What is the minute-long oxygen capacity of passenger oxygen generators?

• A. 11 minutes
• B. 13 minutes
• C. 14 minutes
• D. 18 minutes

Answer: (B)

Passenger oxygen generators are built to provide a measured amount of oxygen to everyone in the cabin after deployment, lasting for a specific period so the crew can manage the emergency and the aircraft can descend to a safer altitude. The standard duration for passenger systems is about 13 minutes, which is why 13 minutes is the correct choice. Times shorter than that aren’t the typical spec, and longer durations aren’t the standard figure used in training and manuals. This duration is tailored to cover the immediate emergency for passengers, while crew oxygen systems are designed to last longer to ensure pilots and cabin crew have time to respond.
