New Scientist article on airframe icing

[The Nr Fairy]

An interesting article in this week's New Scientist about aircraft icing, using the ATR-72 at Roselawn in particular as an example.

I can't find it on the web, so you'll have to get the 1st Feb issue. I'm not a f/w pilot so I post the info for your delight and delectation.

Further discussion when you've had a chance to read it ?

Thanks for the tip, Nr Fairy! I subscribe to New Scientist but rarely get enough time each week to read it, so I'm currently about five months behind - I've got this week's issue at home so I'll "cheat" and read that article first!

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 (http://gltrs.grc.nasa.gov/) for those interested.
