With regard to a previous comment about using commercial flights and having to turn the e-book reader off during takeoffs and landings, I can see how that might be an inconvenience of any of the e-readers vs actual paper. I'm not so sure that I agree with their policy of making us turn off all of our electronic devices. I'm pretty sure that those people with electronic watches do not turn off their watches during those flight phases. In fact, I would hazard to guess that most battery powered watches do not even have the provision to be turned off without removing the back of the watch and physically removing the battery. Some of the electronic watches are a bit more full featured than others and have calculators in them and I have even seen some that have cell phones in them. I think that we need a bit more real world common sense with respect to what might cause interference. If a calculator is not expected to interfere with the cockpit avionics, then something like the Kindle should not as long as it is possible to turn off the wireless features of it. Of course from a control standpoint, it is just easier to tell people to turn off their devices than to tell them to reconfigure them so that they are not broadcasting on any RF frequency.
Watches draw far less power from their battery than the devices the airlines get excited about. Draw less power, create less RF energy and lower signal levels. Keep in mind that the airlines are dealing with Part 121.306 of the FARs which says,
"
§ 121.306 Portable electronic devices.
(a) Except as provided in paragraph (b) of this section, no person may operate, nor may any operator or pilot in command of an aircraft allow the operation of, any portable electronic device on any U.S.-registered civil aircraft operating under this part.
(b) Paragraph (a) of this section does not apply to—
(1) Portable voice recorders;
(2) Hearing aids;
(3) Heart pacemakers;
(4) Electric shavers; or
(5) Any other portable electronic device that the part 119 certificate holder has determined will not cause interference with the navigation or communication system of the aircraft on which it is to be used.
(c) The determination required by paragraph (b)(5) of this section shall be made by that part 119 certificate holder operating the particular device to be used."
The airline has to make the determination as to which devices may be used. They are NOT going to evaluate each device on the market. And a Kindle looks like a tablet computer to someone who is in a hurry checking all seated passengers during their safety check. That and they don't want items like that unsecured during takeoff and landing. I think you are going to lose this discussion with an airline operator. It's not worth their time to do the investigation and they're quite satisfied with the status quo.
As to the actual EMC ramifications, suffice to say that the recent article in the Boston Globe saying that cell phone usage on airliners is safe according to a paper written by the IEEE EMC Society has drawn a strongly worded letter from the President of the Society (with input from several of us on the Board of Directors of the Society) taking exception to the article for a number of reasons (one of which is that the Society has written no such paper). And the papers cited in the article had portions taken out of context and the authors made no such claims. While cell phones put out stronger signals than the typical unintended emissions from a laptop or a Kindle, you get the idea. Please leave these determinations to those who are tasked with making them.
