The National Aeronautics and Space Administration (NASA) has conducted research on a multitude of Air Traffic Management (ATM) areas over the past several decades. The concepts, technologies, and procedures developed through these efforts have meaningfully benefited the flying public and the aviation community in the form of more efficient and predictable operations. Many of these tools and methods were developed for traditional fixed-wing aircraft and passenger-transportation operations. They include technologies for flight planning, scheduling, sequencing, and spacing to a constrained resource such as an airport, dynamic re-routing around weather, traffic flow management, and disruption management.
Recently, NASA has increased its focus on developing technologies and standards for new types of aircraft and missions being pursued by the broader aviation community, such as small unmanned aircraft systems conducting package delivery. NASA’s ATM-X project is working towards integrating new, diverse entrants into the National Airspace System (NAS), while also leveraging NASA’s prior achievements in ATM that continue to improve traditional airspace operations. This includes ATM-X’s Initial Urban Air Mobility (UAM) Operations Integration sub-project, which is conducting research on the airspace integration concepts, technologies, and procedures needed to conduct UAM operations safely and efficiently alongside other airspace users.
UAM-defined as safe and efficient air traffic operations into, out of, and within a metropolitan area by manned aircraft and unmanned aircraft systems-is being researched and developed by industry, academia, and government. The NASA ATM-X UAM sub-project is focused on the airspace integration aspect of UAM both to enable early entrants in the airspace and also to identify, develop, and evaluate the services, procedures, and tools necessary to support high-tempo, high-demand mature UAM operations. UAM operations will leverage and build on an Unmanned Aircraft System Traffic Management (UTM) construct and which includes use of manage by exception paradigm as much as possible, cooperative operations, and application protocol interfaces for a service oriented architecture. Research activities could involve fast-time simulations and/or real-time simulations, the latter of which could include Human in the Loop (HITL) simulations.
The research area for this UAM RFI is intended to address a broad range of collaborative research, development, testing and technology transfer activities and is a separate activity that will move in parallel to NASA’s UAM Grand Challenge to further the maturity of airspace operations to enable highly scaled UAM operations. The product of this collaboration will be requirements to enable high density, safe airspace operations.
The development of an ecosystem for UAM requires input from and collaboration between a wide range of groups. This includes manufacturers of electric vertical takeoff and landing aircraft, manufacturers of avionics and other equipment, builders of takeoff and landing areas, and researchers of the airspace integration concepts, technologies, and procedures needed to conduct UAM operations safely and efficiently alongside other airspace users.
NASA has embraced an agile “Build, Explore, and Learn” collaborative approach for UAM airspace integration and will engage with partners and stakeholders to determine how to work together on research and development activities related to UAM airspace integration. The primary objective sought through this RFI is to evaluate and document the tradeoffs across the wide range of possibilities for UAM airspace integration through coordinated and collaborative research activities in a way that the UAM community at large can use to determine operational performance requirements for UAM vehicles and systems.
To address these airspace integration challenges, the UAM sub-project will undertake the following activities:
- Engineering evaluations of UAM operations in a service-oriented architecture and paradigm (2019)
• Engineering evaluations of a UTM construct for UAM including but not limited to cooperative, intent sharing, operator to operator data exchanges using application protocol interfaces, in a service oriented architecture where many services could be offered by third parties (2019)
• Exploratory research, analysis, and prototype development of new services, tools, and procedures for UAM operations, as well as the adaptation of technologies previously developed for other air traffic operations, such as commercial aviation (2019-2020)
• Engineering evaluations of higher-complexity UAM operations in a service-oriented architecture and paradigm (2020)
• Further development and testing of concepts, architectures, technologies, and procedures for high-complexity UAM operations (2021-2026)
NASA is seeking information and collaboration interest regarding the above plans.
