COCKPIT CREW OXYGEN SYSTEM
The cockpit crew oxygen system supplies oxygen to the flight crew, in case of a sudden decrease in cabin pressurization or if there are smoke or dangerous gases in the cockpit.
CREW OXYGEN SUPPLY
The cockpit crew oxygen system has a high-pressure oxygen cylinder that can be isolated for maintenance by an ON/OFF valve. A pressure regulator reduces the high pressure to a supply low pressure to the masks via a supply valve.
The supply valve can be switched off from the cockpit for maintenance action as well as in ground configuration. The system is protected if an overpressure occurs in a high or low-pressure circuit. The overpressure is vented overboard. The oxygen pressure condition is indicated on the DOOR/OXY page of the ECAM system.
CREW OXYGEN MASKS
The pilots oxygen masks are located in a storage box on both side consoles.
To use the mask the crew member squeezes the red grips to pull the mask out of the box, and this action causes the mask harness to inflate to put the mask on. With the mask in position and the red grips released, the oxygen mask will be supplied with oxygen. A mask-mounted regulator supplies a mixture of air and oxygen or pure oxygen, or gives emergency pressure control. With the regulator set to NORMAL, the user breathes a mixture of cabin air and oxygen up to the cabin altitude at which the regulator supplies 100% oxygen.
The user can select 100%, in that case the regulator supplies pure oxygen at all cabin altitudes.
Depending on the situation, the user can use the emergency rotating knob and receive a maximum of oxygen or with the button pressed the oxygen system can be tested.
A microphone is installed in the mask. A flow blinker flashes when there is an oxygen flow. The TEST AND RESET control enables the oxygen flow to be tested as well as to reset the oxygen system.
