For a CRJ 700 with 70 PAX United, how many POB are on board?

• A. 2
• B. 3
• C. 4
• D. 5

Answer: (B)

Portable oxygen bottles are part of the aircraft’s emergency oxygen provisions and their number is set by the aircraft’s equipment list, not by how many passengers are on board. On a CRJ 700 configured for United with 70 seats, there are three portable oxygen bottles installed. This setup provides oxygen for the flight crew (and any needed extra support) during depressurization or medical situations, while the passenger oxygen is supplied by the fixed passenger oxygen system with automatic masks. So, even with 70 passengers, the aircraft still has three POB on board.
