A lot of comments are saying flights in the EU are still asking passengers to put their cell phones in airplane mode. That may be true but as of over a year ago the airlines are no longer required to say that. In 2022 they ruled that all member nations must make 5G available to airplanes by June 30, 2023.

Airline pilot here, the amount of times I've seen a message mid flight saying "welcome to X country" as you get random signal when you've forgotten to use flight mode. I'm still alive so far. The frequency thing is real though, Boeing had a notice out for a long time about 5G and rad alt interference, but it's now fixed.
I've never heard of an air crash investigation that concluded that the reason for the crash was that Karen in the back forgot to turn on airplane mode.
Don’t ever be someone in charge mate, this reasoning has caused many people lost their lives in the past 😂. Like someone warns but because no casualties, they never prevented that until there’s casualties
I'm just glad that they've moved on from saying that any radio frequency has the potential to interfere. I remember when Airplane Mode turned off Wi-Fi and Bluetooth too. I think I remember when you couldn't turn them back on without disabling Airplane Mode.
@@_apsis maybe it's an Android/iPhone thing, but it's been some years since my phone has turned off all radio when switching on Airplane Mode, which makes sense since you're allowed to use Bluetooth and they provide WiFi on the plane.
Samsung A32 airplane mode will turn off BT and Wifi as well as cell signal. However, now they can be turned back on individually while remaining in Airplane mode.
Exactly treue. I had many domestic flights in Türkiye and International flights to North and Central Europe with Turkish Airlines and they are always announcing turn on plane mod for devices 😂😂
As Mark said, In Europe and here in UK we have more of a buffer between all licensed frequency bands. For example... For 5G we used 3.4ghz to [& including] 3.8ghz. the rest is there & available. Then 4.2ghz for airoplanes. This is why American airports don't want 5G on the 3ghz band. I also heard it's more to do with the navigation system, phones aren't just receivers, but transmitters too.
And no harmonics overlap either. The real reason has to do with tower roaming in the cellular network. Moving too fast and much reach overwhelms older cellar networks.
EXACTLY! I work in radio as a broadcast technician and i’m so tired of regulations made by politicians who don’t know what the difference is between ERP and TPO
Radar/radio altimeters are great for situational awareness but pilots are also trained on how to use barometric altitude to determine distance from the ground. All instrument approach procedure charts have both barometric and radio altimeter minima.
I heard an interview with a senior authority in a europian airline. They still want your devices in flight safe mode because they dont want people yapping away on their phones during take off and landing
The requirement actually began with the FCC being concerned about overloading cell towers due to the reduced obstruction (trees, terrain, buildings) from devices passing above them.
Imagine relying on hundreds of people to do something just so it might not affect one function of an aircraft. It's almost as if analog instruments aren't a thing.
One of the many problems in life where the answer is "just move to Europe"... In all seriousness, I don't think this is accurate. The FAA doesn't restrict cell phone usage due to disruption of the planes, but its the FCC who originally passed restrictions to prevent disruption to the cell towers on the ground. 200 cell phones connecting to dozens of towers could be a problem
His frequency ranges have zero basis in reality. Cell phone never used above 3.8GHz until a couple years ago and they waited until after they worked out all possible interference issues.
When I studied telecommunications I learned that the biggest problem is, if your device manages to connect to a tower. The handover between towers cannot handle the speed of which you are traveling. It's almost as if you're in multiple zones at once. That confuses the network. Planes themselves are fine.
@@kubakielbasa5987 they literally tell you you can turn your phones back on every flight I’ve been on everyone is using their phones, I think we would have issues if that was true and I don’t think they would say you can turn your phone back on once in air, have you been flying?
Yup. This video is also not accurate, phones can go onto different channels on the same frequency to now collide with each other, they also have technology to make sure no other signal is disturbed. That’s why we have FCC Regulations and testing.
As a German, yes they do say on every flight to put all devices in airplane mode but I always wondered why exactly that was a rule so thanks for explaining ❤
Not putting your cell phone on airplane mode drains your battery because it’s constantly searching for a connection. But also people talking on the phone during the safety demo distracts you and the people around you when you should be paying attention
Landing in dense Scottish fog in a small prop plane ... They actually asked us a second time before landing to ensure our phones were in airplane mode as there was zero visibility on the ground.
