Default How fast does the skin of the airplane cool to surrounding temperatures?

The wings couldn't melt snow _and_ freeze it. They could freeze water
droplets, or melt ice particles, but not both.


Have you tried this with your simulator?

We have six airplanes here, and when we take them out of a warm
hangar into falling snow, the snow melts on the airplane, and then the
resultant water freezes as the structure cools off. Makes a mess. Works
better to open the hangar door and let the airplanes cool off first
before moving them outside.
Maybe you should take your computer outside in various weather
conditions and see frost form or snow melt and refreeze. Be sure it's
turned off, like the real airplane.

I bet you've never seen ice fog generated by an airplane
propeller. An aircraft on runup can trugger fog over the whole airport
in a minute or two under the right conditions. Maybe the fan on your
computer could be made to duplicate it?
