What are boots on an aircraft?

The boots—which are not boot shaped, nor are they on the wheel pants—are rubber strips attached to the leading edges of the wings and tail surfaces. Once activated, they are pressurized with air and they expand to break the ice off the boot surfaces.

Can planes deice themselves?

Planes will have anti-ice equipment on the wings and engines, Manders said. These systems use electrics or hot air from the engines to heat up the leading-edge surfaces. “This [lets] the ice melt and fall off, or prevents its formation altogether,” he said.

What is the purpose of vacuum in a de icing boot?

During expansion, the boots are inflated by pneumatic pressure that breaks away the ice. They are then deflated by vacuum suction. When not in use, the system will continuously apply a vacuum to hold the boots tightly against the aircraft while not in use.
