WASHINGTON: A group representing major U.S. airlines \"strongly urged\" the Federal Aviation Administration (FAA) to extend a proposed deadline to June 2024 to retrofit airplane altimeters to ensure they are not susceptible to 5G<\/a> wireless interference.
Airlines for America (A4A), which represents American Airlines, Delta Air Lines<\/a>, United Airlines and others also asked the FAA to revise a proposed 5G safety directive \"to reflect technical realities and the continued safe operation of many aircraft.\" The group warned a \"material number of aircraft\" in U.S. fleets will not be modified by July and without changes it could \"severely limit operations\" and lead to flight delays and cancellations.
Wireless carriers opposed the request.
In January, the FAA proposed requiring passenger and cargo aircraft in the United States to have 5G C-Band-tolerant radio altimeters or approved filters by February 2024. The agency reiterated on Friday it will evaluate all comments.
Concerns that 5G service could interfere with airplane altimeters, which give data on a plane's altitude and are crucial for bad-weather landing, led to disruptions at some U.S. airports last year involving international<\/a> carriers.
Also Friday, a coalition including Boeing, Airbus Lockheed Martin, Raytheon, pilots unions, and airlines said the directive \"does not provide sufficiently robust controls to ensure safety as both aviation operations and wireless services co-evolve\" and does not include a realistic cost estimate.
Verizon Communications<\/a> and AT&T<\/a> in June voluntarily agreed to delay some C-Band 5G use until July as air carriers work to retrofit airplanes to ensure they will not face interference.
Wireless carries spent more than $80 billion on the C-Band 5G spectrum, including $52.9 billion by Verizon<\/a> in auction and clearing costs. The FCC did not comment.
Wireless trade group CTIA, which represents Verizon and AT&T, said the FAA provided ample time for airlines and should not extend the deadlines.
\"By requiring accountability, the FAA is taking important steps to ensure radio altimeter performance is more resilient while enabling timely C-Band 5G deployment,\" CTIA said.
The International Air Transport Association (IATA), which represents more than 100 carriers flying to the United States, warned costs would be far higher than the $26 million estimated by FAA. IATA said costs could be at least $637 million and said many airlines risk missing deadlines.

美国航空公司敦促联邦航空局延期5 g升级
美国航空公司(A4A),代表美国航空公司、达美航空公司,美国联合航空公司以及其他还要求美国联邦航空局修改提出了5 g安全指令”,以反映技术现实和许多飞机的持续安全运行。”The group warned a "material number of aircraft" in U.S. fleets will not be modified by July and without changes it could "severely limit operations" and lead to flight delays and cancellations.
华盛顿:一组代表美国主要航空公司“强烈敦促美国联邦航空管理局(FAA)延长了期限到2024年6月改造飞机高度计以确保他们不容易5克无线干扰。
美国航空公司(A4A),代表了美国航空公司,达美航空公司、美国联合航空公司以及其他还要求美国联邦航空局修改提议5 g安全指令”,以反映技术现实和许多飞机的持续安全运行。”The group warned a "material number of aircraft" in U.S. fleets will not be modified by July and without changes it could "severely limit operations" and lead to flight delays and cancellations.
无线运营商反对请求。
今年1月,美国联邦航空局提议要求客运和货运飞机在美国有5 g C-Band-tolerant无线电测高计或过滤器通过2024年2月。该机构周五重申,将评估所有评论。
担心5 g服务可能干扰飞机高度计,这给数据在飞机上的高度和欢笑着陆的关键,导致破坏美国的一些机场去年涉及国际运营商。
同样在上周五,联合包括波音、空客洛克希德·马丁公司,雷神公司和航空公司飞行员工会说,指令“没有提供足够强大的控制,确保安全作为航空业务和无线服务”共同演化,不包括一个现实的成本估计。
威瑞森通讯和美国电话电报公司(AT&T)6月自愿同意推迟一些c波段5 g使用到7月与改造工作的航空公司飞机,以确保他们不会面临干扰。
无线承载c波段5 g上花了超过800亿美元,包括529亿美元威瑞森在拍卖和清算费用。FCC没有置评。
CTIA无线贸易组织代表Verizon和AT&T表示,美国联邦航空局为航空公司和提供了充足的时间不应该延长期限。
“要求问责制,联邦航空局正在采取重要步骤确保无线电高度表性能更有弹性,使及时c波段5 g部署,“CTIA说。
国际航空运输协会(IATA),代表超过100个航空公司飞往美国,警告成本将远远高于估计的2600万美元联邦航空局。国际航空运输协会说,成本可能至少6.37亿美元,许多航空公司风险错过最后期限。
