Which component is primarily responsible for the activation of anti-icing for the wings?

The component primarily responsible for the activation of anti-icing for the wings on the Dassault Falcon 7X is engine bleed air. This is because the anti-icing system relies on heated air from the engines to prevent ice accumulation on the wing surfaces during flight. The engine's bleed air system extracts a portion of the high-temperature, high-pressure air from the engines, which is then routed to the leading edges of the wings, providing the necessary heat to maintain their surface temperature above the freezing point.

While wing temperature sensors play a crucial role in monitoring the temperature of the wing surfaces to ensure effective ice protection, they do not activate the anti-icing system themselves; rather, they provide essential feedback to the flight control systems. The flight control computer processes information from the sensors and may assist in managing the overall operation of the anti-icing system, but it does not directly supply the heat required for the anti-icing function. The landing gear unit is not related to the anti-icing system on the wings at all, as its function pertains to the aircraft's landing and takeoff operations.
