美国各地的航空旅行中断预计将持续到周日，数千个航班被取消或延误，航空公司正努力在联邦航空管理局（FAA）空中交通管制通信系统出现问题引发全国性停飞后恢复正常运营。
FAA局长布莱恩·贝德福德周六表示，即使该机构正在努力稳定运营并解决导致中断的技术问题，航班时刻表也不太可能在周日晚些时候前恢复正常。
Air travel disruptions across the United States are expected to continue well into Sunday, with thousands of flights cancelled or delayed as airlines struggle to restore normal operations following a nationwide shutdown triggered by problems in the Federal Aviation Administration's (FAA) air traffic control communications system.FAA chief Bryan Bedford said on Saturday that flight schedules were unlikely to return to normal until late Sunday, even as the agency worked to stabilise operations and address the technical issues behind the disruption.
据航空追踪网站FlightAware统计，截至美国东部时间周六下午6点45分（格林威治标准时间23时45分），美国各地航空公司已取消6150多个航班，延误7300多个航班。此次中断继周五更糟糕的一天之后发生，当时约有9200个航班被取消，7500个航班延误。截至周六晚间，周日计划的航班中也已有530多个被取消。
Airlines had cancelled more than 6,150 flights and delayed over 7,300 others across the US by 6.45 pm ET (2345 GMT) on Saturday, according to aviation tracking website FlightAware. The disruption followed an even worse day on Friday, when around 9,200 flights were cancelled and 7,500 delayed. More than 530 flights scheduled for Sunday had also been cancelled by Saturday evening.
贝德福德就此次中断向乘客道歉，称航空系统保持稳定，FAA预计到周日晚些时候运营将基本恢复。
Bedford apologised to passengers for the disruption, saying the aviation system remained stable and that the FAA expected operations to largely recover by late Sunday.
持续的中断导致数千名乘客滞留机场，航空公司面临着重新调配飞机、飞行员和其他机组人员以恢复正常时刻表的额外挑战。技术故障导致全国性航班停飞此次中断始于周五，当时FAA下令全国性停飞，暂停了几乎所有出港航班近五个小时。这是自2001年9月11日袭击事件以来最长的全国性航空旅行暂停，也是美国航空旅行最糟糕的单日之一。
The continuing disruption has left thousands of passengers stranded at airports, with airlines facing the additional challenge of repositioning aircraft, pilots and other crew members to resume regular schedules.TECHNICAL GLITCH BEHIND NATIONWIDE FLIGHT SHUTDOWNThe disruption began on Friday after the FAA ordered a nationwide ground stop, halting almost all departing flights for nearly five hours. It was the longest nationwide suspension of air travel since the September 11, 2001 attacks and one of the worst single days for US air travel.
白宫在其形势室召开紧急会议，官员最初调查此次中断是否可能由网络攻击引起。
The White House convened an emergency meeting in its Situation Room as officials initially examined whether the disruption could have been caused by a cyberattack.
然而，交通部长肖恩·达菲表示，问题被追溯到联邦航空管理局（FAA）承包商L3哈里斯公司在一处偏远设施安装了至少一台新路由器。达菲说，该机构仍在调查故障是源于安装过程中的操作失误，还是设备本身存在缺陷。“我们正在努力确定是否存在无能的情况，也就是说是用户失误，还是L3哈里斯的安装人员失误，又或者他们安装了一台有缺陷的路由器？我们尚未确定故障所在，”他对记者说。L3哈里斯表示，正严肃对待此事，并协助联邦航空管理局进行调查。
However, Transportation Secretary Sean Duffy said the problem was traced to the installation of at least one new router by FAA contractor L3Harris at a remote facility. Duffy said the agency was still investigating whether the failure resulted from human error during installation or a faulty piece of equipment." We're working to determine whether we had incompetence, meaning was it user error or installer error from L3Harris, or did they install a faulty router? We haven't determined what the fault was," he told reporters.L3Harris said it was taking the matter seriously and assisting the FAA with its investigation.
