Looked at it today. Good article. One thing that struck me as odd was the reasons they gave for icing to be more of an issue for turboprops than jets:
More time at lower levels
Less excess engine heat to use for deicing
More difficult to observe icing because of high wing placement (Hmm
)
Surely they missed the most important, that jet speeds are significantly higher, and the faster you go the warmer the TAT (and hence the skin)? I'd imagine that finding supercooled liquid droplets at temperatures cold enough for them to stick at more than 300 knots is pretty hard.
Lots of good icing stuff from
NASA Glenn for those interested.
