A system for retrofitting a wall of an aircraft monument includes a modular power charging unit and mounting hardware. The modular power charging unit includes a housing containing an electrical port component, a cable harness, and a switch. The housing has a plurality of screw holes and a back panel having an opening through which the cable harness extends. The mounting hardware includes a plurality of threaded inserts, each configured to be inserted into one of a plurality of mounting holes formed in the wall, and a plurality of screws, each configured to extend through a screw hole of the housing and into a threaded insert. The housing is configured to be secured to a first side of the wall so that the entirety of the housing projects outward from the first side and only the cable harness extends through a cable-harness hole formed through a thickness of the wall.

A galley refrigeration system is provided in which a galley cart is positioned in the cavity of a galley compartment comprising at least a cart-facing opening positioned in a vertically intermediate region of the back wall, the galley cart or the galley compartment having a duct-facing opening positioned adjacent to the cart-facing opening. A heat exchanger configured to generate cooling air is provided within the galley compartment, adjacent the vertically intermediate region of the back wall of the galley compartment defining the cavity. An air supply duct, provided at the cart-facing opening, is configured to guide the cooling air from the heat exchanger into the galley cart, and configured to be detachably coupled to the duct-facing opening of the cart or the galley compartment. An electronically actuated valve controls a variable flow rate of the cooling air from the air supply duct into the galley cart.

A water supply system for an aircraft having consumers with buffer stores connected to a water tank by lines and a pressure source. Each consumer has a filling valve between the buffer store and the pressure source. The buffer store can be filled by opening the filling valve. In each consumer, water can be removed from the buffer store by opening a consumer valve. Each consumer transmits at least one state parameter describing a state of the buffer store of the respective consumer to a control system. The control system controls opening and closing of the filling valves of the consumers taking into account the transmitted state parameters such that removal of water from the water tank by the pressure source does not exceed a threshold value at any point in time. An aircraft having a water supply system and method for controlling a water supply system are disclosed.

A seat panel for assembly into a rear surface of a seat assembly includes a light assembly which generates task lighting directed to a task area and of sufficient brightness to be useful in performing a task within the task area. The light assembly is selectively actuable to emit light through an aperture defined by the seat panel in a defined light pattern to illuminate a recessed space in the seat panel. The seat assembly when configured as a forward seat assembly of a vehicle provides task lighting for a passenger seated rearward of the forward seat assembly, to illuminate a task area which can include one or more of the exterior surface of the seat panel, a leg space between the forward seat assembly and the passenger's seat assembly, and/or a seat space generally including a portion of the upper leg and/or lap area of the passenger.
