What is the function of an anti-ice system on a small aircraft?

• A. To prevent or remove ice buildup on critical surfaces by heating or applying glycol/bleed-air methods.
• B. To enhance cabin pressurization.
• C. To dehumidify the air in the cabin.
• D. To improve engine thrust.

Answer: (A)

Anti-ice systems are designed to keep critical surfaces free from ice during flight. They accomplish this by actively heating the leading edges of surfaces like wings (and sometimes windshields) or by applying anti-ice fluids, using methods such as electrical heating or bleed-air–driven heat. By preventing ice buildup, these systems maintain lift, control, and visibility in icing conditions. This is different from de-ice systems, which are for removing ice that has already formed (with boots or chemical methods). The other options don’t relate to preventing or removing ice on flight surfaces.
