全美首批数字塔台在佛罗里达州与阿拉斯加州上线：摄像头360度环视跑道
美国联邦航空局（FAA）11月6日宣布，全美首批数字塔台已在佛罗里达州与阿拉斯加州的两座机场投入运行，空管员自此可借助摄像头与数字显示屏掌握机场动态。
首批启用的两座数字塔台分别位于佛罗里达州的 Bartow Executive Airport 与阿拉斯加州的 Kenai Municipal Airport。数字塔台以先进摄像头和数字显示设备，为管制员提供跑道、滑行道及周边空域连续的360度视野，并附带更多辅助信息，帮助管制员监视机场交通。联邦航空局表示，管制员仍在管理空域，只是如今用上了更现代的技术与设施。
联邦航空局局长 Bryan Bedford 表示，空管员一直在做让飞机安全间隔飞行的关键工作，数字塔台给他们更好的能见度去观察机场活动、更多信息去作关键决策，把更好的工具交到一线人员手中，让他们继续为公众提供安全可靠的空中交通服务。
在特朗普总统的《工薪家庭减税法案》资金支持下，另有五座无塔台机场将陆续装上这套系统：佛罗里达州的 Winter Haven Regional Airport 与 Venice Municipal Airport、马里兰州的 Montgomery County Airpark、北卡罗来纳州的 Johnston Regional Airport，以及科罗拉多州的 Durango-La Plata County Airport。
联邦航空局称，该局此前在新泽西州 Atlantic City 的 William J. Hughes 技术中心等地进行了多年测试，以制定标准、确保数字塔台系统满足该局在安全、准确与可靠性上的要求；最终选定了 Frequentis 公司的系统用于部署。（来源：美国联邦航空局）
First U.S. Digital Air Traffic Control Towers Go Live in Florida and Alaska
The Federal Aviation Administration (FAA) announced on November 6 that the nation's first digital air traffic control towers are now operational at airports in Florida and Alaska, giving controllers better tools to monitor airport activity.
The first digital towers are at Bartow Executive Airport in Florida and Kenai Municipal Airport in Alaska. Digital towers use advanced cameras and digital displays to provide controllers with a continuous, 360-degree view of runways, taxiways and surrounding airspace, along with additional information to support the work controllers already do. The FAA said controllers are still managing the airspace, now with modern technology and facilities.
“Our air traffic controllers continue to do the critical job of keeping aircraft safely separated, and we're giving them better technology to do that,” said FAA Administrator Bryan Bedford. “Digital towers provide controllers with greater visibility of airport activity and more information to make critical decisions.”
With funding from President Trump's Working Families Tax Cut Act, five more non-towered airports will soon receive the systems: Winter Haven Regional Airport and Venice Municipal Airport in Florida, Montgomery County Airpark in Maryland, Johnston Regional Airport in North Carolina, and Durango-La Plata County Airport in Colorado.
The FAA said it conducted years of testing at the William J. Hughes Technical Center in Atlantic City, New Jersey, and other locations to develop standards and ensure digital tower systems meet its safety, accuracy and reliability requirements, and selected the Frequentis system for deployment.
