The N2 gauge arc turning white indicates power required for adequate ice protection up to what percentage?

The N2 gauge arc turning white indicates power required for adequate ice protection up to what percentage?

• A. 77%
• B. 60%
• C. 50%
• D. 90%

Answer: (A)

The white arc on the N2 gauge is a warning about the electrical load the ice protection system is drawing. When it turns white, it means the power required for adequate ice protection is within the system’s capability, up to about 77 percent of the available electrical power. If the load increases beyond that, the arc would move beyond white, signaling that you may not have sufficient power for full ice protection. Among the numbers given, 77 percent is the threshold that corresponds to the white indication.
