vudukungfu: cell phone user = asshole in my bookI actually carry a book.
italie: You may be cool with flying by the seat of your pants, but the FAA has other beliefs on the matter.
Stone Meadow: italie: You may be cool with flying by the seat of your pants, but the FAA has other beliefs on the matter.On the contrary, for well over a decade the FAA have been under unrelenting pressure to drop their absurd prohibitions against consumer electronics in flight, and only begrudgingly edging forward. NONE of which can be traced to any technologically defensible safety concerns. And moreover, won't be...since aircrew have been free to use them since the late 90's.And now? They've thrown in the towel for everything except cell phone use in flight...and why? Because they know that cell phone use if not a safety threat beyond the entirely understandable desire to throttle the douchebag next to you who's yelling into his plastic prosthesis.So give it up. If there were technological reasons to prohibit electronics use in flight, the FAA would stick to their guns. But they aren't, so we know there aren't any reasons beyond "Because we say so."
James10952001: I don't talk on my phone in public unless I have to and then I try notto talk too loud. I'm not an asshole though.
Stone Meadow: James10952001: I don't talk on my phone in public unless I have to and then I try notto talk too loud. I'm not an asshole though.I understand...and was referring (by implication) to the fear we all share of those inconsiderates who WILL talk too loudly and too long in flight.
italie: The FAA can now reasonably say "Your ipad will not cause a fiery death".
Stone Meadow: There are so many generators, high- and low-frequency alternating and direct current devices on airliners that the leakage of UL-listed consumer electronics is simply a non-issue from any kind of safety-of-flight perspective.

italie: Bottom line is there is no farking conspiracy. There was a discernible risk with cellphones. It's getting better, it's more thoroughly tested, instruments are better protected. These are the reasons that the FAA is loosening the reigns a bit.
heili skrimsli: italie: The FAA can now reasonably say "Your ipad will not cause a fiery death".if your iPad was ever thought potentially able to cause a firey death, you'd have been allowed to bring it on board just as much as you'd have been allowed to bring dynamite.
italie: I've seen those in the NTRS reports,
heili skrimsli: italie: I've seen those in the NTRS reports,Given that GPS is a digital signal, interference that damaged the signal would mean that the GPS would not function.There's no damn way to interfere with that signal and just cause a '30 degree error in course' in the way that it has been described.
insano: "spmkk: Enemabag Jones: "Invent keychain sized cell phone jammers if this gets approved.It would not have have to be huge, just look like a GM car remote and would only have to work in bursts. Just like that keychain tv remote thing."Yes, because your right to not be subjected to (gasp!) nearby conversation in a semi-public place supersedes someone else's right to stay connected with their work team or speak to their loved ones.Speaking of things that are not rights."
italie: Unless you designed that system, there is no way you can make that statement. Doing so is just irresponsible. Digital signals are much less prone to certain types of interference, but by no means immune. (Adjacent band interference would be a prime example here.)

Digital signals are much less prone to certain types of interference, but by no means immune. (Adjacent band interference would be a prime example here.)I have more than enough expertise in digital electronics and wireless digital communication to be certain that the suggestion that this was caused by some portable DVD player is utter bullshiat.When you break digital packets transmitted via any medium (including radio waves through air) you don't merely change the data inside the packet, you destroy the packet. There's no way that a portable DVD player receives valid GPS data packets, alters the data, reforms the packets, and then transmits them to a GPS receiver.It's absurd to even suggest.
b0rscht: A fricking switching power supply will spit out crap across the entire AM/MW band. Here's a picture of me after finding the culprit causing S9+ interference on some of my favorite ham bands:[googledrive.com image 800x600]Granted, you're not going to find switching power supplies in the cabin. The point is, it's equipment that's faulty, operating outside of its designed parameters, that should be of concern, in my opinion, not cell phones/laptops operating within their designed parameters.
