In this episode we sit down with Dr. Joey Rios, Chief Technologist for the Aviation Systems Division at NASA Ames Research Center, for a discussion on the evolution of Unmanned Aircraft Systems Traffic Management (UTM). Joey takes us through the early days of UTM development, reflecting on the foundational principles, the initial use cases, and how the vision has evolved over time. We dive deep into the challenges of airspace design, the reasoning behind the U.S. federated model, and how it compares to other global approaches. Joey also shares his perspective on current operations, including the Dallas Operational Evaluation site and how safe BVLOS operations at scale might evolve within and outside of the Mode C veil.
