Yes.

That was my first impression after hearing about all these stick shaker occurances. You really gotta be behind that plane to get it that slow. It's really not a hard airplane to fly if you are paying attention.

I aslo assume that if they are flying at REF on landing then it's pretty easy to approach stick shaker. Horizon teaches Q400 pilot to split the bug between REF and REF ICE.

FYI, REF ICE isnt an Ice speed. It's just how its labled in that plane. Kinda like V-AP in in some jets
