    Although they are clearly electronic devices, rarely does a flight attendant ask a passenger to turn one of these units off.

    It really depends on the flight attendant. I've had them demand that I turn mine off (Delta was very strict, as I recall), and others have said nothing at all. I've pretty much solved the problem by putting a piece of black tape over the LED that announces "HEY! I'm ON!". It's an obvious piece of tape, but as long as they don't see the LED they leave me alone.

    If this ruling is applied by the CAA in the UK, I will gain about 50 hours a year of time I can spend reading. That is a massive win.

    If you went to bed just ten minutes later each evening, you'd gain more than 60 hours of reading time each year. If you read paper books instead of abandoning that simple technology, you'd still have your 50 hours.

    You're incorrect for counting the 10 minutes "to the terminal" after landing. You can turn on your cell phone as soon as you land, at least in the US, and I seem to remember that announcement on non-US flights I've been on. (But that's not an Ebook like I'm restricting myself to using!) You can read ebooks on most smart phones.

    Sorry, I'm used to VHF/UHF voice operation on 2-meter - a .004 difference isn't all that bad and would still be entirely functional

    That's odd. When someone tries to use my 2m repeater and they're that far off frequency, they are always distorted and usually unintelligible. When you're using a 4kHz deviation system, that means your entire signal is on one side of the passband at the receiver, and unless the receiver is really really sloppy, you're outside the passband for a large part of that signal. You're 27ppm off frequency at 144MHz. That's huge. 5ppm is considered large these days, and 2ppm is standard practice (at least for LMR).

    And don't go to Europe, they're starting to use narrowband, and 4kHz at 144MHz would be outrageous.

    On a radio with 5kHz steps, being 4kHz off means you're closer to next frequency up or down than you are to the one you are trying to work, and you probably ought to deliberately detune your radio to be closer to on-frequency. That's kinda exactly what someone who is dealing with a doppler shift has to do.

    Installation AND operation. Maybe clipping onto the chassis is "installation", but holding the radio in my hand next to the window isn't. Were it "installation or operation", you'd be right.

    So, as long as you get permission from the pilot in command, go for it. Just like before.

    No, actually, not like before. The pilot in command doesn't have the authority to approve use of amateur radios on board "an aircraft operated by a holder of an air carrier operating certificate or an operating certificate". That's 91.21(c) of the federal aviation regulations, which just happens to be the rule that needs to be amended for the airlines to allow PED use in the first place.

    It's not the airlines, it is the FAA. Preflight briefings are mandatory. Here is the rule. It is in a section that deals with larger aircraft, so the private pilot who is taking his friends up for a sightseeing tour isn't REQUIRED to follow that reg, but he's a fool if he doesn't do a briefing that includes how to open the door, keep your seatbelt on at all times, don't touch anything, and "that noise you are going to hear when we land (bzzzzzz - stall warning horn) is normal, so don't freak out."

    6. Properly stow heavier devices under seats or in the overhead bins during takeoff and landing. These items could impede evacuation of an aircraft or may injure you or someone else in the event of turbulence or an accident. My bad, I confused "stow" with "turn off." Because having it turned on does so much good if it's stowed.

    "Heavier devices". The MP3 player "stowed" in my pocket does me a considerable amount of good. The noise cancelling headphones do me an even greater amount of good when stowed on my head in the 'on' position.

    This is no change. There was never a prohibition against using wi-fi or bluetooth.

    You are wrong.

    I've flown several airline which offer w-fi during flights in the past decade, usually with a hefty fee.

    This is a very specific exception to the rule against radio transmitters on board an aircraft. Except for the relatively recent addition of on-board wi-fi services, wi-fi and bluetooth have been prohibited while in flight.

    You can also continue to use short-range Bluetooth accessories, like wireless keyboards.

    The airline you fly has been letting you bend the rules. The ones I fly are quite explicit in saying "you may NOT use short range".

    I read it, dingleberry.

    Being insulting doesn't make you right, it only shows that you are overly sensitive when you get caught misreading something simple.

    The only real difference is not having to turn things off during the 10-15 minutes of takeoff and landing.

    Plus being able to use wifi and bluetooth in general, and many other kinds of radio receivers. This change would legalize all the people who sneak GPS receivers on board to follow their flight. It would even legalize the use of scanners to listen to ATC. And many people would consider a change that removes the requirement to turn off noise cancelling headsets to be a major change to the rules since it was such a patently absurd side-effect of a relatively simple rule. It was, in fact, a detriment to safety, since people who were wearing noise cancellers plugged into the aircraft audio system were about the only ones who could hear any of the announcement made during takeoff -- like "assume crash positions".

    I'm pretty sure radios capable of transmission are still a no-no.

    It does help if you read the actual article before you say something like that. The FAA is rather specific about not using cell phones, and just as explicit that other transmitters (like wifi and bluetooth) are perfectly acceptable. And the only reason they are explicit about cell phones is not because of the transmitter technology, but the FCC frequency allocations for some of the frequencies involved are land mobile only, not air mobile.

    The US military has come up with a system called GIIEP (pronounced "jeep") that allows airborne cellular data transfer in real time, using commercial cellular data system. They've managed to get a commercial cell modem manufacturer to disable the two (IIRC) bands that are land mobile only so only the frequencies that are legal for airborne use are available. Those "cell phones" would be usable from the air, except that it is too hard for anyone to know which ones are and are not legal there so it is easier to say "no" than "ok if...".

    Ok. My bad.

    And I'm confused about some of your other comments... AFAIK there are many products (expensive, mind you) that can listen in on cellular frequencies,

    Yes, there are. That's why I said "certain kinds of radios". Those the public would be most likely to buy are the main target. Scanners, for example. Some "communications receivers" can receive cell frequencies, but the dealer may limit purchase to authorized government agencies (this one, for example.) The key words to look for are "cellular blocked".

    The FCC could not simply ban every radio capable of receiving cell signals. That would have made it illegal for HP to sell the CDMA service monitor I now own. Or almost any service monitor for that matter. That would have made some TVs illegal for sale, since they reused some of the upper UHF TV spectrum for cell. They went after the low hanging fruit, to prove to the people who were ignorant of how radio works that the FCC cares about their privacy and did something.

    It is long past the time to remove that idiotic regulation. The cell carriers have solved the problem of casual interception, and they cannot solve the problem of deliberate eavesdroppers.

    No, it's rules that they don't understand that they think are silly. And evidence shows that many people who use cell phones believe there is some magic involved that carries their voice to the intended recipient. That's why back in the 90's a vocal group of idiots managed to get laws enacted to insure their privacy while using analog CDMA cell phones. After all, it was a CELL PHONE and they had every reason to expect privacy in their conversation, even though they were using RADIO to send their VOICE over the public's airwaves. Thus it became illegal, and remains illegal to this day, for the sale or import of certain kinds of radios that can receive frequencies allocated to cellular telephone services.

    Anyway, "airplane mode" is still useful. Probably should be called "non-emission mode" or something though.

    The only non-emission mode for a cellphone is "battery removed". Otherwise, the CPU is still running and still using square-wave clock signals and still emitting something. Even if it just wakes up once a second to check the "on/off" button to see if it should turn all the way back on.

    "Airplane mode" is "radios off", because (most) radios have deliberate oscillators in their receive section that can easily leak and act like transmitters, and cell/wifi/bt are all deliberate transmitters to start with.
