Trajectory-Based Operations (TBO) Study Team Report Preface The Joint Planning and Development Office (JPDO) formed a government/industry study team in December 2009 to develop operational scenarios and architectural use cases to help define Trajectory- Based Operations (TBO). The study team’s approach was to create some gate-to-gate flights and ask questions on how TBO would work beyond the 2025 timeframe. This TBO Study Team’s processes included input to the Integrated Work Plan (IWP), findings and recommendations, and a decomposition of the narratives into discrete action steps called use cases. These use cases are being used to develop changes to the Next Generation Air Transportation System (NextGen) Enterprise Architecture. This final version of the report contains recommendations on new operational improvements, research, policy, and procedures that would be necessary to implement TBO. This report is useful in defining a far-term operational approach for TBO. The Federal Aviation Administration (FAA) has developed an operational approach for the initial mid-term use of trajectories, called trajectory operations (TOps), that is linked to the FAA’s mid-term (2012-2018) concept of operations. While the TBO Study Team was focused on a far-term timeframe defined by the FAA as 2018 to 2025, TBO will require considerable research and engineering development. While elements of TBO may start in the 2018 to 2025 timeframe, full use of the advantages of TBO are expected to occur beyond 2025. Operational scenarios presented do not represent the final concept of operations for TBO, rather they are a starting point to begin the dialog on what TBO is and how it will operate in NextGen. The team agrees that the main purpose is to begin the dialog on the functional requirements for TBO and to make the transition from use of trajectories in TOps to TBO as seamless as possible, especially to the users of NextGen. Many terms and procedures discussed in the report require refinement by research and development. Joint Planning and Development Office i