Also there’s the fact that you won’t have any signal anyways… most cell towers are aimed downward toward the ground… where the people are. So I’ve heard part of the reason airlines do this is so people aren’t constantly complaining about dead phone batteries, from your phone frantically roaming the entire flight
True, mostly. I've gotten weird little pockets of signal at 30,000ft during the middle of flights before. But for the most part it's just not happening. Better off either turning the cell transmission off and/or using their satellite Wifi if it's available.
As far as I know, the only time where radio altimeter interference would be an issue is on an instrument approach down to minimums. Even then, you don't need radio altitude unless you're doing a Cat 2 or 3 ILS down to the ground. Otherwise you still have GPS and Baro altitude which all instrument rated pilots are trained on, myself included. I'm not an airline pilot though, so the radio alt might be necessary for other ops that I'm not aware of yet.
The main problem is that the phones end up communicating with cell networks over much longer distances than normal and that can cause issues with the cell phone networks. The aircraft are mostly not bothered. But many planes these days have microcell service which puts the phones in very low power transmitter mode which means the signal doesn't go nearly so far.
Also, the cell phones jam the towers because they miss their designated timing windows if they travel too fast. And a broader range of towers to attempt to connect to exacerbates the problem. It's a FCC regulation, not just FAA.
To save battery while in the air, put your phone in airplane mode. It’s using a lot of juice trying to connect with towers far away. The farther from the tower, the more juice your phone sends to its transmitter to find someone to connect with.
It's radio altimeter. And generally, planes don't need precise AGL readings when heading into runways. There are also barometric altimeters for MSL readings
This short is not true. Some elements are accurate but I’d classify this as misinformation. Most likely a ChatGPT question and answer converted into a video.
That's because all the reasons are made up or exaggerated. There are millions of cellphones sending signals all around cities and airports, and there are backup analog systems for altimeter as well as radio triangulation. I think these people just like to impress passengers with how important their safety is and push their own services.
"Or alternatively, just move to Paris." Okay, okay, I'll put the phone in airplane mode, I'll put whatever you want in airplane mode, just please, PLEASE, don't make me move to Paris.
I'm pretty sure thos rule is just i relic of early misunderstanding of cell networks. The FCC was worried early on that a bunch of flying cell phones would overrim the cell network and overnurden towers, but cell tower antennas are directed downward which means you cant even receive the signals at altitude anyway. Airplane mode is not a necessary thing other than to save battery life.
Why don't they just tell us information in a nice graphic like Mark has done here? I think it'd be much more effective in compelling compliance than just dropping the info without any context.
If I remember right. Most portable devices that have transmit function are limited in how much power they can transmit with, and as the warning says. Must accept any and all interference. If any phone has enough power to actively interfere with any radar set, I'd say you need a better radar. Not only that, they have the authority to get the frequency changed. And it would still be easier and more effective to change the radar.
The airplane-mode instructions are a service to the FCC not FAA. A cell phone flying through sky, switching towers fast, is taxing for the telecom systems
This is the correct answer. Rober is rarely wrong, and I’m not saying the frequency facts here are incorrect but that’s not why passengers are asked to turn on airplane mode. Zero danger to the plane!
you think the altimeter won't be able to pick out it's own massively stronger reflected signal over the wimpy phone antennas, at barely 1000m or less? I highly doubt there would be a problem.
i flew out of the country twice last month (4 flights total because return flights too) and i wondered this basically each time so seeing this video now is just amazingly perfect timing
Airplanes ask passengers to switch their devices to airplane mode to prevent electronic interference with the aircraft's communication and navigation systems. Many electronic devices, such as smartphones, transmit signals that can potentially interfere with the sensitive equipment on board. While the risk of causing significant issues is low, it’s better to be cautious. Airplane mode disables wireless functions like cellular service, Wi-Fi, and Bluetooth, ensuring that devices don't emit signals that could interfere with the plane's systems. Additionally, airplane mode helps ensure that passengers remain focused and that there are fewer distractions during the flight.
Shielded and twisted pair cabling seems to have worked well in large Telecommunications networks plus other electronic tricks. The international satellite network uses guard bands between channels and you only need a few kHz between them. A few kHz in a GHz band is a 1/100,000th of separation needed.
The real reason you should use airplane mode is because cell towers point their signal down, so its a lot harder to get a signal. On top of that, if youre flying at 4-500mph, youre going to be going in and out of range of towers very quickly. So your phone is going to strengthen its radio signal to try harder to connect to a tower. Its just going to drain your battery super fast.
