The rules are entirely arbitrary, and have no basis in science. I have been told to turn off a GPS receiver that ran on two AA batteries for 12 hours. There is no possible way that you could affect the planes electronics with the power of two AA batteries. Especially not with electronics designed to be quiet enough not to interfere with the extremely weak GPS signals it must listen to.
The electronics on a plane must be horribly designed if they can be affected by any hand held electronic device.
From an IT standpoint, I think a single device obviously can’t cause any issues. No single phone or sig al emitter could, unless specifically designed for it. Now the next I don’t have as much confidence in, but I bet if even half or more use items, same deal. No big issue. If everyone at once decides or coincidentally all cause high emmisons, maybe that would be an issue.
However, how to you get everyone to understand that? You can’t say most should do it, or ask half to do it. Too many would assume others should do it instead of themselves. Bystander effect etc. If you instead have attendants choose, how to be fair and not piss people off? If it really is a low chance but something you may possibly be sued for, also why do so?
Smartest thing for a large company to do is just ban it outright. It might only have a 5% chance of failure if and only if a passengers use their phones incessantly, and it would still be safer to just ban it outright.
While the interference from one mobile device might be negligible, the combined interference from several devices could potentially disrupt the airplane’s communication and navigation systems. This is more of a concern during critical phases of flight, like takeoff and landing. Notice I said potentially. It is unlikely to occur, but since 70+% of all aviation accidents occur during takeoff and landing, they use an abundance of caution.

Is there any evidence of this ever actually happening?
