If a CRJ 700 has 3 POB, which configuration could explain it?

• A. 70 PAX
• B. 70 PAX United
• C. Both 70 PAX and 70 PAX United have 3
• D. None of the above

Answer: (C)

The key idea is that the number of people on board (POB) is determined by the crew complement, not just how many seats are in the cabin. A CRJ 700 can operate with two pilots plus at least one flight attendant, so you can have a total of three people on board even when the cabin is configured for 70 passengers. If either the “70 PAX” or the “70 PAX United” configuration is staffed with only one flight attendant, the total POB would be three. That’s why both configurations could explain a POB of 3. The other possibilities would require different crew counts (for example, more than one flight attendant would push POB higher, or no cabin crew would drop POB to two), which is why the option stating that both configurations could yield 3 POB is the best fit.
