But delays and inefficiencies in air travel are due in large part to an outdated traffic-control system that still relies on slow, ground-based radar stations and repetitive voice communication.
不过航空运输延迟和低效的主要原因还是过时的空中交通管制——一套依靠地面控制、反应迟缓的雷达站和不断重复的语音通讯建立起来的体系。
The present Air Traffic Control (ATC) Geographical Information System (GIS) is very slow in displaying the map due to traversing the whole model to draw all units.
现有空中交通管制(atc)地理信息系统(GIS)重绘时遍历整个地图模型来绘制所有图元，影响了地图显示的速度。
