在到达空中交通管理中，每架飞机都有预定的到达时间，以满足在特定点（例如跑道入口、计量点和汇合点等）与前一架飞机之间所需的时间间隔。通常，交通流中飞机之间的间隔是通过延迟后一架飞机来控制的，这不可避免地导致延误累积和运营效率低下。由于预定到达时间也取决于到达特定点的标称飞行时间，因此可以优化标称飞行时间以最小化整个交通流的运营成本。在这项研究中，标称飞行时间优化策略，通过估计/解决的延误积累，并讨论其可行性。通过数学延迟分析，证明了可以通过使用到达调度的初始点的业务到达的统计来估计延迟累积。通过数值交通仿真，明确证明了优化标称飞行时间的可行性。当标称飞行时间比最小飞行时间长时，可以减少飞行时间。当应用具有飞行时间减少的交通控制时，可以解决延迟累积。它进一步澄清，最佳的预定到达时间可以直接估计从成本函数的单架飞机的情况下，这样的交通无延误积累。此外，最大限度地利用跑道，并同时实现了平等的运作性能。
In the arrival air traffic management, aircraft are provided with each one’s scheduled time of arrival to satisfy the required time interval from the preceding one at a specific point, e.g. runway threshold, metering and merging points, etc. In general, the interval between aircraft in a traffic stream is controlled by delaying the following one, which inevitably results in delay accumulation and operational inefficiency. Because the scheduled time of arrival also depends on the nominal flight time toward specific points, it is considered possible to optimize the nominal flight time to minimize the operational cost of whole traffic stream. In this study, the nominal flight time optimization strategies through the estimation/resolution of the delay accumulation are proposed, and its feasibility is discussed. Through mathematical delay analyses, it is proven possible to estimate the delay accumulation by using the statistics of the traffic arriving at the initial point of the arrival scheduling. The feasibility to optimize the nominal flight time is then clearly demonstrated through the numerical traffic simulation. When the nominal flight time is longer than the minimum one, it is possible to reduce the flight time. When the traffic control with the flight time reduction is applied, it becomes possible to resolve the delay accumulation. It is further clarified that the optimum scheduled time of arrival can be directly estimated from the cost function of a single aircraft in the case of such a traffic free of delay accumulation. In addition, the maximum runway use and the equality of the operation performance are simultaneously achieved.
