How do deicer boots help remove ice accumulations?

  1. By melting the ice

  2. By absorbing moisture

  3. By increasing the surface temperature

  4. By breaking up ice formations

The correct answer is: By breaking up ice formations

Deicer boots help remove ice accumulations by breaking up ice formations. They are inflatable rubber boots attached to the leading edges of aircraft wings and tail surfaces. When inflated, the boots expand and crack the ice that has formed on the aircraft surface, allowing it to break off in chunks. This action prevents the ice from forming a smooth surface that disrupts the airflow over the wings, which can cause a loss of lift or increase drag. Option A is incorrect because deicer boots do not melt the ice, but rather break it up. Option B is incorrect as deicer boots do not absorb moisture. Option C is incorrect because deicer boots do not increase the surface temperature but instead physically disrupt the ice formations.
