No.

Are the wings protected from getting too hot, and if so how?
Yes, the anti-ice leak controller (AILC) monitors wing temperature, and regulates the anti-ice valves to maintain the appropriate temperature.

Which pilot’s WIPER switch is controlling?
The last one moved.

- Ground: OAT 10º C or less with visible moisture.
- Flight: TAT 10º through -40º SAT while flying through visible moisture.
Define visible moisture.
Visible moisture is a visibility of 1SM or less (fog on the ground or clouds in flight), rain, snow, sleet, or ice crystals.
When should the cowl anti-ice be turned on while on the ground?
