What is the maximum POB count applicable on a CRJ 700 according to the provided rules?

• A. 2
• B. 3
• C. 4
• D. 5

Answer: (B)

Portable Oxygen Bottles (POBs) are limited by the aircraft’s oxygen distribution system and the operator’s rules. For a CRJ 700, the provided rules set the maximum number of POBs at three. This limit matches the aircraft’s certified oxygen capacity and storage constraints, ensuring there’s enough oxygen for the required crew and potential medical needs without exceeding what the airplane is designed to carry. Adding more POBs would push beyond the certified configuration and required safety margins. So, the maximum permissible POB count on a CRJ 700 under these rules is three.
