NAS Exploratory Concepts & Technologies (NExCT) Upper Class E Traffic Management (ETM) Collaborative Evaluation #1 (CE-1)

NASA, in partnership with AeroVironment and Aerostar, recently demonstrated a first-of-its-kind air traffic management concept that could pave the way for aircraft to safely operate at higher altitudes. This work seeks to open the door for increased internet coverage, improved disaster response, expanded scientific missions, and even supersonic flight. The concept is referred to as an Upper-Class E traffic management, or ETM. NASA and its partners have developed an ETM traffic management system that allows aircraft to autonomously share location and flight plans, enabling aircraft to stay safely separated. This concept was demonstrated during the recent traffic management simulation in the Airspace Operations Laboratory at Ames, data from multiple air vehicles was displayed across dozens of traffic control monitors and shared with partner computers off site. The study details and the initial results are presented at a regular, informal ETM industry meetings held virtually.

ETM: Upper Class E Traffic Management

The FAA, along with input from the National Aeronautics and Space Administration (NASA) and industry partners, published an initial Concept of Operations (ConOps) for Upper Class E Traffic Management (ETM). To support the next iteration of the ConOps, NASA Ames Research Center has been investigating several technologies and operating principles that will help enable industry in the system development of a cooperative operating environment. Following in the footsteps of the established Unmanned Aircraft Systems Traffic Management (UTM) concept, ETM will utilize some of the basic system architecture and the community-based theories of cooperation and coordination. The main considerations for ETM as compared to UTM, are the diversity of the vehicle types with varying speed and maneuverability capabilities, the severe stratospheric atmosphere conditions, the potential longevity of the missions, and the assorted operating modes (e.g., transit, loitering, or hovering). TM oriented technologies and proposed operating principles are being tested and assessed in a collaborative evaluation of an initial ETM system in spring of 2024. These slides will be presented to a group of stratospheric operators, informing them on some past work and the next steps in the ETM research.
