoothly go to MaxNU, where it stayed til impact. This is AUTOTRIM? Ascending, was PF's elevator limited? After the beginning of Autotrim at STALLWARN 2, did he regain elevators fully?
