Whether this was a main wing stall or ice induced tailplane stall the resulting focus we've had on tailplane ice will at the least remind of us to think twice about ice forming on the tail and what that means to you, whether you fly anti-ice or de-ice aircraft.

Just because you have anti-ice doesn't mean that with a malfunction or OEI you won't be faced with ice buildup while trying to land.

And to my knowledge stoki, the nose would pitch down in a "pure" tailplane stall and that shouldn't set off the shaker or pusher. I could be wrong. I watched those videos from NASA and I'll play with it when I get to the sim shortly.
