美国作为世界上航空业最为发达的国家之一,自50年代起从未间断过机场及空域的容量研究,迄今为止,美国联邦航空局(FAA)已经拥有覆盖空中交通管制各个阶段的容量评估软件,形成了一套有效的评估体系和研发机制。一、FAA容量软件评估体系1.评估模型FAA采用的容量评估模型有两大类:数学模型和仿真模型。数学模型主要是采用时空分析方法对空域单元进行数学建模,可对空域单元的最大容量(又称饱和容量,反映延误趋于无穷大时系统的极限服务
As one of the most developed nations in the world in the aviation industry, the United States has never stopped researching the capacity of airports and airspace since the 1950s. To date, the FAA already has capacity assessment software covering all phases of air traffic control , Formed an effective evaluation system and research and development mechanism. First, the FAA software capacity assessment system 1. Evaluation Model FAA capacity assessment model used in two categories: mathematical models and simulation models. The mathematical model mainly uses the method of spatiotemporal analysis to mathematically model the airspace unit, and can calculate the maximum capacity of the airspace unit (also known as the saturation capacity, which reflects the limit service of the system when the delay tends to infinity
