Abstract: A header assembly is configured to be secured between an inboard structure and an outboard structure within an internal cabin of an aircraft. The header assembly includes a main body including a first panel connected to an opposed second panel by a base panel. The main body is configured to limit light from passing therethrough. At least three separate and distinct anchoring members are configured to securely connect the main body to at least three separate and distinct reciprocal structures of the inboard and outboard structures.

Abstract: An example assembly includes a composite sandwich panel that further includes a facing, a hole defined by a perimeter, and electrical circuitry on the facing. The assembly further includes an electrical component and an insert. The insert is positioned within the hole and includes a first attachment component. The assembly further includes a cap that includes a second attachment component that is releasably attachable to the first attachment component through the hole to electrically couple the electrical component to the electrical circuitry and mechanically couple the electrical component to the facing.

Abstract: A self-cleaning floor assembly is configured to form or be positioned on a floor of an enclosed space. The self-cleaning floor assembly includes a moveable floor including a moveable floor panel, an actuation system that is operatively coupled to the floor panel, and a cleaning system proximate to at least a portion of the moveable floor. The actuation system is configured to move at least a portion of the floor panel into and through the cleaning system during a cleaning cycle. The cleaning system is configured to clean the portion(s) of the floor panel during the cleaning cycle.

Abstract: A lavatory complex for an aircraft. The lavatory complex includes a male lavatory facility and a female lavatory facility. The male lavatory facility includes stall units and may include urinals. The female lavatory facility includes stall units. Each stall unit suitably includes a single commode. The male and female lavatory facilities include at least one sink separated from the stall units by stall unit doors. The lavatory complex may include sinks that are not located within either the male or female lavatory facilities. A lavatory may include illuminating indicators; an illuminated, folding, baby changing station; a vanity; a self-cleaning toilet; and/or an illuminated faucet.
