I think so, he sort of does the oral exam in a conversational way, and
I think I threw that out there while we were talking about it. One of
us might've mentioned the changing of the airfoil's shape, but it's
getting sketchy now...

Hmmm. Then maybe he wasn't really listening? Or he really =does= think
that the weight of ice is the main factor?

I had a flight instructor (from Florida) giving me instrument lessons
(in the Northeast); after I had spent an hour unsuccessfully removing
ice from the wings, I decided I didn't want to fly in that aircraft. He
acted as if he was ready to go flying in it and was put out that we had
to get another one. This wasn't too long after the airline crash in DC
with a Florida pilot who didn't respect ice.
