Flight crew O2 requirements
I'm in a place where I don't have access to any Boeing data so maybe someone can pitch in here and help me with an oxygen question?
How much time would a crew of three/four have in the event of a smoke and fumes of unknown orgin problem using 100%. Lets just leave the problem itself out of the equation other than saying we need 100% for the duration. I maintain that we need what ever our ETOPS range approval is, but I may be wrong. Lets assume that our crew O2 bottle has been serviced to max or 1800 PSI. I thinking Boeing here but if the Airbus has another approach to this problem, speak up please.
