OXYGEN SYSTEM

A shut-off valve on the rear spar permits shutting off the oxygen supply to all outlets. This valve is normally safetied open. A manually operated flow regulator is at each outlet.

Oxygen is supplied by 10 to 18 oxygen bottles located at various points in the fuselage aft of the flight deck. Airplanes not equipped with auxiliary wing tank fuel cells have only 10 bottles (5 in each wing outboard of wheel wells).
