It's a matter of terminology, further confused by the early "locked-in stall" accidents of some of the early T-tails being referred to as "deep stalls".
I would have called AF447 a "deep stall" in the general sense, in that it was a persistent, fully developped stall, with a few nasty contributing factors (no airspeed, THS, confused meatware), which lasted until FL000....
Maybe you could suggest some 'formal' terminology?
The 'deep stall' theory came up because it seemed much more plausible that a professional crew couldn't get out of a stall rather than wouldn't even try to. Especially the media picked it up readily, because it sounds appropriately dangerous.
Now many use it as a synonym for "really bad stall", which unnecessarily confuses people. See Ian's question, "were they told of the possibility of deep stall?"
Uhm, no, it wasn't in the "locked-in" kind and yes, it's got wings so obviously it can stall...
It's a garden-variety stall, do we need a special name for it?
