AIRPLANE OXYGEN
OPERATIONS
MANUAL
GENERAL
The oxygen system is divided into two different and separate systems:
a gaseous-type for crewmembers (pilot, copilot and observer) and a
chemical generation-type one for passengers and flight attendants.
The crewmembers oxygen is a conventional, high pressure gaseous-
type system, in which the oxygen is stored in a cylinder at high
pressure and distributed at low pressure to the masks.
The passengers oxygen system is supplied through chemical oxygen
generators, which is distributed through dispensing units in several
different locations in the cabin.
For airplanes Post-Mod. SB SB145-35-0008 or equipped with an
equivalent modification factory incorporated, gaseous oxygen supply is
provided in the lavatories.
In addition to the flight crew and passenger oxygen systems,
equipment for smoke protection and fire fighting is provided both in the
cockpit and in the passenger cabin.
The system is monitored so that all the necessary parameters are
informed to the flight crew and flight attendants.
