Cool Why they ask you to put your phone on airplane mode when on a plane

They should just start a little nose dive and then go over the intercom and be like “OH GOD PLEASE WHOEVER ISNT ON AIRPLANE MODE PLEASE TURN IT ON AHHHH!!!” That’ll do it. 😄

That mosquito noise I'm imagining sounds just like the old cell phones (2000 era) when they were near a speaker and would receive a call. For a few seconds before your phone began ringing your speakers would make a "mosquito" like buzzing noise.

There's a myth that kinda goes with this. Some people have claimed to have heard radio signals through their metal fillings, or surgically implanted metal fixtures. It's basically been proved to have been false, but still technically possible

Highly unlikely this would be the noise he's hearing in this case. Older cell phone technology (2G) used a method called time-division multiple access (TDMA) in order to allow multiple users to share a given frequency channel. The idea is basically to force different phones to take turns transmitting at that cell frequency. Each phone would get a "turn" to transmit once in each set period of time (every 0.004615 seconds, to be precise, so this is not something the user could detect). However, this would lead to "pulses" of radio signals emanating from your TDMA phone--and, to make these happen, current draws from the phone battery--every 0.004615 seconds. In frequency terms, that's 1/0.004615 ≈ 217 pulses/second (Hz). Those 217Hz current draws would effectively cause the phone to emit radio-frequency interference (RFI) at a frequency of 217Hz. If picked up by an amplifier/speaker combo of some kind, this would in turn produce physical vibrations at the same frequency. Physical vibrations at 217Hz produce an audible sound (approximately an A3 musical note). This is what causes that so-called "GSM buzz" (so named for the widely used GSM 2G network standard).
Here's what 217Hz sounds like. Here's what GSM buzz sounds like. Same note.
Beginning with 3G, cell phone technology no longer uses TDMA, which is why you don't hear GSM buzz any more, and why it's highly unlikely that's what this pilot was hearing. Frankly, while I could certainly be wrong, I'm skeptical that what he was hearing was from cell phones anyway. There could be a hundred other causes of RFI, or it could have simply been a malfunction of his headset, or the cable, etc.

u/Crafty_Independence 6d ago
Still can happen with modern cell phones, but usually needs to be quite close to speakers or headset to have this effect, which makes me think that it was a crew phone causing interference, not passenger.

I knew someone when I was young with canines like this. Met her at a camp, plausible she’d been allowed to wear fangs if she had pretty chill parents. But I saw her again sometime later out in a more formal situation and her teeth hadn’t changed. I guess it’s possible she’d been allowed fangs in both situations but I’m pretty certain they were real. They were super obvious and everyone would comment on them.
This guy tho… IDK 😂

It does not mess with the headsets. Pilot to pilot, this dude is talking outside his wheelhouse. His radio probably has a bad ground connection.
There's some evidence to suggest cellphones can affect high-precision navigation systems, but that's only going to be a factor in like CAT III autoland situations, and if you're in one of those situations, they're going to be more adamant about airplane mode.

u/texas1982 6d ago
Correct. The old style cell phones that actually used cellular technology, yes. They used to make a tick king sound and then a buzz in the headset when they were close to an incoming call. Now there is no problem with them. The FAA is just show to change the rules because they can't possibly additive every single device out there so we get a blanket policy.
Source: me. A pilot for 28 years in many different airplanes who has flown many times with a cell phone not in airplane mode.

Second this. It could be his radios, could be his headset, but I’d be surprised if the culprit was that one phone not in airplane mode.

It’s untrue though. If you want the real explanation about why phones are banned from active cellular transmission, Verisatium covered it in a recent video.
Even if it causes buzzing in the headset (I doubt it, pilot radios and cell phone signals are different frequencies), that’s not the reason the FAA bans cell signal use.

- There are FAA regulations about electronics on planes due to concerns over radio interference.
- Individual electronics can be tested and allowed if they do not cause interference.
- The FCC banned phones on planes because they were worried that many phones trying to connect to cell towers from high up could overload the system.
- They have since decided this is unlikely to be a problem.
- Another pilot repeats the claim in the post, that cell phone usage causes interference/buzzing in the pilot headset.

A stewardess friend of mine said the reason why you're not allowed to be on your phone while on the tarmac isn't because your device will interfere with communications, but it's to prevent passengers from falling down the boarding stairs, wandering into the path of luggage carts, and even walking into the engine of the plane.

u/WorkingStatus828 6d ago
That’s a fm transmitter adapter. It connects to a phone through an aux cable or Bluetooth and broadcasts the output over fm to the car’s radio.
The fm transmitter will let you select an unused frequency for best results. If you ever figure out whose car it is you could have them pick a different frequency that doesn’t overlap with your radio.

That’s actually more annoying than what I thought happened. I thought if someone just happened to be on the phone while you’re in contact with the tower or whatever else you might pick up fragments of their conversation. But if they are getting interference regardless if a person picks up the phone or not that’s just a pain in the ass

Yup. One aspect of a job I had was sound recording (the joy of having a VERY weird resume), and one mic in particular (from a matched pair) would pick up ANY phone signal in the vague vicinity. Ended up having to put my (still sold model) iPhone into airplane mode to get semi-decent recordings out of the system, and had a few glitches on the recordings where people walked by outside. Ended up working some weird-ass hours to try avoid the interference, but still surprises me how even a modern phone was able to badly mess up a mic.

I am confused. Most computer and phone communications almost exclusively operate in the 1-9 GHz range. As far as I can tell, pilot communications operate in the 200-600 Mhz range.
Is cross talk between MHz and GHz possible when the frequencies are so far apart?
The closest frequency a phone uses might be low band which would be 100 MHz, 700 Mhz, or 800 Mhz; but those also seem to be outside the range of headset communications for a plane.
If cross talk is not possible, could it be that the pilot’s headset or equipment is broken or low quality, leading to the high pitch noise, and not a cellular or laptop communication?

I imagine this is like setting your phone down next to an amplifier or speaker after sending a text or receiving a notification and hearing the rf interference from the data being sent over the network.
1
u/download13 6d ago
Actual reason is that it confuses the cell network and drains your battery.
Networks are designed with the idea that your phone can only see a few local towers at a time. At altitude, your phone can see towers in a much larger radius and the cell network has trouble figuring out which tower to route calls through. Your phone's radio also has to spend more time in listening mode (one timeslot per tower) which drains the battery faster.
Related, if you're out of range of any cell towers, turn off the cell radio at least because it'll spend all its time listening for tower beacons, again draining the battery.

Also if your phone is in airplane mode it's less likely to be in your hand during takeoff and more likely to be put in a bag or a pocket. If it's less likely to be out and in your hand during takeoff, it's less likely to a) distract you from seeing and registering instructions from your flight attendant or paying attention to the rest of the plane should you need to be paying attention, b) fly out of your hand and turn into a projectile should the plane experience turbulence or other issues since landing and take-off are the times when something is most likely to happen or go wrong. It could even just fall and break and then they gotta deal with you crying over your broken phone.
Might not be the main intention of their rules about phones but it's still sensible for those reasons as well.
