Alternatives
Other deicing techniques for larger commercial aircraft usually include, but are not limited to, electrothermal systems and bleed air systems. Electrothermal systems usually require substantial electrical power and are generally limited to large aircraft which can supply this energy through generators. Bleed air systems use hot air from the engine exhaust manifolds which is routed via high-pressure ducting (piccolo ducts) to the leading edge (main) of the wings, and/or horizontal and vertical tail stabilizers.
With Boeing's use of electrothermal ice protection on the wings of the 787 and with Boeing's More Electric Aircraft (or even All Electric Aircraft) initiative, electrothermal ice protection systems are being considered more prominently than boots and bleed air systems on commercial aircraft. General aviation jets also are studying the effect on thrust and fuel consumption of bleed air and additional benefits of its removal.

Famous quotes containing the word alternatives:
“The literal alternatives to [abortion] are suicide, motherhood, and, some would add, madness. Consequently, there is some confusion, discomfort, and cynicism greeting efforts to “find” or “emphasize” or “identify” alternatives to abortion.”
—Connie J. Downey (b. 1934)
“Clearly, society has a tremendous stake in insisting on a woman’s natural fitness for the career of mother: the alternatives are all too expensive.”
—Ann Oakley (b. 1944)
“The last alternatives they face
Of face, without the life to save,
Being from all salvation weaned
A stag charged both at heel and head:
Who would come back is turned a fiend
Instructed by the fiery dead.”
—Allen Tate (1899–1979)
