Tail stall in icing

I've been flying for almost 40 years, everything from little stuff to big iron and I've never seen this video.
Not too relavent to what we do with the 170 but might help someone on the list.

Definitely something you want to look at if you fly in ice, especially with nonboosted controls. If you know
someone that flys medium aircraft in weather you might want them to watch it too. It's a little long, but has some stuff I didn't know. For instance why adding some extra speed to your approach can actually be dangerous if the tail is contaminated, especially when adding flaps.

SloPoke,
This video is very worthwhile, I hope everyone here that sees this thread takes the time to view it. I am giving the link to all of my flying buddies.

Is this what might have happened at Buffalo, NY.

It's possible. First they said it dove in- which sounded like a tail stall, now they say it hit flat.
I always thought it was prudent to bump up your approach speed if you thought you still had ice on the aircraft. It's worked for me over the years. Now I find out if you've got enough ice on the Horz. Stab. and you put down the flaps at a higher speed than normal you can have the the elevator go full down on it's own and be almost impossible to get it back.
Lots of information out there and hard to know it all. Just be careful out there.
