Abstract: An apparatus (10) for fuelling an aircraft, in particular during performing a tank leakage test on the aircraft, comprises a fuel supply line (14) for supplying fuel to an aircraft tank system (12), at least one pressure sensor (26) for sensing a pressure within the aircraft tank system (12) and for providing a signal indicative of the pressure within the aircraft tank system (12), an electronic control unit (ECU) for processing the signal of the pressure sensor (26) and for generating an emergency shut-off signal, if the pressure within the aircraft tank system (12) exceeds a first predetermined level, and an emergency shut-off device (24) which is controlled by the electronic control unit (ECU) and which is adapted to interrupt the supply of fuel to the aircraft tank system (12) in response to the emergency shut-off signal from the electronic control unit (ECU).

Abstract: An apparatus for pressurizing an aircraft cabin structure and measuring the amount of leakage of the aircraft cabin structure comprises an air supply line which at a first end is connectable to a pressurized air source and which at a second end is connectable to the aircraft cabin structure so as to supply pressurized air from the pressurized air source into the aircraft cabin structure, an air supply valve disposed in the air supply fine, a pressure sensor for sensing the pressure inside the aircraft cabin structure and for providing signals indicative of the pressure inside the aircraft cabin structure, an air discharge line which at a first end is connectable to the aircraft cabin structure and which at a second end is connectable to an air discharge opening so as to discharge air from the inside of the cabin structure to the air discharge opening and an air discharge valve disposed in the air discharge line.
