Compliance verification method on CCAR 25.1443(c) for civil aircraft passenger oxygen system based on blood oxygen saturation

Abstract This paper generally introduces the compliance verification method on airworthiness regulation CCAR 25.1443(c) of popular passenger oxygen system civil aircraft firstly, then technical interpretation <Minimum Mass Flow Supplemental Oxygen> is demonstrated and satisfying this in Top-Down design analyzed. For those based blood saturation which not directly fulfill requirement regulation, equivalent altitude theory established to transform mean tracheal partial pressure required by index altitude, user’s these or higher than that transformed from through actual human body physiological test theoretical analysis aviation physiology, Equivalent Level Safety. gives for have been used gotten approval Authority a type aircraft. also provides basis further revising CCAR25.1443(c).
