导航和数据通信技术的最新进展使得单架飞机能够在空域中存在其他飞机的情况下规划和飞行其轨迹。这样，单架飞机就可以利用大气和交通状况来优化规划其路径。这种能力被称为自由飞行概念。虽然自由飞行概念为飞机运营商提供了新的自由度，但它也带来了当前空中交通管制系统中不存在的复杂性。在自由飞行概念中，每架飞机都有责任在空域内绕行其他飞机。虽然在低速、低交通密度条件下这并不是一项艰巨的任务，但处理多架飞机潜在冲突的复杂性会显着增加飞行员的工作量。本文提出了一种基于拟线性化方法的冲突解决算法的开发，以实现自由飞行概念的实际实现。算法开发使用非线性点质量飞机模型，并结合了对单架飞机的实际操作约束。分析框架还可以包含有关周围大气条件的信息。说明了现实的冲突解决方案。由于其执行速度，这些冲突解决算法适合在飞机上实施。
Recent advances in navigation and data communication technologies make it feasible for individual aircraft to plan and fly their trajectories in the presence of other aircraft in the airspace. This way, individual aircraft can take advantage of the atmospheric and traffic conditions to optimally plan their paths. This capability is termed as the free flight concept. While the free flight concept provides new degrees of freedom to the aircraft operators, it also brings-in complexities not present in the current air traffic control system. In the free flight concept, each aircraft has the responsibility for navigating around other aircraft in the airspace. While this is not a difficult task under low speed, low traffic density conditions, the complexities of dealing with potential conflict with multiple aircraft can significantly increase the pilot’s work load. This paper presents the development of a conflict resolution algorithm based on the quasilinearization method to enable the practical implementation of the free flight concept. The algorithm development uses nonlinear point-mass aircraft models, and incorporates realistic operational constraints on individual aircraft. The analytical framework can also incorporate information about ambient atmospheric conditions. Realistic conflict resolution scenarios are illustrated. Due to their speed of execution, these conflict resolution algorithms are suitable for implementation on-board aircraft.
