Tester for testing operational reliability of a cockpit oxygen distribution circuit

摘要

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).
