Mountain High Earns FAA NORSEE Approval For Oxygen Systems

By General Aviation News Staff · September 20, 2026 · Leave a Comment

Mountain High Equipment & Supply, a manufacturer of aviation oxygen equipment, has received FAA NORSEE approval for some configurations of its EDS-305X Series O2D2 Oxygen Systems.

The EDS-305X Series brings Mountain High’s electronic oxygen-delivery technology into a mounted configuration for eligible certificated aircraft, expanding the installation options available to aircraft owners and pilots, company officials explained.

FAA NORSEE (Non-Required Safety Enhancing Equipment) policy is intended to encourage voluntary safety enhancements in general aviation. The approval framework is based on the principle that the safety benefits of NORSEE equipment should outweigh the potential risks introduced by its installation and operation, and it addresses considerations including system operation, failure conditions, human factors, functionality, limitations, and interaction with the aircraft and pilot.

The Mountain High authorization states that qualifying installations on aircraft certificated under 14 CFR Part 23 or predecessor regulations may be accomplished as minor alterations when the conditions stated in the FAA authorization are satisfied. Installations that constitute major alterations require FAA-approved data through an appropriate approval path.

For pilots and aircraft owners, the NORSEE approval adds another level of confidence to Mountain High’s technology, company officials noted.

The EDS-305X Series is available at MHOxygen.com.
