The FADEC controls all of the following except:

The FADEC, or Full Authority Digital Engine Control, is an advanced electronic control system that manages engine performance and functions. Its primary roles include optimizing engine efficiency, ensuring compliance with operational limits, and managing starting sequences.

When it comes to the engine anti-ice function, while the FADEC plays a role in monitoring and providing inputs for the system, the control of engine anti-ice is generally handled by separate systems dedicated to ice protection rather than being fully governed by the FADEC.

The control of engine limits, starting sequences, and thrust reverser limits falls within the FADEC's responsibilities. This includes enforcing maximum and minimum thrust levels, managing both automatic and manual start sequences, and ensuring that thrust reversers are deployed and retracted within safe operational parameters.

Thus, the reason engine anti-ice is the exception is that it operates through a different set of controls and systems designed specifically for ice protection, rather than through the FADEC's primary functions.
