A system for monitoring traffic in aircraft cabins includes conductive wire in isle carpeting and sensors to register pressure via capacitance changes. The system identifies the volume and location of traffic in aircraft isles via registered changes to voltage, current, and/or conductivity of the conductive wire, and sensors embedded in the carpet. Measurements over time establish changes in traffic flow and directionality which may be used to direct crew members in flight. Lighting elements may be incorporated into the carpet to provide signals to passengers and crew via the lighting elements.

A system may wirelessly supply electrical power to an aircraft cabin component which moves relative to another aircraft cabin component. A first aircraft cabin component may include a solid state electrical power transmitter having an induction loop. The second aircraft cabin component may include a solid state electrical power receiver having a receiving coil. When a power source is connected to the solid state electrical power transmitter, the induction loop creates an oscillating magnetic field which passes through the receiving coil and induces a flow of alternating current through the receiving coil which drives the load.

Disclosed are embodiments of exterior aircraft assemblies integrating compatible elements. In one example, an integrated aircraft assembly includes an aerodynamic housing attachable to an aircraft, an antenna system including at least one antenna element housed within the aerodynamic housing, and a lighting system including at least one light fixture housed within the aerodynamic housing. The at least one antenna element and the at least one light fixture may be co-located within then housing or mounted separately on the housing.
