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.
yes, there is. there have been many pistons with hot wings, fjukkwit.
