WASHINGTON: Two key U.S. House Democrats on Friday urged the Federal Communications Commission<\/a> (FCC) to take action to prevent potential air safety risks from the planned use of C-Band spectrum for 5G<\/a> wireless.
At issue are concerns of potential interference caused by the 5G<\/a> deployment with sensitive aircraft electronics like radio altimeters.
\"We're now on the precipice of a dangerous situation in which the safety of flight hangs on the telecom industry's decision regarding when to switch on its 5G networks,\" said House of Representatives Transportation Committee Chair Peter DeFazio and Representative Rick Larsen, who chairs an aviation subcommittee, in a letter to FCC Chair Jessica Rosenworcel.
A spokeswoman for Rosenworcel did not immediately comment. On Thursday she told reporters she was confident concerns about air safety can be addressed.
The White House National Economic Council was holding a meeting on the issue Friday afternoon, sources told Reuters.
Earlier this month, AT&T and Verizon Communications<\/a> agreed to delay commercial launch of C-band wireless service until Jan. 5 after the Federal Aviation Administration<\/a> (FAA<\/a>) raised safety concerns even as telecom groups warn that a six-month delay in deployment could cost the U.S. $25 billion in economic benefits.
The FAA<\/a> issued a Nov. 2 bulletin warning that action may be needed to address the potential interference caused by the 5G deployment.
The FAA may issue an emergency directive to airlines, and the lawmakers said it could include \"draconian but necessary restrictions on many types of critical flight operations.\"
The two lawmakers asked the FCC to prohibit 5G broadband use in the C-band until the FAA has conducted a robust risk assessment.
The FAA did not immediately comment on the letter Friday.
The lawmakers said Friday that after a year of discussions \"we appear no closer to resolving the serious concerns that the use of the C-band for 5G would create harmful interference.\"
They cited the 2009 Boeing 737-800 accident near Amsterdam as an example of how an \"erroneous radio altimeter reading could potentially result in a fatal air disaster with multiple fatalities, even on a clear day.\"
That crash https:\/\/www.reuters.com\/article\/idINIndia-48276020100506 killed nine people.
People briefed on the matter told Reuters that potential mitigation measures include small exclusion zones around airports, downward tilt of some antennas and reduced power levels to areas around airports.
A coalition of wireless and other trade groups on Thursday told the White House, \"Further delays in launching C-Band could have serious consequences for our nation's ability to leverage the economic growth associated with 5G.\" They argue that there have no been C-Band aviation safety issues in other countries using the spectrum.
Boeing Co, Airbus SE and U.S. airlines have urged administration action to resolve concerns, saying 5G could \"cause harmful interference to radio altimeters, which are crucial systems used by every commercial aircraft and helicopter.\"
The Democratic lawmakers decried what they termed the FCC and telecom industry's \"deploy now, fix later\" approach as \"anathema to the strong safety culture we have created and nourished in aviation over the last 20 years.\"
\"In aviation, we never roll the dice with safety,\" the lawmakers said. \"We never run headlong into a possible hazard to the safety of flight without a full and complete assessment and mitigation of those risks.\"

华盛顿:美国两个关键周五敦促众议院民主党人联邦通信委员会(FCC)采取行动,以防止潜在的航空安全风险的计划使用c波段光谱5克无线。
在问题的担忧潜在的干扰造成的5克部署与无线电高度计等敏感的航空电子设备。
“我们现在悬崖的危险情况的安全飞行挂在电信行业的决定关于何时开关5 g网络,“说众议院交通委员会主席和众议员彼得·德法兹奥里克•拉森航空委员会主席,在一封给杰西卡Rosenworcel FCC椅子上。
Rosenworcel发言人没有立即发表评论。周四她告诉记者,自己是自信的航空安全的担忧是可以解决的。
白宫国家经济委员会周五下午开会的问题,消息人士向路透表示。
本月早些时候,美国电话电报公司(AT&T)威瑞森通讯同意推迟商业发射后的c波段无线服务,直到1月5日联邦航空管理局(美国联邦航空局)提高了安全隐患甚至电信组织警告说,推迟6个月部署可能成本美国250亿美元的经济效益。
的美国联邦航空局发布11月2日公告警告称,可能需要行动来解决潜在的干扰造成的5 g部署。
联邦航空局可能问题紧急指令航空公司和国会议员表示,它可能包括“严厉但必要限制许多类型的关键飞行操作。”
两个议员要求FCC禁止5 g宽带使用的c波段直到联邦航空管理局进行了一个健壮的风险评估。
美国联邦航空局没有立即发表评论这封信。
议员星期五说,经过一年的讨论“我们似乎没有解决的严重担忧c波段5 g的使用会造成有害干扰。”
他们引用了阿姆斯特丹附近的2009架波音737 - 800事故为例,说明一个“错误的无线电高度表阅读可能导致致命的空难与多个死亡,即使在一个晴朗的日子。”
崩溃https://www.reuters.com/article/idinindia - 48276020100506 9人死亡。
知情人士对路透表示,潜在的缓解措施包括机场周围小禁区,向下倾斜的天线和功率降低到周边地区机场。
无线联盟和其他贸易团体周四告诉白宫,“进一步延迟启动c波段可能对我们国家造成严重后果的能力,利用经济增长与5 g有关。”的y argue that there have no been C-Band aviation safety issues in other countries using the spectrum.
波音,空客SE和美国航空公司敦促政府采取行动解决问题,说5 g可能”导致有害干扰无线电测高计,这是至关重要的系统所使用的每一个商用飞机和直升机。”
民主党议员谴责他们称为FCC和电信行业的“部署,修复后”的方法,“诅咒我们创建强大的安全文化和滋养航空过去20年了。”
“在航空,我们从未与安全、掷骰子”议员说。“我们从来没有运行在一个可能的危害飞行安全的不全面和完整的评估和缓解这些风险。”
