General:
A low pressure oxygen system is installed which incorporates diluter-demand regulators for the crew. On C-47 and R4D series aircraft, the crew members are supplied by G-1 oxygen cylinders. A diluter-demand oxygen regulator is installed at each flight crew’s station. When oxygen is needed, the tube on the regulator is connected to the hose on the users’s mask. Inhaling opens the valve in the regulator, which automatically supplies a proper mixture of air and oxygen at all times.
Oxygen Regulator Diluter Lever:
A diluter lever is provided on each regulator to select NORMAL OXYGEN for all normal usage or to select 100% OXYGEN for emergency use. When the lever is placed in the NORMAL OXYGEN position, the air inlet valve is opened so that the regulator automatically supplies a proper mixture of air and oxygen to the mask at all altitudes. When the lever is placed in the 100% OXYGEN position, the air inlet valve is closed and the regulator supplies 100% oxygen to the mask.
Oxygen Pressure Gages:
A direct-reading oxygen pressure gage that indicates system pressure is installed at the pilot’s and co-pilot’s stations, up in the cockpit ceiling.
Oxygen Flow Indicators:
An oxygen flow indicator is installed at each flight crew station, up in the cockpit ceiling.
In the current version of the VSKYLABS C-47 Skytrain FLP, the oxygen system is fully functional. Note that the oxygen pressure gages are indicating a single-crew-member.
In the cockpit, there are two W2Ah13d-Leather flight helmets with Type A14 oxygen masks, each one located on each pilot seat arm. To operate, simply click on the helmet/mask. You will then hear the breathing through the mask, and will be able to verify the Oxygen flow by looking up to the cockpit ceiling, checking the Blinker gauge.
Make sure to enable hypoxia in X-Plane's general settings menu, and make sure to breath Oxygen above 10000 feet MSL.
