What is the function of the AILC?

The function of the AILC, or Aileron Integrated Load Control, is primarily related to managing bleed air for anti-icing purposes. This system is crucial in maintaining optimal performance during flight by ensuring that surfaces are kept free of ice, which can adversely affect aerodynamics and control. The AILC works by precisely managing the flow of bleed air to different components, helping to prevent ice from forming in critical areas. This is particularly important in colder climates or during specific flight phases, where icing can be a significant hazard.

The other options, such as controlling cabin temperature, activating emergency lighting, or monitoring fuel levels, involve separate systems within the aircraft and do not relate to the specific responsibilities of the AILC. Each of these functions is managed by distinct components designed for those specific tasks, ensuring that the aircraft operates safely and efficiently.
