What is the cowl anti-ice limitation temperature?

The cowl anti-ice limitation temperature is significant in ensuring optimal performance in potentially ice-forming conditions. The correct answer indicates that the cowl anti-ice system becomes necessary when the outside air temperature is at or below 10 degrees Celsius, which is critical for preventing ice accumulation on the engine inlets. Activating the cowl anti-ice at this temperature helps maintain proper airflow to the engines, thereby enhancing safety and performance during flight. Understanding this limitation ensures that pilots can make informed decisions regarding the operation of anti-ice systems in varying temperature conditions, particularly in colder climates where ice can form on critical engine components.
