The passenger oxygen generators are designed to provide oxygen for how many minutes?

• A. 10 minutes
• B. 13 minutes
• C. 16 minutes
• D. 22 minutes

Answer: (B)

The main idea here is understanding how long passenger oxygen generators are expected to provide breathable oxygen after a depressurization event. The system’s duration is determined by how much chemical oxygen material is carried and the flow rate needed for a passenger to breathe comfortably during the emergency. For passenger oxygen generators, the design is to supply oxygen for a set period long enough for the airplane to descend to a breathable altitude and for passengers to stay oxygenated while masks are in use. That specified duration is 13 minutes, which matches the standard rating for these generators. The other durations would either fall short of what’s needed for a safe descent and mask use, or imply more material and weight than the typical passenger system is designed to carry.
