The acronym POB stands for which of the following?

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

Answer: (B)

The thing being tested is the common terminology for a compact oxygen supply you carry with you on a flight. POB stands for Portable Oxygen Bottle, which is the cylinder that holds compressed oxygen and can be carried to provide supplemental oxygen to a passenger or crew member with a mask or cannula. Why this is the best fit: "Bottle" is the standard term for the portable cylinder that actually contains the oxygen you use in flight. The word implies a gas container you can carry and connect to a masking device. The other options describe different items (a bag, a canister, or a wording that isn't the conventional label for the portable oxygen unit), which don’t refer to the actual oxygen cylinder used aboard aircraft.
