What happens if a Cowl Anti-icing Duct ruptures?

The correct answer in this scenario is that the escaping pressurized bleed air is contained inside the outer duct. When a cowl anti-icing duct ruptures, the design of the ducting system ensures that the air doesn't escape freely into the surrounding environment. Instead, the pressurized air is contained and directed within the outer duct to minimize potential hazards and maintain system integrity as much as possible.

This design is crucial because it prevents uncontrolled venting of pressurized air, which could lead to structural integrity issues or affect the aircraft's performance. It is important for pilots and maintenance personnel to understand how the system is engineered for safety and functionality, especially in varying flight conditions where ice formation could pose significant risks. Other options suggest scenarios that do not accurately reflect the safety measures in place for the cowl anti-icing system.
