Stability? I'm not sure we have a clear idea about the no-MCAS handling of the MAX. Not the absolute truth. Recent posts about marked unwanted rotation really shouts a kind of instability, though for the most of the last months it seemed that MCAS 'merely' countered a legally unacceptable lightening of stick forces while approaching the stall, and in very clearly defined configurations/speeds, balanced against long-established rules.
If indeed the bare aircraft - in any configuration - raced into an aerodynamically powered rotation into the stall, I too would be deeply concerned. But, for the last months, it has been strongly implied that MCAS only stops the lightening of control loads?
So the big question has to be, without MCAS, does the aircraft 'flop' nose-up in the late stages of stall entry?
It might sound as a stupid question, but what would change columns forces other than a pitch up tendency?
