The acronym POB corresponds to which phrase?

The acronym POB corresponds to which phrase?

• A. Portable Oxygen Bottle
• B. Portable Oxygen Bag
• C. Portable Onboard Bottle
• D. Portable Oxygen Canister

Answer: (A)

Portable Oxygen Bottle is the standard term for the acronym. In aviation, POB refers to a portable cylinder that stores oxygen for immediate, transportable use by passengers or crew during a depressurization or medical need. The word bottle conveys the rigid, pressurized container that actually holds the oxygen, which is why this option is the correct fit. The idea of a bag isn’t aligned with how oxygen is stored and delivered on aircraft, and while “onboard” is descriptive, it isn’t the established phrase used in the acronym. A term like canister would imply a different device or delivery method rather than the portable bottle used for this purpose.
