Section 5. Oxygen
5.5.10 Cabin/Passenger Oxygen
When the oxygen control knob is in the ON position, low pressure oxygen from the
regulator flows to the three-position PASSENGER MASK selector valve labeled OFF,
AUTO, DROP, on the left switch panel. The cabin oxygen valve is opened one of two
ways:
Electrically, by a solenoid triggered by the 14,000 foot cabin altitude switch
Mechanically, by selecting DROP with the PASSENGER MASK selector
NOTE:
The pilot can deploy the mask at any time without electrical power using this
mode.
When cabin altitude decreases to 10,000 feet the altitude switch resets the solenoid
valve and oxygen flow ceases to the passenger masks. However if the masks are
manually deployed using the DROP selection on the passenger mask selector,
oxygen flow will continue below 10,000 feet.
