Flight Crew Oxygen Requirements
Regulations require that sufficient oxygen be provided to the flight crew to account for the greater of supplemental breathing oxygen in the event of a cabin depressurization or protective breathing in the event of smoke or harmful fumes in the flight deck.
The good old reliable Boeing, at 15 degrees bottle pressure for dispatch for a crew of 2 3 and 4 needs to be:
470/655/840 PSI for the 115/114 Cu Ft Bottle Installation.
655/940/1215 for the 76 Cu Ft Bottle Installation
Check your aircraft’s specific manuals for minimum requirements for dispatch. Your company specific may require greater bottle pressure for dispatch above the manufacturers certified minimum.
