What is the distinction between an A/I DUCT failure and a WING OVERHEAT fault?

The distinction between an A/I DUCT failure and a WING OVERHEAT fault rests in the specific nature of the issues each indicates. An A/I DUCT failure typically suggests a leak within the ducting system responsible for air distribution. This leak would lead to decreased performance or temperature regulation within that system, potentially affecting cabin pressure and heating.

On the other hand, a WING OVERHEAT fault specifically points to a situation where the wing structure is overheating due to a fault, which may involve a malfunction in the heating elements used for de-icing or anti-icing purposes. It signifies that there is an operational issue resulting in excessive temperatures, thereby raising safety concerns but does not directly point to a leak like an A/I DUCT failure.

Understanding this distinction is critical for maintenance and operational decisions, ensuring that appropriate actions are taken based on the specific conditions indicated by these alerts.
