What is the purpose of anti-icing systems?

The primary purpose of anti-icing systems is to prevent ice from forming on critical surfaces of the aircraft, such as wings, tail surfaces, and engine inlets. These systems are specifically designed to mitigate the risk associated with ice accumulation, which can degrade aerodynamic performance, disrupt airflow, and hinder the aircraft's overall control and stability.

When ice begins to form, it can create additional drag and reduce lift, potentially leading to dangerous flight conditions. Anti-icing systems typically utilize heated surfaces or chemical solutions to ensure that temperatures remain above the freezing point, thereby stopping ice from adhering to the aircraft's surfaces in the first place. This proactive approach is essential for maintaining performance and safety during flight in icy conditions.

In contrast, removing existing ice is typically the function of de-icing systems, which are activated after ice has formed. While the enhancement of lift and increasing engine power may be secondary outcomes in some scenarios, they do not directly relate to the primary function of the anti-icing systems.
