- Sequencing and optimal scheduling method was developed for approach control of air traffic to handle increasing traffic volumes. 针对空中交通进近管制地区日益繁忙的交通流量,设计了一种进近排序及优化调度方案。
- Also within each zone are portions of airspace, about 50 miles (80.5 km) in diameter, called TRACON (Terminal Radar Approach Control) airspace. 同样在每一个区域内都有多个直径约为50英里（80.;5公里）的小空域，叫做终端管制（终端雷达近场管制的简称）空域。
- Terminal radar approach control - TRACON handles departing and approaching aircraft within its space. 终端雷达管制区（TRACON）-负责本区内飞机的起落。
