flights canceled due to 5G concerns
Discussion
seems boeing think the 777 doesnt play nicely with 5g could end up with diehard 2 oops
so verizone and at&t and postponing rollouts of masts near major airports. so why hasnt it been in issue here or dont we have any 5g services near airports?
see the flat earth, anti vax, space laser community were right the 5g is hear to kill you

I think I understand what you are trying to say (your use of the English language is rather unique, I have to say).
Aircraft like the 777 are almost 30 year old designs now and although many of the airframes in service today are newer models, much of the technology contained in them, including the electronics, would have been based on the world as it was around 1990, not 2021.
It's hard to anticipate where technology will be so far into the future.

yes but you would have thought the fcc and faa would have thought these issues might occur since in europe they implemented mitigating practises to avoid potential issues
as you say the equipment altimeters have been in service for years so they should know already what frequency's they are not shielded against

The same kind of thing happened in the UK about 20 years ago - extensions to the FM radio spectrum allocation crept up to the base of the aviation NAV band, meaning that in theory at least FM broadcasts could interfere with existing VOR receivers - hence it became a requirement for IFR in controlled airspace to have (expensive) "FM Immune" equipment fitted.
Uk 5G upper frequencies are between 3.4 and 3.6 MHz. In Europe up to 3.8, whereas US goes higher. As I understand it some of the older radar altimeters can be quite basic.
Some planes also use it for several systems. It's a problem if affected.
It's not simple to test. 5G base stations are clever and can power down or up depending on demand. What is safe now, might not be in 5 minutes. They can also point their beam within certain limits at where the demand is needed.
FCC and FAA = two heavyweights at loggerheads. Interesting times.

The problems are in the >3.7 GHz band apparently. It's not just older systems either: it can affect the 787's auto deceleration system. Some planes also use it for several systems. It's a problem if affected.
