Which statement accurately reflects crew oxygen during rapid descent on the A320?

• A. Oxygen is provided only if the crew requests it.
• B. The crew oxygen supply is supplied by passenger oxygen systems.
• C. The system automatically provides oxygen for crew during rapid descent.
• D. The crew must manually retrieve oxygen from a portable supply.

Answer: (D)

During rapid descent, every crew member must have immediate access to oxygen. On the A320, the crew oxygen is not automatically supplied by the fixed passenger oxygen system. Instead, the crew must manually retrieve oxygen from a portable supply in the cockpit and don the mask to begin the flow. This independent, manual source ensures the pilots have reliable oxygen even if other systems are not yet delivering it. The passenger oxygen system deploys automatically for passengers, but the crew’s oxygen supply requires this manual action.
