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 ?

Hot bypass air from the engines is what they use, in general. I have to
admit I do not know it the 787 is going to go truly all electric, or still
use hot engine air to heat the wings.

Once you get up to airliners of a larger size, the use of boots is not
common. In smaller turbine commuters, and in piston planes, (especially
pistons) there is not enough heat produced to heat wings.
