Wiring in a big airplane is a lot of weight. I don't know exactly how much, but copper is pretty heavy. Airplanes are going to go wireless. It's already in the works. Maybe that's what they're worried about. Coming from me, that's only a guess.

Here's what I don't get....
The FAA continuously fly's around the country re-certifying ILS approaches. It's done at every airport that has an ILS approach. It would be a simple matter to set up approach scenarios that intentionally targets 5g emitters.... someone can correct me, but I believe there's enough on-line now that we could have a definitive answer within a 6mo. test period. I'm curious as to why this hasn't already been done... or if it has, why haven't they given a definitive answer... does it interfere or not?
Just guessing here ,Bare with me if it is wrong
It can be a situation of FAA Implementing ... " There is a New sheriff in Town "
More than a Technical problem ..
Establishing Authority for FAA ..perhaps forcing firings at places they don't think are Cooperating

Used to be a plane flew over and your automatic garage door would open. 5G may attack the ATM system, the 'Football' carried by the President's Team, and who knows what else? I think I will stay put here on earth, wait and see what happens.

I believe the radar altimeter involved here are part of the auto landing system on some of the larger jets. There is a guard band between the frequencies the airlines are using and the cellular phone companies frequencies. The worry is is that the much more powerful signal from the cell towers will swamp the input circuits of the radar altimeters even though they are operating on different frequencies. As several pointed out here the FAA is more concerned about could than will. I've only flown one plane with a radar altimeter and shot a lot of approaches in that plane during my instrument training. I have to say it's something that I didn't pay a whole lot of attention to and found it more of a distraction on approaches. I think the only time this will be a factor is an extremely I repeat extremely bad weather when the extra 50 ft that the auto landing can get with radar altimeter is involved. Course the bad news is that's exactly the time that you want the damn thing to work. Dark stormy night on approach to Idlewild low on fuel after a trans Atlantic flight is a hell of a time to find out the egg heads are wrong.
The big problem with GSM was hearing aids would squeal like pigs near them.
And remember the stickers on microwave ovens about staying away from them if you had a pacemaker.
Just saying. Nothing new under the Sun
I can't imagine how an airline can compete without CAT III Autoland. I was a CAT III autoland technician going back to the L1011. I also can't imagine this hasn't been tested again and again and again. Also, pilots and flight attendants don't generally concern themselves with turning off their phone except for preserving the battery.
I think staying away from a microwave is always a good idea, especially if you have eyeballs. I practice moving away every time I turn it on.
Really? I defeated the door switch and use it to warm my hands after a cold ride.
Just kidding Karen.
The big difference is 5g transmitters emit multitudes more power near the frequencies that the altimeter uses than anything else has . They worry is at some random time when conditions are at CAT III minimums that everything turns to S#@$ because of a very rare interference problem.
I loved flying on the L-1011. I wish the slug out would have been between Lockheed and Boeing instead of Douglass and Boeing.
I think the 5g is a secret device to shut off all those pesky internal combustion engines when the time comes. 2030 ?
Just Kidding.

Attempting to boil an egg in its shell in a m/wave does not end well.
Recall when a friend got their first Microwave, tried cooking an egg and it looked perfect when it came out of the oven. Then when he touched the yoke with a fork to try it, it literally exploded! Yoke had turned to dry powder!
A waitress friend of mine did something similar, a customer complained about his sunny side up eggs being cold, so she took them back and put them in the microwave, they held together just long enough for her to set them down in front of the guy before the yolks popped and splattered the guys shirt! He wasn’t happy!
Another late-to-the-party response.
Any hams in here remember this?
Remember 30-some years ago when airlines wanted passengers to turn off their radios and such? Seems silly, right? A radio only receives, right?
Overly simplified here, the majority of receiving equipment uses the superheterodyne design, where an internal oscillator's output is mixed with the received signal, and the resulting "beat frequency", also known as the intermediate frequency (IF) is demodulated to get the audio.
To get the desired 10.7mhz IF, the internal oscillator needs to be 10.7mhz lower, or higher. The FM band is about 10mhz above the aviation navigation band (VOR and Localizer). Some internal oscillators in cheap import radios would spew their unshielded emissions, interfering with nav instruments. In the general aviation (GA) world, some folks would install auto radios in the panel, exasperating the issue.
Bottom line, a cheap and poorly designed receiver can spew unwanted emissions into a neighboring band.
And, strong radiated signals can overload another receiver's input, and mix section...

| Big Telecom has a New Years' resolution: 2022 is the year when, finally, finally, after much fanfare, delay, and rethinking, it executes a proper roll-out of 5G mobile service. And they’re willing to do it by any means necessary — even if it means defying the aviation industry and the US Federal Government. | ||||||||
| Infrequent Proposal | ||||||||
| On Friday, the FAA and US Transportation Secretary Pete Buttigieg sent a letter to AT&T and Verizon requesting a two-week delay of the planned January 5th launch of C-band spectrum 5G wireless services, which operate on a frequency that may interfere with airplanes altitude-sensing radar altimeters. By Sunday, AT&T CEO John Stankey and Verizon's Hans Vestburg penned a letter in return. Their response? A resounding “no.” Amid the spat, both industries contend with high stakes: | ||||||||

| The French Concession: The telecom CEOs, however, did offer one point of compromise, saying they would adopt “exclusion zones” near major airports for six months, a model that’s proven successful near French airports. Me again; Even the slight chance of smooshing an airliner full of people into a runway on a foggy night seems like a good reason to be cautious. Even with the im-portance of everyone, having everything, streamed, all the time................ |
That is a worthy thought, but some people like those laser lights that blind pilots, and now they have a new tool to try. Results won't be long coming in.
An ILS or GPS approach to minimums isn't a "single point fail" scenario. Either would require multiple failures and a very inattentive flight crew. If it happens, a smooshed airliner won't be the fault of 5g.
Well here we go.
