mdmania Posted February 12, 2007 Report Share Posted February 12, 2007 how can an MD affect the airplane controls, i never understood...My guess is that it might interfere with their digital tracking system or communication system, I don't exactly know what the name of it but sounds good to me. I hope that helps. Quote Link to comment Share on other sites More sharing options...
Sparky191 Posted February 12, 2007 Report Share Posted February 12, 2007 I was looking at this on a flight recently. Playback is prohibitied during take off and landing, you can playback ok during the flight. But recording on a Minidisc is prohibitied the entire flight.

raintheory Posted February 12, 2007 Report Share Posted February 12, 2007 My guess is that any sort of electromagnetic interference (created by just about any electronic device) can potentially interfere with radio communications (among other things, instrumentation, etc). Although why they would allow the use of these devices in flight and just not during takeoff/landing is beyond me. Quote Link to comment Share on other sites More sharing options...

That is based on my assumption again. Quote Link to comment Share on other sites More sharing options...
Sparky191 Posted February 12, 2007 Report Share Posted February 12, 2007 I don't think there's any proof of interference its a "just in case" scenario. Quote Link to comment Share on other sites More sharing options...
riotshield Posted February 12, 2007 Author Report Share Posted February 12, 2007 I don't think there's any proof of interference its a "just in case" scenario.i agree with that. it would be nice if we could find some scientific proof that indeed it doesn't really matteror maybe manufacture a "flight operation enabled" sticker.taking off and landing are so much more beautiful when u are listening to music Quote Link to comment Share on other sites More sharing options...
A440 Posted February 12, 2007 Report Share Posted February 12, 2007 My guess is that they make you turn off all electronic devices because they don't want to deal with exceptions--everyone turns off everything. What they seem most worried about is cell phones and GPS signals that can interfere with the plane's guidance system. Google found this subcommittee hearing on the subject--you have to use the cached copy because the original has moved. http://209.85.165.104/search?q=cache:8Jaks...-20-00memo.htmlSo they do believe that portable electronics affect navigational systems. Here's the official regulation, from this link:http://a257.g.akamaitech.net/7/257/2422/14...4cfr121.306.htmTITLE 14--AERONAUTICSAND SPACE CHAPTER I--FEDERAL AVIATION ADMINISTRATION, DEPARTMENT OF TRANSPORTATION (CONTINUED) PART 121--OPERATING REQUIREMENTS: DOMESTIC, FLAG, AND SUPPLEMENTAL OPERATIONS--Table of Contents Subpart K--Instrument and Equipment Requirements Sec. 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. © The determination required by paragraph (b5) of this section shall be made by that part 119 certificate holderoperating the particular device to be used.[Doc. No. FAA-1998-4954, 64 FR 1080, Jan. 7, 1999]But hey--is a minidisc a portable voice recorder? Quote Link to comment Share on other sites More sharing options...

Sparda Posted February 16, 2007 Report Share Posted February 16, 2007 I remember seeing this show before where they tested using electronic devices of all sorts and nothing happened. I think it was because the frequencies used in that plane was 2.4ghz so they were not affected. Also the cables were shielded. Do note that this was a modern business jet they tested in. But I guess you really wouldn't want to risk it would you? Quote Link to comment Share on other sites More sharing options...
