When passengers are on board, which is the minimum number of floor level exits that must be available through normal or emergency means?

• A. At least one floor level exit must be available through normal or emergency means.
• B. At least two floor level exits must be available.
• C. Floor level exits are not required.
• D. Exits must be closed unless boarding.

Answer: (A)

The key idea is that there must be a usable egress path from the cabin even if operations are normal or in an emergency. Having at least one floor level exit available ensures passengers can evacuate if the primary exit is blocked or unusable. Floor level exits are the doors or openings at floor level that passengers can use to get to the outside without climbing, such as main doors with slides or overwing exits. While aircraft typically have several exits for redundancy, the safety rule being tested is that there must be at least one floor level exit accessible and operable when passengers are aboard. The other statements either imply no requirement, require more than the minimum, or suggest exits must be closed, which conflicts with safe evacuation principles.
