The present invention relates to a tester (100) for testing operational reliability of a cockpit oxygen distribution circuit (1) having a plurality of components (20, 30, 40, 50) ensuring supply of oxygen from the cockpit oxygen distribution circuit (1) to a cockpit crew of an aircraft in an emergency situation. The tester (100) comprises means (20', 30', 40', 500 for electrically connecting the tester (100), in place of at least one of the components (20, 30, 40, 50), to the cockpit oxygen distribution circuit (1), an indicator (120) for indicating that the electrical connection of the tester (100) to the cockpit oxygen distribution circuit (1) has been established in a predefined manner, and switching means (RL1, RL2, RL3, RL4) for initiating an output signal of the tester (100), wherein the output signal is indicative of an operating condition of the component (20, 30, 40, 50) when being connected to the cockpit oxygen distribution circuit (1). The invention further relates to the use of such a tester (100) and a method for testing operational reliability of a cockpit oxygen distribution circuit (1).

La présente invention concerne un appareil de contrôle (100) pour tester la fiabilité fonctionnelle d'un circuit de distribution d'oxygène de cabine de pilotage (1), comprenant une pluralité de composants (20, 30, 40, 50) assurant la fourniture d'oxygène depuis le circuit de distribution d'oxygène de cabine de pilotage (1) à un équipage de cabine de pilotage d'un avion dans une situation d'urgence. L'appareil de contrôle (100) comprend des moyens (20', 30', 40', 50') pour connecter électriquement l'appareil de contrôle (100) au circuit de distribution d'oxygène de cabine de pilotage (1), à la place d'au moins un des composants (20, 30, 40, 50), un indicateur (120) pour indiquer que la connexion électrique de l'appareil de contrôle (100) au circuit de distribution d'oxygène de cabine de pilotage (1) a été établie d'une manière prédéterminée, et des moyens de commutation (RLl, RL2, RL3, RL4) pour déclencher un signal de sortie de l'appareil de contrôle (100) ; ce signal étant indicatif d'une condition de fonctionnement du composant (20, 30, 40, 50) quand ce dernier est connecté au circuit de distribution d'oxygène de cabine de pilotage (1). L'invention concerne également l'utilisation dudit appareil de contrôle (100) et un procédé pour tester la fiabilité fonctionnelle d'un circuit de distribution d'oxygène de cabine de pilotage (1).
