and flow directly to the mask. A feed line directs oxygen to the Oxygen Flow Blinker indicator to show

when the regulator is functioning.

Figure 72: Oxygen Regulator

DILUTER LEVER. The Diluter lever is located on the side of the regulator case and may be

positioned to NORMAL OXYGEN or 100% OXYGEN. The Diluter lever manually operates the air

shutoff valve, allowing the regulator to deliver pure oxygen when the lever is in the 100% OXYGEN

position. During normal operations, the Diluter lever should be left in the NORMAL OXYGEN position

to allow air and oxygen to mix in the proper proportions for any given altitude.

EMERGENCY VALVE. The regulator has an independent oxygen emergency valve. When the valve

is turned counterclockwise, a continuous stream of oxygen is allowed to by-pass the regulator and

flow to the mask.

Recognition Lights

The P-51D is equipped with three recognition lights - red, green, and amber, installed underneath the

right wing. Each light is provided a switch on the Electrical Control panel and can be set to burn

continuously or be flashed on and off by means of a keying switch mounted in a box just above the

Electrical Control panel.
