Method for controlling an oxygen tank for an aircraft

A method for control of an oxygen tank (1) for aircraft (10), implemented by a processor (12) onboard the aircraft (10), where the method comprises the following steps:

• measuring (20) periodically a current value (Vn) of an oxygen volume in the tank (1) and saving the current value (Vn) in a database;
• calculating (40) an average oxygen consumption flow rate (Qn,k) during an observation period from current values (Vn) stored in the database;
• comparing (80) said average flow rate (Qn,k) with a preset average flow-rate limit;
• detecting a possible state of active oxygen consumption from the tank (1) during the observation period;
• and
• reporting (70) a leak in the tank, if the average oxygen consumption flow rate (Qn,k) is over said preset average flow-rate limit and if no active consumption state was detected during the observation period.
