I read the report.
I read most of this discussion.
I don't understand.
There were cases where the pilots confused overspeed buffeting with a stall (or the other way round) which led to stick shakers and pushers. Is there no pusher on the AB? (maybe because the protections in normal law should always prevent a stall?) Hard to believe.
I was expecting to see an increasing IAS as they climbed (static decreasing while pitot remains constant as it is iced shut). The report does not mention that, so there was no indication of overspeed.
Stall recovery is the most basic thing that everybody who flies an airplane gets taught. I can't believe that they had three pilots that were unable to recognize the situation and do anything about it.
Very strage.
