Which system is primarily responsible for providing anti-ice protection?

The Integrated Air System Controller (IASC) is primarily responsible for providing anti-ice protection as it manages the overall system designed to prevent ice formation on critical components during flight. The IASC coordinates various sub-systems and ensures that the anti-ice protection functions efficiently and effectively when conditions for ice accumulation are detected.

This system typically regulates the heating elements that are applied to surfaces such as wings, engines, and other areas prone to icing, allowing the aircraft to maintain operational performance and safety in ice-prone conditions. The IASC’s ability to integrate inputs from other systems enhances its functionality, making it a critical component in maintaining safety during adverse weather conditions.

In contrast, the electrical system contributes to the operation of the anti-ice components but is not solely responsible for controlling it. The Anti-icing Control Unit, while significant, usually plays a role within the broader management of ice protection rather than being the primary system. The Ice Detection Unit is crucial for identifying when ice is present but does not provide protection itself; rather, it alerts the systems to activate icing measures.
