Leakage detection for pressurized fuel tanks. To provide facilitated leakage detection, a leakage detection device for pressurized fuel tanks for storing a pressurized fuel includes a fuel-sensing tracer and a light-wave conducting component. The fuel sensing tracer is configured to alter its optical properties in the presence of a predetermined fuel. The light-wave conducting component is in optical contact with the fuel sensing tracer. Light travelling within the light-wave conducting component is modifiable by altered optical properties of the fuel sensing tracer such that modified light is indicative of the presence of fuel at the location of the fuel sensing tracer.

An indicator apparatus for guiding interior aircraft occupants has a mounting device fastenable to a wall portion of the interior and having an indicator conveying an item of visual information to occupants. An indicator can be or is operated electrically, and the indicator can be or is connected to a power supply for operation. To create an indicator apparatus which helps improve orientation of cabin passengers, can be produced, installed and serviced easily, and which can be operated in a fail-safe manner in an emergency situation of the aircraft, the indicator has an at least one-piece layer, on which circuitry necessary for operation is provided in an integrated fashion, and the power supply is formed by a composite structure battery built up layer by layer and can be or is connected to the layer. A method for producing an indicator apparatus of this kind is disclosed.

A lightweight structure for a vehicle or aircraft includes a longitudinal member with a base bridge, having a first collective conductor and a transversal member with a central bridge and transversal bridge with a first connection conductor extending on a first surface of the transversal bridge and on a second surface of the transversal bridge oriented opposite the first surface, and a second connection conductor extending separately from the first connection conductor. The transversal member is connected to the base bridge at the first end section, so the first connection conductor contacts the first collective conductor of the base bridge. The lightweight structure includes a carbon fiber structural battery (CFSB) connected with the central bridge of the transversal member, a first collector of the CFSB electrically connected to the first or second connection conductor and a second collector of the CFSB electrically connected to the other connection conductor.
