747-200/400 Anti-ice de-ice
What does the 747 use for de-ice/anti-ice, I'm sure it has a heated windshield and heated engine inlets and a heated wing. Besides the windshield being electric, how is the rest heated? Bleed air or electric? what other ice systems does it have. Thanks for your help. As you can guess I'm getting ready for round two at Cathay.
