Definition: In the context of aviation, a "cabined" (also known as cabin-cabin) is a type of aircraft that has an enclosed cabin or cockpit section within its fuselage. This cabin typically includes windows for natural light and air circulation, and it is often designed to be more spacious and comfortable than a traditional cabin in which passengers are confined to a small enclosed space. Cabined aircraft are commonly found on longer-range or high-performance jets such as the Boeing 787 Dreamliner and
