WASHINGTON: The Federal Aviation Administration<\/a> (FAA<\/a>) is confident that aviation safety concerns about 5G C-Band<\/a> deployment will be addressed \"safely with minimal disruptions,\" the head of the FAA<\/a> will tell U.S. lawmakers on Thursday, according to testimony seen by Reuters.
FAA Administrator Steve Dickson will tell a House of Representatives Transportation and Infrastructure subcommittee that in the coming weeks FAA will use testing data to \"safely enable additional 5G<\/a> deployment.\"
The aviation industry<\/a> and FAA has warned 5G<\/a> interference can impact sensitive airplane electronics<\/a> like radio altimeters<\/a>.
Dickson, a pilot, noted radio altimeters<\/a> are one of the most crucial pieces of safety equipment aboard an aircraft and are used in low visibility landings.
\"Harmful interference affecting any of these systems has the potential to be catastrophic,\" Dickson's testimony says. \"There is no scenario under which harmful interference is acceptable from a safety standpoint.\"
On Jan. 17, airlines chief executives warned of an impending \"catastrophic\" aviation crisis that could ground almost all traffic because of the 5G deployment.
Hours before the planned Jan. 19 deployment, Verizon<\/a> and AT&T<\/a> agreed to delay deploying about 510 5G wireless towers near airports.
The delay did not prevent dozens of countries from canceling flights to the United States, and it cast the U.S. regulatory system in an ugly light.
\"Although some flights have been affected by safety mitigations required in 5G deployment areas, significant disruptions to the air transportation system have been avoided,\" Dickson's testimony says.
House Transportation and Infrastructure committee chairman Peter DeFazio in a written statement released ahead of the hearing said that the recent events show \"the current interagency process for auctioning off spectrum is completely broken.\"
DeFazio said key questions remain, including how long will the wireless carriers keep the towners turned off near airports.
Nick Calio, who heads Airlines for America, says in written testimony 5G issues facing the aviation industry<\/a> should have been avoided and it will likely take \"years\" to permanently address interference issues.
The FAA has cleared 20 altimeter models and approved 90% of the U.S. commercial fleet for landing in low-visibility approaches in areas with C-Band 5G.
\"We acknowledge that some altimeters - especially older models used by certain segments of the aviation industry - may not receive approval as being safe in the presence of 5G emissions and interference, and may need to be replaced,\" Dickson's testimony said.
Reuters reported Tuesday https:\/\/www.reuters.com\/business\/media-telecom\/verizon-plans-turn-around-2000-5g-towers-february-sources-2022-02-01 Verizon has won approval to turn on about 14% of the 500 towers it agreed not to deploy near airports. The FAA plans subsequent refinements of the airport buffer zones that will allow further towers to be activated.
Federal Communications Commission<\/a> chair Jessica Rosenworcel was invited but unable to testify. She spoke to DeFazio and subcommittee chair Rick Larsen on Wednesday about the issue, her office said.

美国联邦航空局看到“最小中断”空中旅行从5 g担心安全问题
联邦航空局局长史蒂夫·迪克森会告诉众议院运输和基础设施委员会在未来几周内,美国联邦航空局将使用测试数据“安全启用额外的5 g部署。”
华盛顿:联邦航空管理局(美国联邦航空局)是相信航空安全的担忧5 g c波段部署将“安全用最少的中断,”的负责人美国联邦航空局会告诉美国国会周四,据路透社看到的证词。
美国联邦航空局局长史蒂夫·迪克森会告诉众议院运输和基础设施委员会在未来几周FAA将使用“安全地使额外的测试数据5克部署。”
航空行业和联邦航空局的警告5克干扰会影响敏感飞机电子设备就像无线电测高计。
迪克森,一个飞行员,指出无线电测高计是最重要的部分之一安全设备带上飞机,以及用于低能见度着陆。
“有害干扰影响这些系统有可能是灾难性的,”迪克森的证词说。“没有场景下有害干扰从安全角度来说是可以接受的。”
1月17日,航空公司首席执行官警告说,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。
计划1月19日部署前几个小时,威瑞森和美国电话电报公司(AT&T)同意推迟部署大约510 5 g无线发射塔附近的机场。
延迟并不能阻止几十个国家取消飞往美国,它把美国监管体系在一个丑陋的光。
”虽然有些应对航班受到安全要求在5 g部署地区,严重的干扰到航空运输系统已经被避免,”迪克森的证词说。
众议院运输和基础设施委员会主席彼得·德法兹奥在一份书面声明中公布前的听证会上说,最近的事件显示“目前的跨机构程序来拍卖的频谱是完全坏了。”
看来说关键问题仍然存在,包括无线运营商保持多久去往机场附近。
尼克Calio为美国航空公司负责人说,在书面证词5 g航空面临的问题行业应该是可以避免的,它可能会采取“年”永久解决干扰问题。
美国联邦航空局清除了20高度计模型和批准了90%的美国商业船队降落在不那么出名的方法在c波段5 g的地区。
“我们承认一些高度计,尤其是旧机型所使用的航空工业的某些片段,可能没有得到批准是安全的5 g排放和干扰,并可能需要更换,”迪克森的证词说。
据路透社报道,周二https://www.reuters.com/business/media - telecom/verizon -计划-扭转- - 2000 - 5 g -塔- 2月-资源- 2022 - 02 - 01 Verizon已经获准打开约14%的500年塔同意不部署在机场附近。联邦航空局计划后续细化机场的缓冲区,允许进一步塔被激活。
联邦通信委员会椅子杰西卡Rosenworcel被邀请但无法作证。她说看来,小组委员会主席Rick拉森周三的问题,她的办公室说。
