FAA Proposes To Ease High-airport O2 Requirements
The FAA has proposed amending aircraft pressurization/oxygen systems to accommodate operations at airports with elevations at or above 8,000 feet msl.

The FAA is proposing to amend certain FAR Part 25 airworthiness regulations regarding pressurization systems and oxygen dispensing equipment on transport-category airplanes to accommodate operations at airports with elevations at or above 8,000 ft msl. Currently, the agency makes a finding of an equivalent level of safety (ELOS) when a manufacturer or modifier proposes to certify cabin pressurization systems for operations at these higher-elevation airports.
