TAPSS Evaluation of Off-Nominal Events
Researchers at NASA Ames just completed an extensive human-in-the-loop evaluation of the enhanced Terminal Area Precision Scheduling and Spacing to evaluate the effectiveness of the automation for off-nominal conditions. The simulation was very successful and showed that with the automation enhancements the TAPSS system is robust to the critical off-nominal event of missed approaches. The simulation results show that even at the higher levels of throughput afforded by TAPSS the system is controllable with as many as four missed approaches within a 45 minute period which is a critical design issue that is necessary for terminal automation and eventual implementation. The simulation was also visited by members of current operational air traffic controllers from SoCal TRACON. (POC: Harry Swenson)

FAA visits Ames to discuss air traffic management collaborations
FAA traffic flow management leads from the Air Traffic Control System Command Center, the Tech Center and FAA Headquarters visited Ames on September 20-21. The agenda included presentations on NASA's efforts to model the integrated impact of national- and local-level traffic management initiatives, the impact of aviation on the environment, methods for improving the flow of air traffic into Denver during the convective weather season and the Efficient Descent Advisor (EDA). Discussions also included work on sector demand estimation, modeling the integrated impact of pre-departure reroutes and ground holding, and development of a tool to acquire, evaluate and develop data mining techniques using digitized Traffic Management Initiatives. Lastly, a demonstration of the Dynamic Weather Routing tool was provided. Follow-on discussions included an invitation by the FAA to participate in a detailed research gap analysis activity in November to identify areas of mutual interest. (POC: Shon Grabbe)
