thanks guys,
i believe boeing had pblished a table of some sort regarding the same.
let me give you a scenario, so that you understand the situation a bit better.
flying in india we operate to an airfield calle leh, its at 10682' amsl.
on this sector we need the special 737s fitted with the 22 min pax oxy system. however the crew oxygen pressure dispatch table is the same!
so this is where i get confused. when the pax oxy requirment is being adhered to by using a larger oxy system for them, why are we being dispatched with the same requirments as any other flight?
we use the 114 cubic foot bottle if that helps.
