What statement is true regarding de-ice/anti-ice fluids?

The statement about anti-icing fluids being applied until they flow off surfaces is accurate because it emphasizes the importance of sufficient application to ensure optimal performance. Anti-icing fluids are designed to prevent ice from forming on aircraft surfaces. For them to be effective, they need to create a protective layer that can withstand the operational conditions. Excess fluid that flows off is often a sign that a proper layer has been established, allowing for maximum protection against ice accumulation during flight.

Furthermore, the information about applying anti-icing fluids uniformly is critical to ensure that all surfaces are treated effectively. Uneven application can lead to areas that are more susceptible to ice formation, which can compromise safety. The overall understanding emphasizes the importance of meticulous application processes when dealing with de-icing and anti-icing fluids to maintain aircraft safety and performance.
