What is the primary purpose of the Portable Oxygen Bottle (POB)?

• A. Provide portable oxygen to crew and passengers when needed
• B. Serve as a fixed oxygen supply for the cockpit
• C. Act as a cleaning device
• D. Provide ground service only

Answer: (A)

The main function of the Portable Oxygen Bottle is to provide portable oxygen to crew and passengers when needed. It allows oxygen to be delivered directly to a person who is far from the aircraft’s fixed oxygen outlets or during situations where portable, immediate support is required—such as a medical need, smoke in the cabin, or a decompression event. This portability means oxygen can be administered quickly and locally, by a crew member or to a specific passenger, until the situation is stabilized or the aircraft’s fixed oxygen system can take over. It isn’t a cleaning device, it isn’t a fixed cockpit oxygen supply, and it isn’t only for ground service use.
