OPERATION
Oxygen from the storage cylinders is fed to the master SUPPLY valve on the flight compartment oxygen
panel on the left console.
Opening the master SUPPLY valve allows oxygen to flow to the contents indicator and the pressure
regulator, then, at 70 psi to the combined mask-regulators, therapeutic outlets and the baromatic valve.
