“…With FAST, airport throughput increased over 13% without negatively impacting controller workload or safety. 17 While the FAA planned to install FAST at DFW permanently in 1997, that plan changed due to controller concerns that FAST infrequently provided advisories inconsistent with the decisions a controller would make without using FAST.…”

This paper describes past and present air-traffic-management research at NASA Ames Research Center. The descriptions emerge from the perspective of a technical manager who supervised the majority of this research for the last four years. Past research contributions built a foundation for calculating accurate flight trajectories to enable efficient airspace management in time. That foundation led to two predominant research activities that continue to this day -one in automatically separating aircraft and the other in optimizing traffic flows. Today's national airspace uses many of the applications resulting from research at Ames. These applications include the nationwide deployment of the Traffic Management Advisor, new procedures enabling continuous descent arrivals, cooperation with industry to permit more direct flights to downstream waypoints, a surface management system in use by two cargo carriers, and software to evaluate how well flights conform to national traffic management initiatives. The paper concludes with suggestions for prioritized research in the upcoming years. These priorities include: enabling more firstlook operational evaluations, improving conflict detection and resolution for climbing or descending aircraft, and focusing additional attention on the underpinning safety critical items such as a reliable datalink.

“…Dedicated tools such as the Final Approach Spacing Tool and the Advanced Terminal Area Approach Spacing Tool, both developed by the National Aeronautics and Space Administration (NASA), would be employed to support the pilots and air traffic controllers in their task (Davis, Krzeczowski, and Bergh, 1994;Davis et al, 1997;Lee & Davis, 1996;Oseguera-Lohr, Lohr, & Abbot, 2002;Quinn & Robertson, 2000). When an aircraft is cleared for the TDDA, the spacing task is then transferred to the pilot.…”

Previous research on aircraft noise abatement has resulted in some promising flight procedures to mitigate noise impact, such as the three-degree decelerating approach (TDDA). A problem with decelerating approaches, however, is that they typically lead to increased spacing, which in turn results in a significant reduction of runway landing capacity. A possible solution to this problem might be to delegate the task of separating the aircraft during the approach to the pilot. To aid the pilot, an algorithm has been developed that predicts the trajectory of the preceding aircraft and optimizes the flap schedule based on this prediction. Offline simulations indicate that using this system runway throughput numbers of up to 98% of the capacity of a conventional instrument landing system (ILS) approach can be achieved (Ren & Clarke, 2003). To assess practical implementation issues and to investigate pilot appreciation, a piloted experiment was conducted, for which a pilot support interface has been developed that presents the future separation information in an intuitive fashion. The experiment showed that it is indeed possible for pilots to perform the spacing task while flying a TDDA. The pilot support interface significantly reduces pilot workload when compared to a baseline display. Also the effects of off-nominal lead pilot behavior on pilot performance are reduced by the use of online flap schedule optimization and separation prediction.

“…During 1995-1998 period, the Final Approach Spacing Tool (FAST), a component of NASA's Center Terminal Automation System (CTAS), was tested. We do not control for the possible effect of FAST, since it was used on a relatively small number of days, and for just a few hours on these days (Davis et al, 1997).…”
