NASA开发了终端排序和间隔(TSS)系统，这是一套先进的到达管理技术，结合了基于时间的调度和控制器精确间隔工具。TSS是一种陆基控制器自动化工具，可以方便地对同时具有当前标准ATC路线和基于终端性能的导航(PBN)路线的到达进行排序和合并，特别是在高度拥堵的需求期间。与美国联邦航空局和MITRE先进航空系统开发中心(CAASD)合作，在人在环(HITL)仿真中评估了TSS系统的性能，当前活跃的控制器作为参与者。交通场景有混合区域导航(RNAV)和所需导航性能(RNP)装备，其中装备更先进RNP的飞机享有优先考虑和较短的进场选项。仿真结果表明，TSS系统通过启用PBN获得了好处，同时保持了较高的吞吐速率--比基准需求水平高10%。飞行路径的可预测性提高了，路径偏差平均减少了2 NM，顺风腿长度的方差减少了75%。到达的乘客在更长的时间内飞行的是更省油的下降，在降级高度段平均少花39秒。自我报告的控制员工作量减少，在p<；；0.01水平上有统计上的显著差异。配备了RNP的抵达者还能够更频繁地利用“装备最好、服务最好”(BEB)的好处，那里需要的引导较少，而且几乎所有RNP方法都是不间断地进行的。
NASA has developed the Terminal Sequencing and Spacing (TSS) system, a suite of advanced arrival management technologies combining time-based scheduling and controller precision spacing tools. TSS is a ground-based controller automation tool that facilitates sequencing and merging arrivals that have both current standard ATC routes and terminal Performance-Based Navigation (PBN) routes, especially during highly congested demand periods. In collaboration with the FAA and MITRE's Center for Advanced Aviation System Development (CAASD), TSS system performance was evaluated in human-in-the-loop (HITL) simulations with currently active controllers as participants. Traffic scenarios had mixed Area Navigation (RNAV) and Required Navigation Performance (RNP) equipage, where the more advanced RNP-equipped aircraft had preferential treatment with a shorter approach option. Simulation results indicate the TSS system achieved benefits by enabling PBN, while maintaining high throughput rates-10% above baseline demand levels. Flight path predictability improved, where path deviation was reduced by 2 NM on average and variance in the downwind leg length was 75% less. Arrivals flew more fuel-efficient descents for longer, spending an average of 39 seconds less in step-down level altitude segments. Self-reported controller workload was reduced, with statistically significant differences at the p<;0.01 level. The RNP-equipped arrivals were also able to more frequently capitalize on the benefits of being “Best-Equipped, Best-Served” (BEBS), where less vectoring was needed and nearly all RNP approaches were conducted without interruption.
