Hi Clandestino.
"There was drastic increase in drag and reduction in lift at extreme angle of attack. You may call it Mickey Mouse if it suits you but in every serious aerodynamic treatise it is called stall."
I said it did not resemble.a "normal Stall" (entry to). Of all possibilities relative to entry, 447 had a large ballistic component, she was losing (had lost) energy rapidly due to the trajectory, not due drag. This is where I was going when I posited she would have Stalled sooner, at higher speed, without the influence of the 'locked in UP'position THS. Without Full UP THS, if entering an aerodynamic STALL, the two expected cues to entry may have been experienced with enough crew recognition to provoke an actual STALL recovery from them. That is conjecture, but I think my argument is established as a possibility.
A ballistic STALL is gentle, almost graceful, and there is no "Drastic increase in drag", and no compelling urgency for the Nose to drop. Buffet is likewise attenuated, and as in this case, less likely to cause alarm, or alert. The AoA was extreme, and this causes the functional Cg to locate aft, further reducing the normal signals of STALL as well as make recovery more problematic. Think "Tail Slide", or "Hammerhead".
Just as there is no drastic increase in drag, there is likewise no dramatic loss of lift, the lift is almost gone. Again, there is a gentle transition to ballistic and g accelerated descent only.
I write this with great respect, you have added a great deal to the knowledge base, and I fear my emotions have at times affected my writing. Apologies if I have been rude.
I am interested in reading your opinion.
