A hybrid water storage system for an aircraft includes separate variable volumes for respectively storing/holding potable water and gray water occupying a common container. The hybrid water storage system is generally configured to draw potable water from a first variable volume in order to provide fresh water to one or more aircraft appliances (e.g., sinks, showers, ice-makers, etc.), and the used potable water (i.e., the potable water that is collected in drains from the aircraft appliances), referred to herein as gray water, is routed to a second variable volume that occupies the same container as the first variable volume.

A heater for an aircraft component includes a plurality of layers of an additively manufactured conductive ink. The conductive ink is printed on the heater surface, either on a substrate or directly. The heater is protected by a closeout material.

A dual purpose valve assembly may comprise a conduit, a first valve, and a second valve. The first valve may comprise a vacuum breaker valve. The second valve may comprise a check valve. A drain system may comprise a supply tube, a drain tube, and a dual purpose valve disposed between the supply tube and the drain tube. The drain system may allow fluid to drain based on gravity alone, and the dual purpose valve assembly may operate based on gravity alone.

An outside-in liquid purification system includes a housing and a cartridge. The housing defines an interior space and includes an inlet, an outlet, walls extending between a top side and a bottom side, and an unfiltered volume. The cartridge is disposed within the interior space and includes a top cap adjacent the top side of the housing configured to direct liquid that enters the interior space to the unfiltered volume and a filter having an annular shape and extending between the top cap and the bottom side of the housing such that no portion of the unfiltered volume is below the filter with the filter defining a hollow vertical column such that liquid flows from the unfiltered volume through the filter into the column and then downward out of the housing through the outlet.

Outside-in water purification system

A heating arrangement has a positive temperature coefficient ('PTC') heater. A resistor is electrically in series with the PTC heater sized and configured to limit current through the PTC heater and the resistor below a selected value.

An aircraft heated floor panel includes a first support layer, a second support layer, and a heating layer located between the first support layer and the second support layer. An aircraft floor panel includes a floor panel body and a removal feature that provides a mechanism for the aircraft floor panel to be removed from an attached aircraft structure.

Aircraft floor panel

A method of forming a heating element includes depositing a conductive ink of silver particles in an epoxy resin on a dielectric film to create a conductive circuit, and heat curing the conductive circuit to achieve a resistivity of the heating element less than 1.68&#xd7;10ohm&#xb7;meter. An aircraft heated floor panel includes at least one floor panel of an aircraft includes a conductive circuit positioned within the floor panel having a conductive ink of silver particles in an epoxy resin on a dielectric film.
