To find out if fluid failure has occurred after anti-icing, what should be checked?

To determine if fluid failure has occurred after anti-icing, the leading and trailing edges of the aircraft should be checked. This is because these areas are critical in achieving proper aerodynamic performance and ensuring that the anti-icing fluid has effectively prevented ice accumulation. The leading edges are particularly susceptible to ice formation during flight, and the anti-icing fluid is designed to prevent this.

Examining the leading and trailing edges helps to identify whether the fluid has remained effective; if there is ice present in these areas, it indicates that the anti-icing fluid either did not adhere properly or has lost its effectiveness, resulting in fluid failure. Maintaining the integrity of the anti-ice system is crucial for safe flight operations, as inadequate anti-icing could impact lift and control.

While checking other components like flight control surfaces, engine cowling, or ailerons can be part of a comprehensive safety check, they do not directly indicate the performance of the anti-icing fluid the same way leading and trailing edges do. These areas do not typically accumulate ice in the same manner and therefore may not be reliable indicators of fluid failure.
