Cessna 182 1973 - Oxygen System

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.
