How many crew oxygen systems are installed on the A320neo?

• A. Two
• B. One
• C. Three
• D. Four

Answer: (A)

Two independent crew oxygen systems are provided, one for each pilot. This setup ensures that if one system has a fault or needs maintenance, the other pilot still has immediate, guaranteed oxygen supply. Each system feeds the pilot’s own oxygen mask with its own regulator, supporting rapid donning and continuous supply in a depressurization or smoke scenario. The passenger cabin oxygen system is separate from the crew system, so it doesn’t affect the cockpit’s oxygen redundancy. That combination—two dedicated crew systems—gives the necessary reliability and safety for both pilots.