I can’t be the only one who has a massive crush on Mark Rober. Seriously, for like the past 10 years I’ve watched his videos with heart-aching longing. 💛😩
Its basically also to avoid damaging the infrastructure with the fast movement of a plane and its position an airplane full of phones trying to connect to towers beneath can cause quite the havoc on the towers on the ground.
Just turn your phone off. Give your brain a break. Take a nap, read a book, watch the in-flight movie and enjoy a cocktail. Disconnecting is wonderful.
As a glider pilot i can assure you that after 2000/3000 meters (6000/9000 ft) the radio cells are not anymore receivable, so keeping the cell phone radio is useless first 3/4 minutes after takeoff, when normally you are already at 5000mt (15000ft)
Imagine being on a full flight with everyone chatting away about BS. Its bad enough in a doctors office. Being trapped in an airplane with a lot of people on their phones sounds like a nightmare.

As a french they ask to put our phone in airplane mode
But do you live in paris?
you gotta stay near the Eiffel tower
I too ask every French to go into airplane mode.
@@DC7xxxxxx No
I'm sorry.
Airplanes ask passengers to switch their devices to airplane mode to prevent electronic interference with the aircraft's communication and navigation systems. Many electronic devices, such as smartphones, transmit signals that can potentially interfere with the sensitive equipment on board. While the risk of causing significant issues is low, it’s better to be cautious. Airplane mode disables wireless functions like cellular service, Wi-Fi, and Bluetooth, ensuring that devices don't emit signals that could interfere with the plane's systems. Additionally, airplane mode helps ensure that passengers remain focused and that there are fewer distractions during the flight.
As an Engineering student I was taught you're moving so fast that you'll confuse the network, but the RF interference issue is also very valid.
What kind of school teaches that🤔
Shielded and twisted pair cabling seems to have worked well in large Telecommunications networks plus other electronic tricks. The international satellite network uses guard bands between channels and you only need a few kHz between them. A few kHz in a GHz band is a 1/100,000th of separation needed.
Every single flight I’ve been the last decade has told me to use airplane mode… /swede
What will win? A Chinese phone for 100 dollars or a plane for several million
a 1cent screwdriver bro XD
Here in the uk we still ask passengers to ensure that devices are switched OFF when doing an autoland but otherwise they can be on any other time.
Дуров тоже захотел переехать в Париж....
The real reason you should use airplane mode is because cell towers point their signal down, so its a lot harder to get a signal. On top of that, if youre flying at 4-500mph, youre going to be going in and out of range of towers very quickly. So your phone is going to strengthen its radio signal to try harder to connect to a tower.
Its just going to drain your battery super fast.
If any system on an aircraft can be disrupted by a few cell phones then the engineers were not doing their job.
I can’t be the only one who has a massive crush on Mark Rober. Seriously, for like the past 10 years I’ve watched his videos with heart-aching longing. 💛😩
Airplane mode saves you from ridiculous roaming bills
Nope.
Even without interference, the equipment still didn’t help Ryanair land…
This felt like a Vsauce video
So real
Its basically also to avoid damaging the infrastructure with the fast movement of a plane and its position an airplane full of phones trying to connect to towers beneath can cause quite the havoc on the towers on the ground.
Airlines in france ALWAYS asked us to turn phones off or more recently to put them in flight mode
Crazy how there is a tiny chance that a tiny phone can interfere with a plane that costs millions 💀
Well now a days phones are more like a tablet
There is absolutely zero chance.
Just turn your phone off. Give your brain a break. Take a nap, read a book, watch the in-flight movie and enjoy a cocktail. Disconnecting is wonderful.
Completely agree
As a glider pilot i can assure you that after 2000/3000 meters (6000/9000 ft) the radio cells are not anymore receivable, so keeping the cell phone radio is useless first 3/4 minutes after takeoff, when normally you are already at 5000mt (15000ft)
Imagine being on a full flight with everyone chatting away about BS. Its bad enough in a doctors office. Being trapped in an airplane with a lot of people on their phones sounds like a nightmare.
I love how he casually tells us to move to the pickpocket capital of the world.
Oh… I was playing chess for 60 minutes straight online without airplane mode.
Thank you for explaining maybe people will now understand
Fun fact: I’ve never set my phone to airplane mode. 😐
That flight attendant was a 10/10
Bro
Ngl tho lol
10/10 ❌
way too much makeup ✔️
I don't think I have ever once put any of my electronics in airplane mode.
Why exactly?
