The pilot's and copilot's masks are equipped with a
microphone to facilitate use of the radio when using
oxygen. An
microphone-equipped mask to mate the mask microphone
lead to the microphone jack located on the left or right side
of the instrument panel. To connect the oxygen mask
microphone, connect the mask lead to the adapter cord and
plug the cord into the microphone jack. If an optional
microphone-headset combination has been in use, the
microphone lead from this equipment is already plugged
into the microphone jack. It will be necessary to disconnect
this lead from the microphone jack so that the adapter cord
from the oxygen mask microphone can be plugged into the
jack. A push-to-talk switch is incorporated on each control
wheel to operate the corresponding microphone.
A remote OXYGEN control lever is located in the overhead console
above the pilot's and copilot's seats and is used to shutoff the supply of
oxygen to the system when not in use. The control lever is
mechanically connected to the shutoff valve at the cylinder. The
OXYGEN control lever is ON when the lever is in the full forward
position and OFF when in the full aft position. With the exception of the
shutoff function, the system is completely automatic and requires no
manual regulation for change of altitude.
The oxygen cylinder, when fully charged, contain either 51 or 117 cubic
feet of aviator's breathing oxygen (Spec. No. MIL-O-27210) under a
pressure of 1960 PSI at 70°F (20°C). Filling pressures will vary due to
ambient temperature in the filling area and the temperature rise
resulting from compression of the oxygen. Filling to 1960 PSI may not
result in a properly filled cylinder. Fill to pressures indicated in Figure
S6-1, Oxygen Filling Pressures, for ambient temperatures.
