During an emergency kit specification, the passenger oxygen generator duration equals how many minutes?

• A. 5 minutes
• B. 13 minutes
• C. 15 minutes
• D. 28 minutes

Answer: (B)

The main idea is that the duration of the passenger oxygen generator is how long oxygen is supplied after deployment, enough to get everyone to a safe altitude during an in-flight emergency. The 13-minute duration matches the typical requirement of a little over the minimum (about 12 minutes) and adds a small safety margin for variations in usage and the time needed to descend to a breathable altitude. Five minutes would be too short to cover the descent, while longer durations like 15 or 28 minutes aren’t aligned with this specific specification in the test and would be more than necessary.
