4 / 15
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.

When can engine anti-ice be operated manually?
Engine anti-ice can be operated manually both on the ground and in flight. This means that the system can be activated to prevent ice from forming on the engine during both stationary and moving conditions. The option "On the ground or in flight" indicates that the anti-ice system can be used in either situation, providing flexibility and ensuring the safety and efficiency of the engine operation. The condition of the TAT (Total Air Temperature) being above 10 degrees is not relevant to the operation of the engine anti-ice system.

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.

The engine anti-ice systems operate through the delivery of bleed air to the inlet cowl. The hot air for engine anti-ice is provided:
10 / 15
If the total air temperature (TAT) is above 10 deg.C, both Manual and Automatic wing anti-ice operation is inhibited for:
The TAT inhibit is removed any time TAT drops below 10 deg.C.
11 / 15
Only the forward windows have exterior surface anti-icing. The forward windows have exterior and interior surface anti-fogging protection. The side windows have interior surface anti-fogging protection only.
