What happens if the oxygen blowout disk is missing in the A320?

• A. The system becomes non-operational
• B. The crew bottle requires servicing
• C. The cabin pressure will drop
• D. Emergency systems are activated

Answer: (B)

The correct answer highlights that if the oxygen blowout disk is missing in the A320, the crew oxygen bottle requires servicing. The blowout disk is a safety feature designed to release pressure in the event of an overpressure situation. If it is missing, the system can still function but poses a risk of improper pressure management. Thus, the need for servicing arises to ensure the integrity and safety of the oxygen system. In the context of the other options, while the absence of the blowout disk does not directly result in the system being completely non-operational or automatically activating emergency systems, it does raise concerns about the reliability of the performance of the oxygen supply. Therefore, servicing is essential to confirm that all components are intact and functioning correctly to guarantee crew readiness in an emergency.
