Any time customers are on board, at least how many floor level exits must be available through normal or emergency means?

• A. Two
• B. One
• C. None
• D. Three

Answer: (B)

Having at least one floor-level exit available during boarding or while customers are aboard ensures there is a reachable egress path in an emergency. This minimum guarantees that, even if other exits are blocked or unavailable, there is a usable route for passengers to evacuate from the cabin. In practice, aircraft do have multiple exits for redundancy, but the requirement highlighted here sets the baseline at one floor-level exit that can be opened and used for normal or emergency egress.
