Fellow Aviators, Click on the link below to watch a 23 minute video from the NASA Lewis Research Center in Cleveland regarding horizontal stabilizer stalls due to icing, how to recognize the effects, and how to recover. While this may or may not have been involved in the recent crash in icing conditions, it is very valuable information indeed. In fact, since it mentions autopilot use and flap extension in icing conditions it is amazingly germane to the Buffalo accident. According to the recorders, it was concurrent with their first flap extension that they lost control. But this video was produced in 1998! This information is part and parcel of any instrument pilot's training and certainly calls the competence of this crew into question. The captain had been flying for Colgan Airlines for three years (I was not even a copilot after that amount of time at United) and the First Officer had just graduated from college in June, 2007! Compare their experience levels to that of Sullenberger and Skiles. And compare the outcomes of the two events! http://video.google.com/videoplay?docid=2238323060735779946

As far as autopilot use during icing, the pilot unfortunately was following the Faa recomendations which conflict with the NTSB. Two federal agencies that can't agree with one very important protocol. I would side with the NTSB but who knows what the pilot was trained with and what was the company policy on icing with that aircraft. If he was trained to follow the FAA policy then maybe if he was more experienced he would have gone against the grain, but who knows
