如今，欧洲空域正面临着多重容量限制，这些限制正在调节一天中忙碌交通时段的需求。这些容量限制通常会导致飞行和机场地面处理效率低下，这预计会增加，因为根据目前的市场预测，客运航空交通需求将继续以每年4.5%[1]至4.8%[2]的速度增长。为了更好地管理稀少的空域容量，根据单一欧洲空中交通管理研究（SESAR）和下一代航空运输系统（NextGen）计划，基于自由航路性能的导航和协调的空域结构被视为有效的缓解措施。然而，随着公众意识的提高和对人为环境影响的更好理解，除了今天的最低燃油和时间目标外，还需要进一步的飞行计划和执行功能。在本文中，我们提出了一个轨迹计算模型，能够利用3D的自由路线优化潜力，同时考虑这些不同的目标，特别是凝结尾迹的成本取决于一天中的时间。该模型在仿真环境TOMATO中进行了案例研究，根据2016年7月的出发机场、到达机场和出发时间，优化了欧洲人一整天的飞行意图。所得到的轨迹进行评估，对分离侵犯的数量。案例研究表明，在考虑所需的航空公司效率、生态兼容性和安全标准时，这种预期的空中交通需求已经强调了自由航线容量。关键词：航迹，空中交通仿真，航迹优化，航迹评估
Today, the European airspace is facing multiple capacity constraints, which are regulating the demand during busy traffic periods of the day. These capacity limits typically cause inefficiencies in flight and in airport ground handling, which are expecting to increase, because according to current market forecasts, passenger air traffic demand will continue to grow between 4.5 percent [1] and 4.8 percent annually [2]. To better manage rare airspace capacity, free routing performance based navigation and harmonized airspace structures are seen as efficient mitigation measures according to the Single European Sky ATM Research (SESAR) and the Next Generation Air Transportation System (NextGen) programs. However, a growing public awareness and a better understanding of the anthropogenic environmental impact necessitates further functions for flight planing and execution, beside today’s minimum fuel and time objectives. In this paper we present a trajectory calculation model capable of exploiting the 3D free route optimization potential while considering these divergent targets, especially the costs of condensation trails depending on the time of the day. The model was implemented in the simulation environment TOMATO for a case study, which optimized the European’s flight intentions for an entire day based on departure airport, arrival airport and departure time on July 2016. The resulting trajectories are evaluated against the number of separation infringements. The case study shows that this anticipated air traffic demand already stresses the free route capacity when considering the required airline efficiency, ecological compatibility and safety standards. keywords: Contrails, Air Traffic Simulation, Trajectory Optimization, Trajectory Assessment
