How long does PPOB provide oxygen on demand?

• A. 120 mins
• B. 90 mins
• C. 180 mins
• D. 60 mins

Answer: (C)

The correct answer indicates that the PPOB (Portable Oxygen Bottle) provides oxygen on demand for a duration of 180 minutes. This duration is significant in aviation, especially during emergencies, as it allows for continuous oxygen supply to support passengers or crew members who are experiencing hypoxia or other oxygen-deprivation situations. The ability to provide oxygen for this extended time frame ensures that individuals can receive adequate respiratory support, allowing for a safer environment on board the aircraft during critical moments. This time allotment allows flight attendants to manage any health emergency effectively until alternative measures can be taken or until the situation stabilizes. In contrast, the other options suggest shorter timeframes that may not provide sufficient support in emergencies involving oxygen needs, which emphasizes the importance of having a reliable source of oxygen available for those potentially in distress.
