OXYGEN
SYSTEM
A
four-place
oxygen
system is
available
for
your
airplane.
In
this
system,
an oxygen
cylinder,
located behind the
rear
baggage
compart-
ment wall, supplies the oxygen. Cylinder
pressure is reduced
to an op-
erating pressure
of 70
psi
by
a
pressure regulator attached
to
the
cylin-
der.
A
shutoff valve
is
included
as part
of
the
regulator assembly.
An
oxygen
cylinder filler
valve
is located
on
the
left
side
of
the
rear
baggage
compartment
wall.
Cylinder
pressure is indicated
by
a pressure
gage
located
in
the
overhead
oxygen console.
.
Four oxygen
outlets are
provided;
two
in the overhead oxygen console
and
two
in the cabin ceiling
just
above the side windows;
one
at each
of
the
seating
positions.
One
permanent,
microphone-equipped mask
is
provided
for the pilot, and
three
disposable type
masks are
provided
for
the
passen-
gers.
All
masks are
the
partial-rebreathing
type equipped with vinyl
plastic hoses
and flow
indicators.
A
remote
shutoff valve control, located adjacent to the
pilot's
oxygen
outlet,
is
used to shut
off
the supply
of
oxygen to the
system
when
not in
use.
The
control is mechanically
connected to the shutoff valve at the
cylinder.
With the exception
of
the shutoff function, the
system is com-
pletely
automatic
and
requires
no
manual
regulation
for change
of
altitude.
OXYGEN
SYSTEM
OPERATION.
Prior
to
flight, check
to be
sure
that
there is
an adequate oxygen
supply
for
the
trip,
by
noting the oxygen
pressure
gage
reading. Refer
to
paragraph
OXYGEN DURATION CALCULATION,
and to the Oxygen
Duration
Chart
(figure 7-2). Also, check
that
the face
masks
and
hoses
are accessible
and in good condition.
Supplemental oxygen should
be
used
by
all
occupants when
cruising
above 10,000 feet. As
described
in the
Cessna
booklet "Man At Altitude,
"
it is
often advisable to use oxygen at
altitudes
lower than
10,
000
feet
under conditions
of
night flying, fatigue,
or periods
of
physiological or
emotional
disturbances.
Also, the habitual and
excessive
use
of
tobacco
or
alcohol will usually
necessitate
the use
of
oxygen at
less
than
10, 000
feet.
