An apparatus (10) for fuelling an aircraft, in particular during performing a tank leakage test on the aircraft, com-prises 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).

La présente invention concerne un appareil (10) permettant d'avitailler un aéronef, en particulier, pendant l'exécution d'un essai d'étanchéité du réservoir sur l'aéronef. Cet appareil comprend une conduite d'alimentation en carburant (14) conçue pour assurer l'alimentation en carburant d'un système de réservoir (12) d'aéronef, au moins un capteur de pression (26) permettant de capter une pression à l'intérieur du système de réservoir (12) d'aéronef et de fournir un signal indiquant la pression à l'intérieur du système de réservoir (12) d'aéronef, un bloc de commande électronique (ECU) conçu pour traiter le signal du capteur de pression (26) et pour générer un signal d'arrêt d'urgence, si la pression à l'intérieur du système de réservoir (12) dépasse un premier niveau prédéterminé, et un dispositif d'arrêt d'urgence (24) commandé par le bloc de commande électronique (ECU) et conçu pour interrompre l'alimentation en carburant du système de réservoir (12) en réponse au signal d'arrêt d'urgence transmis par le bloc de commande électronique (ECU).
