caption_attribution_description: English: Close-up of a section of a pneumatic de-ice boot on the leading edge of an aircraft's wing. The boot is made of reinforced rubber and the lines on the boot are rows of stitches; the strips between the stitching inflate and become half-cylindrical, thus breaking ice off the wing leading edge. When not in use the strips are held flat by vacuum air; the airflow is changed to pressurise and inflate the boot when required. Inflation is typically for a few seconds every few minutes when the system is being automatically controlled; manual control is typically also available.
context_page_description: Ice protection systems are designed to keep atmospheric ice from accumulating on aircraft surfaces, such as wings, propellers, rotor blades, engine intakes, and environmental control intakes. If ice is allowed to build up to a significant thickness it can change the shape of airfoils and flight control surfaces, degrading the performance, control or handling characteristics of the aircraft. An ice protection system either prevents formation of ice, or enables the aircraft to shed the ice before it can grow to a dangerous thickness.
