Where would you verify the aircraft's maximum cabin altitude?

• A. In the takeoff weight section.
• B. In the cabin pressurization limits of the AFM.
• C. In the engine performance charts.
• D. In the MEL.

Answer: (B)

Maximum cabin altitude is a defined operating limit of the aircraft’s pressurization system, and the best place to verify it is the cabin pressurization limits section of the Airplane Flight Manual. The AFM is the authoritative source for all limits and procedures, including how high the cabin can safely be pressurized. This limit is tied to the system’s design and structural considerations, so staying within it ensures occupant safety and proper pressurization control. The takeoff weight section, engine performance charts, and MEL are unrelated to this particular parameter: weight limits, performance data, and maintenance/dispatch restrictions don’t specify the maximum cabin altitude.
