Hawker 800 XP, Pilot Training Manual

Page: 479 / 504

INTRODUCTION
The Hawker 800 XP oxygen system provides oxygen for crew and passenger use from
two high-pressure steel cylinders. In flight, oxygen is available to the crew at all times.
The passengers’ oxygen is available automatically at high cabin altitudes or manually
anytime at the pilot’s discretion. Oxygen for therapeutic purposes is available at all times
at selected cabin outlets. A portable oxygen system (smoke set) is stowed in the cockpit.
OXYGEN SYSTEM
GENERAL
The oxygen system provides an oxygen supply
to both pilots with a provision for a third
crewmember. Provision is also made for fit-
ting single or dual dropout passenger masks in
the vestibule, the toilet compartment, and the
passenger cabin. Therapeutic outlets are in-
stalled on the airplane as standard equipment.
The system includes two oxygen cylinders (a
third is optional), a pressure regulator, and
crew and passenger oxygen masks. Pressure-
demand regulators are incorporated into the
crew masks. The passenger masks are con-
stant-flow. In addition, the system incorporates
a master supply valve, the barometric valve,
and a passenger supply valve (Figure 17-1).
