Sina Technology News Beijing time on January 10 morning news, the US Federal Aviation Administration (FAA) said on Monday that it is proposing a requirement to push US passenger and cargo aircraft to install radio altimeters that can withstand 5G C-band interference by early 2024. Or install an approved 5G signal jammer.
Flights at some U.S. airports were affected earlier this year amid concerns that 5G service could affect planes’ altimeters. The altimeter provides data on the height of the aircraft from the ground, which is essential for aircraft landing in bad weather.
The FAA’s proposed airworthiness directive will take effect in February 2024, similar to another directive that took effect in December 2021. The latter prohibits passenger and cargo aircraft from operating near wireless transmitters in the 5G C-band unless specifically approved by the FAA.
The FAA also put forward another requirement this time, pushing airlines to modify the flight manual of the aircraft to prohibit landing in low visibility conditions after June 30 unless the aircraft has completed the modification required by the directive.
Verizon and AT&T, two major U.S. mobile operators, voluntarily agreed in June last year to partially delay the launch of 5G C-band until July 2023, giving airlines time to complete modifications to their aircraft to ensure they are free from interference from 5G signals. The 2021 FAA directive also relies on voluntary agreements.
However, an FAA official revealed that some international airlines have privately expressed that they are unwilling to install signal jammers unless the FAA makes a legal requirement.
Airlines for America, an industry group representing airlines such as American, Delta and United, said: “Airlines are working hard to ensure that their fleets are equipped with compliant radio altimeters, but the global supply chain remains behind current demand. Any regulation All deadlines set must take this reality into account.”
CTIA, a mobile communications industry organization, said: “The FAA’s altimeter update schedule is reasonable and realistic. 5G C-band can coexist with aviation safety.”
In October last year, Acting FAA Director Billy Nolen (Billy Nolen) hoped to delay the use of 5G C-band by some small operators based on aviation safety considerations. The FAA wants the Federal Communications Commission (FCC) to enforce the voluntary hedging measures AT&T and Verizon agreed to earlier last year on 19 small carriers and other spectrum holders, he said in an Oct. 21 email. .
In January 2022, airline chief executives warned that a “catastrophic” aviation crisis was coming due to the deployment of 5G technology, which could bring nearly all air traffic to a standstill. Still, a deal reached shortly before the 2022 deadline did not stop dozens of foreign airlines from canceling international flights to the United States.
