Design and Implementation of a Scenario Development Process for a 2040 Trajectory-Based Operations Simulation

The National Aeronautics and Space Administration (NASA) is supporting research to transition from a legacy, air traffic management (ATM) system to Trajectory-Based Operations (TBO) environment targeting the 2035-2045 timeframe by creating simulation scenarios for current and future studies. TBO in the National Airspace System (NAS) focuses on modernizing the current operating paradigm to increase efficiency, predictability, resilience, and flexibility while migrating toward greater operational autonomy across the airspace. These simulation scenarios offer a wide dissemination and use of system-level constraints and aircraft state/intent data, routine use of data communications to request complex trajectory modifications and to receive clearances, and aircraft that are flying on 4-D trajectories with flexibility when desired, but structure where required. This report describes the end-to-end development of scenarios for the NASA Langley Research Center simulation environment to represent a 2040 Trajectory-Based Operations airspace for air transport operations research.

Simulation of a Representative Future Trajectory-Based Operations Environment

Trajectory-Based Operations in the National Airspace System is a key aspect of advanced air traffic management research. Trajectory-Based Operations focuses on modernizing the current operating paradigm to increase efficiency, predictability, resilience, and flexibility while migrating toward greater operational autonomy across the airspace. Research conducted at the National Aeronautics and Space Administration supports the transition from current airspace operations to Trajectory-Based Operations targeting a 2035-2045 implementation timeframe. Simulation scenarios that demonstrate a representative Trajectory-Based Operations environment in that timeframe, and enable the evaluation of advanced airborne tools such as strategic airborne trajectory management services, are necessary to support this research effort. This report describes characteristics and assumptions made about the future operating environment that were applied to a scenario development methodology to study a representative 2040 Trajectory-Based Operations environment in a simulation use case. This report also includes descriptions of the study design and analysis approach, discussion of the simulation results, and application of these scenarios to future research activities.

Distributed Simulation Infrastructure for Researching Implementation of Evolving Concepts in the NAS

The National Airspace System (NAS) is evolving; it is becoming more crowded, and new vehicles with different capabilities are starting to utilize airspace. Increased capacity, new vehicles, and their varying performance and equipage profiles will require changes in how we operate in the NAS. The Crew Systems and Aviation Operations Branch (CSAOB) has actively supported crew systems and aviation research contributing to the safe evolution of the NAS. As the NAS continues to evolve to meet the needs of the nation, CSAOB has the history, infrastructure, and tools to support needed research for the introduction of new technologies and understand their impact on the NAS . This paper describes the software infrastructure and tools supported by CSAOB, lists how the tools have been used in the past, how researchers can integrate into our infrastructure, and how these tools are evolving to support research into the future of the NAS.