据官员称，路由器故障导致其他通信中心数据过载，扰乱了空中交通管制员使用的雷达和通信系统。达菲说，系统每四到五秒就经历了超过1000次连接尝试，影响了与飞机的通信并导致雷达中断。该问题波及联邦航空管理局22个航路空中交通管制中心中的17个，这些中心负责管理飞机巡航阶段的飞行。贝德福德表示，实施停飞令是一种预防措施，以防任何中心完全丧失通信能力。然而，没有任何设施完全失去服务。
According to officials, the router malfunction caused an overload of data at other communications centres, disrupting radar and communication systems used by air traffic controllers. Duffy said the system experienced more than 1,000 connection attempts every four to five seconds, affecting communications with aircraft and causing radar disruptions. The problem affected 17 of the FAA's 22 en route air traffic control centres, which manage aircraft during the cruising phase of flights. Bedford said the ground stop was imposed as a precaution in case any centre lost all communication capabilities. However, no facility completely lost service.
联邦航空管理局表示，正与L3哈里斯进行额外测试，以确定是否仍存在进一步风险。航空公司取消数千航班，恢复需时主要美国航空公司周六继续面临大规模取消航班的局面。
The FAA said it was carrying out additional tests with L3Harris to determine whether any further risks remained.AIRLINES CANCEL THOUSANDS OF FLIGHTS AS RECOVERY TAKES TIMEMajor US carriers continued to face widespread cancellations on Saturday.
达美航空、联合航空和美国航空各自取消了约四分之一的计划航班，而捷蓝航空取消了近 45% 的航班，据 FlightAware 数据显示。航空公司已提供旅行豁免，允许受影响乘客在不支付额外费用的情况下将行程改订至稍后日期。尽管美国联邦航空管理局（FAA）于周五晚间解除了全国性停飞令，但影响持续存在，因为航空公司正努力将飞机、机组人员和其他人员调回岗位。
Delta Air Lines, United Airlines and American Airlines each cancelled around a quarter of their scheduled flights, while JetBlue cancelled nearly 45 per cent, according to FlightAware. Airlines have offered travel waivers allowing affected passengers to rebook their journeys for later dates without paying additional fees. Although the FAA lifted the nationwide ground stop on Friday evening, the impact continued as airlines worked to get aircraft, flight crews and other personnel back into position.
此次中断还影响了前往参加周六比赛的大学橄榄球队，部分球队周五被困。美国寻求数十亿美元资金翻新老化空管系统此次中断重燃了人们对美国空管网络状况的担忧，该网络面临着技术老化、设备和通信故障，以及数千名空管人员短缺的日益增大的压力。达菲呼吁提供 500 亿美元资金以实现系统现代化，较他早前提出的 300 亿美元有所增加。
The disruption also affected college football teams travelling for matches scheduled on Saturday, with some left stranded on Friday.US SEEKS BILLIONS TO OVERHAUL AGEING AIR TRAFFIC SYSTEMThe disruption has renewed concerns about the condition of the US air traffic control network, which has faced mounting pressure from ageing technology, equipment and communication failures, as well as a shortage of several thousand air traffic controllers. Duffy has called for $50 billion in funding to modernise the system, raising his earlier request of $30 billion.
国会去年已批准 125 亿美元用于升级。众议院议长迈克·约翰逊周六表示，他支持今年批准用于空管基础设施的额外资金。与此同时，预计明年将分别领导众议院交通和基础设施委员会及其航空小组委员会的民主党议员里克·拉森和安德烈·卡森表示，他们将举行听证会审查此次中断。他们还质疑现有现代化计划下的支出进度，称交通部已授予价值 43 亿美元的合同，但仅花费了国会去年批准的 125 亿美元中的 10 亿美元。—— 完 ——路透社供稿
Congress had approved $12.5 billion for upgrades last year. House Speaker Mike Johnson said on Saturday that he supported approving additional funding for air traffic infrastructure this year. Meanwhile, Democratic lawmakers Rick Larsen and Andre Carson, who are set to lead the House Transportation and Infrastructure Committee and its aviation subcommittee next year, said they would hold hearings to examine the disruption. They also questioned the pace of spending under the existing modernisation programme, saying the Transportation Department had awarded contracts worth $4.3 billion but spent only $1 billion of the $12.5 billion approved by Congress last year.- EndsWith inputs from Reuters
