摘要：
The disclosure relates to a method and a system for detecting the performance of a crew oxygen system (100). The method comprising: obtaining an oxygen pressure of an oxygen cylinder (101) of the crew oxygen system, an ambient air temperature (Tat) and a cockpit temperature (Tc); generating crew oxygen messages from obtained oxygen cylinder of the crew oxygen system, the ambient air temperature and the cockpit temperature; receiving the crew oxygen messages, and determining an oxygen pressure (sensor 230, 300) of the oxygen cylinder under standard temperature; and determining performance of the crew oxygen system.
