The EASA requirements for supplemental oxygen in large aircraft cabin (CS 25.1443) correspond to constant flow oxygen systems and test methodologies available at the inception of the rule forty years ago.
The aim of this study was to develop both equivalent requirements and associated Acceptable Means of Compliance (AMC) using the measurement of arterial oxygen saturation (SaO2) of hemoglobin as a more efficient way to assess the performance of oxygen systems to be installed in aircraft. Additionally, the revised requirement will be independent of the technology used.
