2023年7月28日 · Upper Class E airspace operations refer to those that take place over 60,000 feet above mean sea level (MSL) in the National Airspace System (NAS). Operations in upper Class E airspace have historically been limited due to the challenges faced by conventional fixed wing aircraft in reduced atmospheric density.

The FAA is collaborating with NASA and aviation industry stakeholders on the Upper Class E Airspace Traffic Management (ETM) Concept of Operations (ConOps) to develop a vision for managing flights above 60,000 feet. Joint engineering analyses and simulations will inform the ConOps, which will describe a cooperative traffic.

ETM is comprised of highly automated and third party-managed services that apply commercial practices to safely scale service growth in line with demand. ETM allows for the flexible use of airspace through cooperative traffic management among operators where air traffic services are not provided or available. Outcome(s)
