Lyman, I presume that by "ineffective control" you allude to the fact that after a stall control effectiveness isn't what it is while flying.

From what I have seen of the FDR traces, at those times where the SS was moved forward, the attitude (and elevator command) changed toward more "down" but what does not seem to have happened was s sustained and patient nose down input when it was needed. Rate damping and control responsiveness in big jets has been discussed at some length in various previous threads on this topid.

I am a bit confused at your comment on ineffective controls. The SS traces showed me that Bonin tried to get the nose up, and to keep the nose up, and the nose stayed up.
In that regard, the controls were indeed effective.

I realize there are two related elements to the rate of response of nose position inputs: elevator command and THS trim both being part of the package in smoothly changing pitch attitude, and holding it.
