A test module for functionally testing an audio device of an aircraft passenger service unit (PSU) is configured to allocate a first operating mode to a first individual audio device of one PSU of a set of PSUs during which, a test tone is emitted. The test module allocates a second operating mode to other audio devices different than the first audio device. In the second operating mode, the test tone emitted by the first audio device is intended to be received. The other audio devices each belong to different PSUs within the set of PSUs. The test module emits the test tone via the first audio device. The test module initiates a functional test of the first audio device. The functional test is based on the test tone received by the other audio devices. The test module may be part of a system and an aircraft.

Automated self-test of cabin loudspeakers

A passenger supply unit for an aircraft cabin, including an input device for detecting a control command from a passenger, and for outputting a control signal to a further device for controlling the further device according to the control command. A passenger supply unit can be controlled by a passenger independent of its height above the passenger seat. The unit can be independent from an in-flight entertainment system. The input device includes a contact free sensor to detect the control command without being contacted by a passenger.

An electronic baggage stowage system for an aircraft comprising a first detector to detect free space in a cabin stowage space, wherein the first detector is configured to output cabin stowage space data based on the detection, a processing unit communicating with the first detector, wherein the processing unit is configured to process the cabin stowage space data, receive and process baggage size data indicating the size of one or more baggage items, and output baggage stowage mapping data in response to the processing of the cabin stowage space data and the baggage size data. The baggage stowage mapping data indicates one or more target positions in the cabin stowage space at which the baggage items are to be placed. An indicator communicates with the processing unit to provide the indication of the one or more target positions to a flight attendant or passenger of the aircraft.
