Can't help you there my friend,
That said I would like to use your post to pose another question...... (sorry)
Do you or anyone out there know exactly why (the exact easy to understand physics) an airframe will lose ice (without the use of boots etc) if the aircraft leaves icing conditions, but the outside air temperature still remains below zero. I know the process is called sublimation and I know how sublimation works in the way SLD turn to ice immediately.....what I don't know is how sublimation works in the opposite direction with OAT below zero.
I also know that kinetic heating effects of airspeed are not the answer (even though they may be a contributing factor at speeds above 200 kts) as slow light aircraft also lose ice in sub zero temperatures.
I suspect that it will have something to do with air friction in some way......
Can anyone help. The process is elluded to in so many places but never explained.
Cheers.
