WASHINGTON: Air carriers will be unable to fully meet deadlines to retrofit planes to avoid interference from latest generation 5G<\/a> C-Band wireless service, the aviation industry<\/a> said Tuesday, urging the White House to help avert a standoff.
Concerns that 5G services<\/a> could interfere with airplanes' altimeters, which give data on a plane's height above the ground and are crucial for bad-weather landing, led to disruptions at some U.S. airports earlier this year.
A letter signed by Airlines for America, Boeing Airbus, Embraer, aviation unions and others backed the Federal Aviation Administration<\/a> (FAA) request to mandate an extension of mitigation by wireless carriers as airlines retrofit radio altimeters.
\"It is critical to extend these mitigations through the end of 2023 to allow airlines time to complete the retrofit,\" the letter said. Because of global supply chain issues \"air carriers will likely be unable to fully meet either the December 2022 deadlines for smaller regional aircraft and many large transports nor the July 2023 retrofit deadline,\" it added.
\"Our aviation coalition strongly believes that instead of once again waiting until the eleventh hour, now is the time for the leadership at federal agencies and the White House to implement a solution that allows 5G to move forward and avoid further flight delays and cancellations,\" the letter said.
FAA acting Administrator Billy Nolen urged a delay in some 5G C-Band transmissions from smaller operators over aviation safety concerns.
The aviation industry letter said that since January \"the FAA has documented over 100 FAA incidents of potential 5G interference ... Unfortunately, the US government agencies do not appear to be on the same page with respect to these safety issues.\"
The FAA and White House did not immediately comment.
Nolen said in his Oct. 21 letter, which was first reported by Reuters, that the FAA wants the Federal Communications Commission to mandate voluntary mitigations AT&T<\/a> and Verizon<\/a> agreed to earlier this year for 19 smaller telecoms and other spectrum holders.
The aviation letter Tuesday said \"inter-agency government progress appears to be at a stalemate, while stakeholders are doing their part to address these issue.\"
Verizon and AT&T in June voluntarily agreed to delay some C-Band 5G<\/a> usage until July 2023.
Airline CEOs on Jan. 17 had warned of an impending \"catastrophic\" aviation crisis that could ground almost all traffic because of the 5G deployment.
A deal struck shortly before a January deadline did not prevent dozens of foreign carriers from canceling international<\/a> flights to the United States.

美国航空业呼吁5 g无线期限延长
为美国航空公司签署的一封信,波音空客,巴西航空工业公司、航空工会和其他支持美国联邦航空管理局(FAA)请求授权延长缓解无线运营商和航空公司改造无线电测高计。
华盛顿:航空公司将无法完全满足最后期限从最新一代改造飞机避免干扰5克c波段无线服务,航空行业周二表示,敦促白宫,帮助避免僵局。
担心5 g服务可能干扰飞机的高度计,给飞机离地面的高度数据,是至关重要的;降落,导致中断今年早些时候在美国的一些机场。
为美国航空公司签署的一封信,波音空客,巴西航空工业公司、航空工会和其他支持联邦航空管理局(FAA)请求授权延长缓解无线运营商和航空公司改造无线电测高计。
“这是至关重要的扩展这些移植到2023年底,允许航空公司完成改造,”信中说。因为全球供应链问题”航空公司将可能无法完全满足2022年12月的期限为较小的支线飞机和许多大型运输机和2023年7月改造期限,”它补充道。
“我们的航空联盟强烈认为,而不是等到最后时刻再一次,现在是时候领导的联邦机构和白宫实现一个解决方案,允许5 g前进,避免进一步的航班延误和取消,”信中说。
联邦航空局代理管理员比利诺兰敦促推迟一些5 g c波段从小型运营商在航空安全问题。
航空业的信说,自从100年1月“联邦航空局已记录在FAA事件5 g的潜在干扰……不幸的是,美国政府机构似乎没有在相同的页面上对这些安全问题。”
美国联邦航空局和白宫没有立即发表评论。
诺兰说,他在10月21日的信,由路透社首次报道,美国联邦航空局希望联邦通信委员会授权自愿移植美国电话电报公司(AT&T)和威瑞森同意今年早些时候19小电信和其他频谱持有者。
航空信件周二说:“政府机构间进展似乎陷入僵局,而利益相关者也不甘示弱,解决这些问题。”
6月Verizon和AT&T自愿同意推迟一些c波段5克使用,直到2023年7月。
公司ceo在1月17日曾警告说,即将到来的“灾难性”航空危机,地面几乎所有流量,因为5 g的部署。
1月前不久所达成的协议的最后期限没有阻止数十家外国航空公司取消国际飞往美国。
