Processes and systems for determining that a piece of luggage has been left behind in an overhead bin of a vehicle. When a passenger places a piece of luggage into the overhead bin, it is associated with that passenger by detecting that the passenger has sat down in a particular seat after the luggage has been placed into the overhead bin. When it has been determined that the passenger has deboarded the vehicle, and the luggage has not been removed, reminder signals are sent.

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.

A method for testing an audio signal system having multiple audio component connection sockets, each socket having at least one audio signal interface connected to a ground interface of the socket via a series circuit including a resistor and a capacitor, including feeding, via a signal processing device, a time domain reflectometry test signal into a wired network of the audio signal system, in which the sockets are connected to the signal processing device via differently lengthed electrical lines, detecting in a temporally resolved manner, via the signal processing device, test return signals reflected at the multiple sockets, comparing the detected test return signals with a temporally resolved reference pattern for test return signals, which reference pattern was created under predefined boundary conditions, and determining a faulty connection of a socket if comparing the detected test return signals with the reference pattern reveals a deviation above a predefined threshold value.

A method for the automated testing of electrical cabin loads in a cabin of an aircraft comprises activating at least one electrical cabin load in a predetermined operating mode via a test controller; recording an electric power consumption profile of the at least one electrical cabin load in the activated operating mode via a power controller of an electric power distribution system of the cabin of the aircraft, wherein the power controller regulates electric power consumption of the at least one electrical cabin load within the power distribution system; transmitting the recorded power consumption profile to the test controller; and comparing the recorded power consumption profile with a reference profile for the activated operating mode of the at least one cabin load via the test controller, in order to test the at least one electrical cabin load for operability.

In a method for testing an audio communication system of an aircraft, it is detected whether a jack plug of a headset is plugged into a jack of the audio communication system. Subject to the condition that no jack plug is detected, an electrical connection is made between an audio output of the jack and a microphone input of the jack by means of a test bridge circuit provided for at the jack. Furthermore, a test input signal is applied to an audio input connected to the audio output of the jack, and a test output signal is tapped off at a microphone output connected to the microphone input of the jack. The test output signal is used to ascertain a functional state of the audio communication system. Furthermore, an aircraft having an audio communication system is described.

An adapter for tapping into an aircraft panel network in order to provide support for a wireless flight attendant panel (FAP). The adapter includes first and second connectors to insert into the server-to-FAP connection of the panel network and a third connector configured to connect to a wireless access point. The adapter has a housing to which the first, second and third connector are mounted, wherein the housing accommodates power and data connections between the first and second connectors as well as a panel network access connection line between the first connector and the third connector, thereby enabling connection of the panel network to a wireless access point.

Wireless flight attendant panels

The present invention provides a network, in particular for an aircraft and spacecraft, comprising a network line and at least two network access devices which are interconnected by the network line and between which data of different levels of priority can be transmitted, the network access devices being formed so as allocate data with a level of priority allocated to the respective data, at least two different levels of priority being provided for the data depending on the relevance of the respective data, and the data being transmitted on the network line in fixed time slots depending on the level of priority assigned in each case. The present invention further provides a method and an aircraft and spacecraft.
