General
The aircraft is equipped with two
independent oxygen systems. One oxygen
system is installed in the cockpit for the Flight
Crew, and the other oxygen system is
installed in the passenger compartment for
the passengers and Flight Attendants.
Flight Crew Oxygen System
Oxygen to the Flight Crew is supplied from a
high-pressure gaseous oxygen supply
cylinder.
For normal operation of the system the
supply toggle switch must be set to ON, the
diluter control switch to NORMAL OXYGEN
and the TEST MASK/NORMAL/EMERGENCY
switch to NORMAL. This setup will supply
oxygen to the masks upon demand.
In the event of a cabin decompression at
altitudes above 28,000 feet, the system will
automatically sense the change in cabin
pressure and supply the masks with 100%
pure oxygen.
In the event of an emergency where
protective breathing is required (such as
smoke in the cabin, etc.) the diluter control
switch must be set to the 100% OXYGEN
position.
If a oxygen regulator failure occurs, the
diluter control switch must be set to 100%
OXYGEN and the TEST
MASK/NORMAL/EMERGENCY switch must be
set to EMERGENCY. (The TEST
MASK/NORMAL/EMERGENCY switch is
currently not simulated)
