jcjeant - I'm trying to avoid any assignment of fault at the moment. But, after oscillating around a fair amount I'm close to convinced the three cockpit crewmembers will come out clean in any rational world. It's looking like they followed their "programming" to the point of utter confusion. It's hard to blame them for not breaking out of the strictures of their training to solve the problem.
Aside from that I think there may be a system design problem and most likely there may be a training error. (This latter point has already been tacitly admitted with the revised recovery procedures.)
(wry chuckle) Reading the above some of the AirBus related leaks make a lot of sense. They don't have to do anything because it was already done. And the some of the software design issue has a training workaround. (The lack of a fully time air flow based AoA reading in the cockpit is confusing if AoA and thrust are the real recovery for transient icing issues.)
