OXYGEN SYSTEM PRESENTATION (1) Flight Crew Oxygen System The flight crew oxygen system has three sections: The oxygen storage, The oxygen distribution and The oxygen control and indicating.

Storage The flight crew oxygen is stored in a high-pressure oxygen cylinder. This cylinder is located in the upper avionics compartment and placed in a cradle. Optionally the flight crew oxygen system can carry up to four cylinders.

Distribution

LAY08521 - L1502T0 - LM35P4000000001

The oxygen supplies the flight crew stations through a distribution circuit. High pressure is reduced to low pressure by the pressure reducer/transmitter. Low pressure oxygen flows via the low pressure supply valve to the distribution manifold. Then, the manifold supplies the oxygen to the mask stowage boxes in the cockpit. Each mask stowage box has a full face quick donning mask.

Control and Indicating A pushbutton switch, located on the overhead panel, controls the low pressure supply valve. The status of the flight crew oxygen system (oxygen supply pressure, oxygen pressure in the cylinder, high pressure or low pressure warnings) is indicated on the DOOR/OXY page of the ECAM system display (SD).

OXYGEN SYSTEM PRESENTATION (1) Passenger Oxygen System The passenger oxygen system has three sections: The oxygen storage, The oxygen distribution and The oxygen control and indicating.

Storage The oxygen cylinders are installed on the right hand side of the forward cargo compartment. The standard configuration includes three cylinders and up to fifteen cylinders as an option.

Distribution The oxygen supplies the passenger masks through a distribution circuit. High pressure is reduced to low pressure by the pressure reducer/transmitters. Low-pressure oxygen flows via the oxygen regulator to the distribution lines connected to the masks.

Control and Indicating The system can be automatically activated when the cabin altitude exceeds 14000ft, by the Cabin Pressure Control System (CPCS) (application hosted in CPIOM-Bs) through the Oxygen System Control Unit (OSCU), or directly by the altitude pressure switch as a back up. It can also be manually activated on crew action. The "SYS ON" indicator light comes on in both cases. A manual release tool triggers the oxygen container opening. The status of the passenger oxygen system (oxygen supply, oxygen pressure, high pressure or low pressure warnings) is indicated on the DOOR/OXY page of the ECAM System Display.
