The temperature above the wings and below the elevators could be
slightly below ambient due to the lower pressure. I don't have a
number on what the temperature drop is on these surfaces, but
technically it is possible to have icing on the lifting surfaces when
the ambient temperature is above freezing. Sort of like carb icing in
above-freezing temperatures.


There has been a lot of hypothisizing about this in the past but NOBODY has
EVER been able to reproduce it.

You don't get icing just because a portion of the airplane is below 0C. I
doubt if droplets even touch any part of the airfoil where the
temperature/preasure is below ambient without running back. If they run
back, the first encountered the heated portion of the wing (leading edge).
You need supercooled water to get airframe icing.

It is another of aviations myths
