airtren, re your comment, "You're not saying that the HS has no contribution to the NU are you? But it reads that way."

No, I am not saying that the THS "has no contribution" to the NU attitude.

Now that I review it, you are right that the statement, in and of itself, wasn't nuanced as I have in the past and can read that way.
Thanks for reviewing your post, and making the above clarification..
But the contribution of the THS to the sustaining of the stall has been thoroughly discussed even if it has not been thus in the BEA Final Report, and my own views on the contribution of the THS are both expressed and known as are my views on why the stall continued instead of being recovered from.
..... I made the observation that overall, the behaviour and contribution to the stall of the THS has been thoroughly examined and the statement made on such contribution thus, (bolding is in the original) by someone who really knows what they're talking about, supports the view that the NU stick and not the THS were the critical factors:
I've expressed my opinion myself at least once on the THS contribution to 1) entering and 2) staying in STALL - this thread is repetitive.

Even though you may have NO acrobatic or fighter pilot training, and thus direct and repeated experience with entering and exiting stalls, I would ask nevertheless your opinion based on your pilot expertise:

Question:
If you were the AF 447 Captain, and had understood at the very moment of re-entering the cockpit, the Stall state, and the Cause for it, the extremely short amount of time left for a successful recovery, and had known what it takes to exit the Stall and recover the A/C, what would you have ordered the PF to do?

1. move stick ND ASAP and move THS manually to NEUTRAL or MAX ND ASAP
or
2. move stick ND ASAP and keep THS to MAX NU?
