Which term describes a wall that divides the cabin interior wholly or partially?

• A. Bulkhead
• B. Bank
• C. Comat
• D. Connection

Answer: (A)

A wall that divides the cabin interior wholly or partially is called a bulkhead. In aircraft, bulkheads are partitions that separate sections of the cabin—forward, mid, and aft—and can be full-height from floor to ceiling or only partial-height, still serving to divide spaces and sometimes providing mounting locations for doors, galleys, or equipment. They also often act as structural and pressure boundaries in a pressurized fuselage. Bank, by contrast, describes a turning motion of the airplane, not a wall; comat isn’t a standard term for cabin walls; and connection isn’t used to name a wall that partitions the cabin.
