When will wing anti-ice operate automatically?
The wing anti-ice system operates automatically only in flight. This means that the system is designed to activate and de-activate itself without any manual intervention when the aircraft is in the air. It does not operate automatically on the ground, indicating that the system needs to be manually controlled during ground operations. The answer also indicates that the system does not depend on the Total Air Temperature (TAT) being above 10 degrees Celsius for automatic operation.
6 / 15
An additional wing anti-ice inhibit for Automatic Wing Anti-ice operation (independent of the TAT inhibit), is active during the takeoff phase of flight.
Automatic wing anti-ice operation is inhibited for 10 minutes after takeoff. Manual wing anti-ice operation is not affected by this inhibit.
7 / 15
The selectors must be ON for the engine anti-ice system to operate on the ground, since AUTO does not operate on the ground.

What is the position of an engine anti-ice valve when the ENGINE ANTI-ICE selector is in AUTO and EAI is displayed?
When the ENGINE ANTI-ICE selector is in AUTO and EAI is displayed, it indicates that the engine anti-ice valve is open. This means that the valve is allowing hot air from the engine to flow into the engine intake, preventing ice from forming.
