Which component is responsible for controlling engine anti-ice functions?

The component responsible for controlling engine anti-ice functions is the FADEC, or Full Authority Digital Engine Control. FADEC is an advanced digital control system that manages all aspects of the engine's operation, including fuel flow, air-to-fuel ratio, ignition timing, and, importantly, anti-ice systems.

In the context of aircraft engines, anti-ice functions are critical for preventing ice build-up on engine components, which can adversely affect performance and safety. The FADEC system monitors environmental conditions and sensor data to determine the optimal settings for the engine, including when and how much anti-ice measures should be applied to maintain safe operational levels.

While other components like the ECU (Engine Control Unit) may perform functions related to monitoring and controlling certain engine parameters, FADEC encompasses these functions with comprehensive authority over the engine's performance and safety systems, including the anti-ice function. The ISP (Intercooler System Pressure) and BLEED systems, while they play roles in engine operation, do not specifically handle the control of engine anti-ice functions in the same integrated manner as FADEC.
