Why is N2 going yellow when Wing+Cowl AI is on?

Hello!

I tried to find the answer in the system descriptions from Smartcockpit, but but either I didn't get it or I didn't find it...

As the title says, why is N2 showing yellow when I activate wing and cowl anti ice at the same time?

Thank you!

It’s telling you the required engine thrust to maintain sufficient bleed air to run anti-ice systems.

N2 below the yellow line may not be sufficient to maintain wing temperatures suitable for anti-icing. The correct procedure for this situation is to maintain N2 in the green and use speed brakes to maintain speed.
