Which term describes the act of removing ice accumulation from an aircraft structure?

Explanation:
Removing ice accumulation from an aircraft is called deice. When ice has built up on wings, tails, or other surfaces, it impairs lift, increases drag and weight, and can affect control effectiveness, so actively removing that ice is essential for safe flight. Deice refers to processes that physically remove ice, such as inflatable boots that crack and shed ice, heated surfaces, or chemical de-icers. This is different from anti-icing, which is about preventing ice from forming during flight. The other terms don’t describe removal: dew is condensation, deposition is ice forming from vapor, and detonation is an explosion.
