WASHINGTON: The Biden administration does not plan to extend a July 1 deadline for airlines to upgrade airplane altimeters, the measuring instruments that are crucial for bad-weather landings, to address potential interference from 5G<\/a> wireless technology, Transportation Secretary Pete Buttigieg said.
Buttigieg in a call on Tuesday told airlines that the deadline will not be moved. He said airlines had made progress, but urged them to work aggressively to continue retrofitting airplanes, the Transportation Department said.
The Federal Aviation Administration<\/a> (FAA) said last week it did not plan to extend the July 1 deadline before new rules take effect prohibiting certain landings in low-visibility conditions without upgraded altimeters.
Tuesday was the first time in recent months Buttigieg has weighed in on the July 1 date after some airlines pressed hard for a deadline extension.
The International<\/a> Air Transport Association, which represents more than 100 carriers that fly to the United States, said on Tuesday, \"Supply chain issues make it unlikely that all aircraft can be upgraded by the 1 July deadline, threatening operational disruptions during the peak northern summer travel season.\"
Concerns that 5G service could interfere with airplane altimeters, which measure a plane's height above the ground, led to brief disruptions at some U.S. airports last year as international carriers canceled some flights.
Last year, Verizon and AT&T voluntarily agreed to delay some C-Band 5G usage until July 1 as air carriers worked to retrofit airplane altimeters. IATA said Tuesday that \"more is needed\" and said many airlines will have to retrofit most of their aircraft twice in just five years.
On March 31, four major U.S. wireless carriers agreed to some voluntary actions to address aviation safety concerns and allow full use of the C-Band wireless spectrum for 5G use.
Acting FAA Administrator Billy Nolen said last week the FAA has \"given airlines until July of this year to retrofit. Now upon we get to July 1st, if they haven't retrofitted, meaning they will not be able to take advantage of lower visibility approaches that may result in a divert.\" Nolen added that if airlines they have not retrofitted by next year \"they will not be able to operate\" in U.S. airspace.
The agreement with Verizon, AT&T, T-Mobile US and UScellular followed extensive discussions with the FAA, allowing carriers to increase power levels to get to full C-Band use by July 1.
Separately, the FAA on Tuesday proposed seven airworthiness directives for many Boeing aircraft due to the potential for 5G C-band interference.
The proposed directives impact 4,800 U.S. registered airplanes and 14,600 worldwide. They require revising aircraft flight manuals by June 30 to prohibit some landings and include specific operating procedures for calculating landing distances and certain approaches when in the presence of 5G C-band interference.
Boeing said Tuesday that it \"continues to work with suppliers, regulators, the airlines and telecom companies to ensure long-term stability and help mitigate operational restrictions where possible.\"

华盛顿:拜登政府不打算扩大航空公司升级飞机高度计,7月1日最后期限是至关重要的测量仪器;着陆,解决潜在的干扰5克无线技术,交通部长皮特Buttigieg说。
Buttigieg周二在电话告诉航空公司,最后期限不会移动。他表示,航空公司已经取得了进展,但敦促他们工作积极继续改造飞机,交通部门说。
的联邦航空管理局(FAA)上周表示,它不打算延长7月1日的最后期限之前,新规则生效禁止某些没有升级高度计在能见度低的情况下的降落。
周二是近几个月来第一次Buttigieg已经在7月1日日期后一些航空公司按期限延长。
的国际航空运输协会,代表100多个航空公司飞往美国,周二表示,“供应链问题使得它不太可能所有的飞机都可以升级到7月1日的最后期限,威胁操作中断在北部夏季旅游旺季。”
担心5 g服务可能干扰飞机高度计,衡量飞机离地面的高度,导致短暂中断去年在美国的一些机场国际航空公司取消了一些航班。
去年,Verizon和AT&T自愿同意推迟一些c波段5 g使用直到7月1日航空公司致力于改造飞机高度计。国际航空运输协会周二表示,需要“更多”,并表示许多航空公司将不得不改造他们的飞机在短短五年的两倍。
3月31日,四个主要的美国无线运营商同意一些自愿的行动,以解决航空安全问题,允许充分利用c波段无线频谱的使用5克。
代理美国联邦航空局局长比利诺兰说,上周美国联邦航空局“鉴于航空公司直到今年7月翻新。现在在我们7月1日,如果他们还没有翻新,这意味着他们将无法利用低能见度的方法可能导致转移。”Nolen added that if airlines they have not retrofitted by next year "they will not be able to operate" in U.S. airspace.
协议与Verizon, AT&T, t - mobile美国和美国联邦航空局UScellular跟着广泛讨论,允许运营商增加功率得到完整的c波段7月1日使用。
另外,联邦航空管理局周二提出七适航指令对许多波音飞机由于潜在的5 g c波段干扰。
该指令影响全球4800美国注册的飞机和14600。他们需要修改飞机飞行手册在6月30日禁止登陆,包括一些具体操作程序计算着陆距离和某些方法在5克c波段干扰的存在。
波音公司周二说,它“继续与供应商合作、监管机构、航空公司和电信公司,以确保长期稳定和帮助减轻操作限制在可能的情况下。”
