crew, cabin
Attendants and passengers. Oxygen can be
used for these
Reasons:
* Life sustaining oxygen if the plane depressurizes

General Description
The flight crew oxygen system operates
independently of the
Other systems. It is a high pressure gaseous
system. High
Pressure gaseous oxygen is in a cylinder in
the EE
Compartment. The manifold supplies oxygen to
the flight crew
Oxygen masks.
The passenger oxygen system uses chemical
oxygen
Generators. The generators are in the
passenger service
Units (PSUs). Each chemical generator is
separate, and
Supplies only its masks. The masks connect
to the chemical
Générateurs
by flexible tubes.
