美国联邦航空管理局表示，美国国内航班可能会在美国东部时间周三上午9点之前恢复。这一声明结束了大约一个小时的停飞，当时该机构正在努力解决一个向飞行员提供安全信息的系统的技术问题。
美国东部时间上午8点50分，美国联邦航空局在推特上写道：”向机组人员提供安全信息的空中任务通知系统中断了一夜之后，美国各地的正常空中交通运营正在逐渐恢复。地面停止已经解除。我们将继续调查最初问题的原因。“

我们将继续调查最初问题的原因
早些时候：周三上午，该机构命令美国航空公司暂停所有国内航班起飞，直到东部时间上午9点，因为该机构正在努力恢复其空中任务通知系统，该系统为航空人员提供与飞行运营相关的关键安全信息。航空行业组织表示，系统问题已经导致全国范围内大量航班延误。
美国东部时间早上6点29分，美国联邦航空局在推特上提醒公众该系统存在问题，并宣布在美国东部时间早上7点19分停飞航班。虽然该机构没有提供系统问题的细节，但路透社报道称，该系统显然已经停止处理更新的信息。
美国联邦航空局解释说，飞行员在起飞前使用NOTAM系统来了解“封闭的跑道、设备故障和飞行路线上或可能影响飞行的位置的其他潜在危险”。根据航班跟踪网站FlightAware的数据，截至美国东部时间上午8点05分，美国境内、境外和入境航班延误3,578次。
“美国联邦航空局仍在努力全面恢复空中任务通知系统，”该机构在早上7点19分在Twitter上更新说，“美国联邦航空局已下令航空公司暂停所有国内航班，直到上午9点。以便该机构验证飞行和安全信息的完整性。”

白宫新闻秘书Karine Jean-Pierre也在周三上午发表了意见，称交通部长Pete Buttigieg 向Joe Biden总统简要介绍了这一情况。政府官员表示，目前没有证据表明NOTAM中断背后是网络攻击。
Jean-Pierre 在推特上说:“今天上午，交通部长向总统通报了联邦航空局系统中断的情况。”“目前没有网络攻击的证据，但总统指示交通部对原因进行全面调查。联邦航空局将提供定期更新。”

The Federal Aviation Administration said that domestic flights in the U.S. could resume shortly before 9 a.m. ET on Wednesday morning.
The announcement ended a period of a roughly an hour.
Which that grounded all flights across the country as the agency struggled to fix technical problems with a system.
Which that provides pilots with safety information
“Normal air traffic operations are resuming gradually across the U.S. following an overnight outage to the Notice to Air Missions system that provides safety info to flight crews,” the FAA tweeted at 8:50 a.m. ET. “The ground stop has been lifted. We continue to look into the cause of the initial problem.”

the agency ordered airlines in the U.S.
Earlier: On Wednesday morning, the agency ordered airlines in the U.S. to pause all domestic departures in the country until 9 a.m. ET as it worked to restore its Notice to Air Missions system, which provides air personnel with critical safety information related to flight operations. Airline industry groups said the problem with system had already caused massive flight delays nationwide.
The FAA alerted the public to a problem with the system at 6:29 a.m. ET on Twitter and announced that it had grounded flights at 7:19 a.m. ET. While the agency didn’t provide details on what had gone wrong with the system, known as NOTAM, Reuters reported that it had apparently stopped processing updated information.
As explained by the FAA, pilots use the NOTAM system before they take off to learn about “closed runways, equipment outages, and other potential hazards along a flight route or at a location that could affect the flight.” As of 8:05 a.m. ET, there were 3,578 delays within, out, and into the U.S., according to flight-tracking website FlightAware.
The FAA is still working to fully restore the Notice
“The FAA is still working to fully restore the Notice to Air Missions system following an outage,” the agency said in a Twitter update at 7:19 a.m. “The FAA has ordered airlines to pause all domestic departures until 9 a.m. Eastern Time to allow the agency to validate the integrity of flight and safety information.”

also weighed in on the outage on Wednesday morning
White House press secretary Karine Jean-Pierre also weighed in on the outage on Wednesday morning, stating that President Joe Biden had been briefed by Transportation Secretary Pete Buttigieg on the situation. Administration officials stated that there was no evidence a cyber attack was behind the NOTAM outage at this time.
“The President has been briefed by the Secretary of Transportation this morning on the FAA system outage,” Jean-Pierre said in a tweet. “There is no evidence of a cyberattack at this point, but the President directed DOT to conduct a full investigation into the causes. The FAA will provide regular updates.”
