Feathered,
Consider that the Boeing 787 (will) use electric heating in the wings for both de-ice and anti-ice, not bleed air. Boeing expects this technique to be both superior and energy saving.
At the risk of thread drift, I understood that the B787 will use bleed air ONLY for de / anti icing. BTW the real reason for no longer using bleed air for air conditioning is NOT fuel economy.
Does anybody know the facts on this? Apologies for any drift caused.
