双语：英国将建立首个远程空中交通管制系统

　　伦敦城市机场的空中交通管制塔将被一套远程操作数码系统替代，是英国首例。这意味着空中交通管制员们将无需坐在高塔中眺望飞机跑道，而是在离机场八十英里（约 129 公里）外的地方察看高清摄像机拍下的实时影像。这套新系统计划在 2018 年完成修建，其系统测试期为一年，而最终将于 2019 年正式投入使用。请听 Richard Westcott 的报道。

　　I’m looking at the runway of London City Airport. It’s easy to pick out every detail from the aircraft to people walking around and birds flying nearby. But that runway is actually more than a hundred miles away.

　　The images are being fed onto high-definition television screens because I’m inside Britain’s first digital control tower which, after extensive testing, will eventually go live in 2019.

　　The airport has worked with air traffic controllers at Nats to test the system. They insist it’s safer for many reasons. Controllers can overlay radar data onto the live screens to make it easier to keep track of aircraft. They can zoom in for detail, light up the runway at night, even follow rogue drones straying into dangerous areas. They also insist it’s been independently stress-tested to ensure it can’t be hacked or brought down by power failures.
