How long would oxygen flow on Delta aircraft once the passenger oxygen masks are deployed?

• A. 10-15 minutes
• B. 12-22 minutes
• C. 20-25 minutes
• D. 30-35 minutes

Answer: (B)

The deployment duration of oxygen flow from passenger masks on Delta aircraft is typically between 12 to 22 minutes. This time frame is designed to provide sufficient oxygen for passengers in the event of a sudden cabin depressurization, allowing time for descent to a safer altitude where breathable air is available. The range of 12 to 22 minutes ensures that even in varying flight conditions or potential emergencies, oxygen supply remains available for a substantial period. This measure prioritizes passenger safety and comfort, addressing the critical need for airflow during emergency situations.
