JD-EE,
CogSim, the last line of your recognizing icing posting prompted an "Oh goodie!" from me - in a very sarcastic tone.
"Under some icing conditions, even a 3-minute exposure can substantially affect the handling of the aircraft."
That was kind of the point. We think that there is more than a good chance that the pitots iced. In our discussions we are isolating the problem. We are implicitly assuming an otherwise clean a/c. Who know's what else iced. As the NASA tutorial snippet shows, a lot of structures may have accreted ice. We just don't have enough information to know what that means for the chain of events, if anything.
