So when has this actually happened? There is a roughly zero percent chance that on any given flight, instructions to disable your phones are followed 100%. So, I think it's reasonable to suggest that literally every commercial flight flown in the past 15-ish years has done so with some device onboard that isn't in airplane mode.

Given that - why aren't airplanes constantly falling out of the sky? If this is the situation on every single flight, why isn't what you are suggesting actually happening?

edit: a downvote isn't exactly an answer, and I think it's a fair question. If the assertion is that cell phones etc cause serious problems for aircraft operations, then why are we not seeing it actually happen? Or are we saying that everyone on the flight is, in fact, turning every single electronic device they own off, every time, every device, for every person?

What I meant is that we are not talking about absolutes here. There will be some cell phones turned on, sure, but the less there is, the less likely it is to become a problem.

And one of the reasons airplanes are not constantly falling out of the sky is that there are thousands of little rules and safety considerations at every level. Software, hardware, pilot training, ATC, and some of them affect passengers directly. For example one not so obvious rule is that the cabin lights are turned off at night during landing, the reason is to make sure the eyes of passengers are accommodated to a dark environment in case of an evacuation. Rules related to electronic devices are in that category.

Rules are much less stringent on general aviation, but general aviation is also much less safe than commercial aviation. Cessnas don't fall out of the sky constantly but they do it more often than Boeings. The ratio is about the same as motorbikes vs cars.

I repeat, cell phones won't make planes fall out of the sky by themselves! But if the plane is already in the unlikely situation where it is about to fall out of the sky, everyone needs to be fully alert to respond to the situation, and the authorities concluded that it is better without beeping cell phones. Has it saved lives? We don't know, but if we waited for someone to die to implement safety policies, we would have a lot of dead people.

The rules may change, in fact they are changing and cell phones are allowed in some flights, but please follow the damn rules, there are here for a reason even if it may not be obvious. Flying is intrinsically dangerous: deadly speeds, deadly heights and deadly outdoor conditions. And yet commercial aviation is one of the safest means of transportation, the likes of the FAA and EASA are doing at least some things right.

And on a more personal, subjective note: I think it is a good thing to disconnect once in a while.

Funny how people without actual first hand experience with the issue defiantly ignore then attempt to refute every point you made.

A lot of people are ignorant of spectrum allocation, and sideband interference. Twenty years ago I had an old Samsung flip phone (2G/3G). I could tell every time a text came in when I was sitting at my computer, because the speakers would let loose with a tell-tale 'bzzzt bzzzt bzzzt' before the phone could finish handling it and displaying that I had a text. The handshake with the tower would be picked up somewhere in the audio path.

OK so here's my first-hand experience. In the 20+ years that personal cell phones have been commonplace, zero flights have experienced an accident as a result of that cell phone use. The FAA has also walked back the ban on use of personal electronic devices.

I appreciate that you feel strongly about this, but the world has done the experiment millions of times over a couple decades. We do not have to wonder about the outcome, the work was already done. Nothing happened.

So, neither reality nor the current stance of the FAA are in alignment with your assertion. "Funny how people..." indeed.
