Hello,

I guess de-icing is going to be a popular subject.

Question, please: On commercial jet airliners like, e.g., a 767 or
757, is there any in-flight deicing system for the wing and tail
surfaces, other than a leading edge pneumatic boot ?

What about the "main," large upper surfaces ?

How in general is wing de-icing accomplished on these new, modern jets
?

on flight, generally, not at all. On most jets, only the wings and engines
have anti or de-icing and it's accomplished by bleeding hot air out of the
compressor section of the engines. The engine anti ice is used frequently,
but wing de icing is seldom used simply because ice seldom forms on the
wings in flight. There is no deicing for the tops of the wings in jets.
