The reason that electronics are not allowed during the first and last 10 minutes is that if there were a bizarre interaction, you might not have time to catch it and resolve it. At other times, the pilots could tell everyone to turn everything off to debug a minor navigation or radio problem.

Most electronics and even cell phones don't put out enough power in frequencies that are going to cause any problems. There is even talk about putting cells on planes to allow cell calls, relayed via satellite. Google: "cell service on commercial airlines".

The only reasonably possible way to interfere would be to tune an aircraft band radio to the tower frequency and block communications, but is an indirect risk.

As well All plane now have cell based communications for passangers who pay! So I think it is a money grab for the airlines. ]]>Mar 1st 2006 10:27AMhttp://www.engadgetmobile.com/2006/03/01/cellphones-could-disrupt-airplane-systems-study/http://www.engadgetmobile.com/2006/03/01/cellphones-could-disrupt-airplane-systems-study/Mar 1st 2006 11:03AMhttp://www.engadgetmobile.com/2006/03/01/cellphones-could-disrupt-airplane-systems-study/http://www.engadgetmobile.com/2006/03/01/cellphones-could-disrupt-airplane-systems-study/Mar 1st 2006 12:02PMhttp://www.engadgetmobile.com/2006/03/01/cellphones-could-disrupt-airplane-systems-study/http://www.engadgetmobile.com/2006/03/01/cellphones-could-disrupt-airplane-systems-study/Just another bunch of morons that have no clue about electromagnetics making judgements here.

I mean come on. It is a cell phone for GAWD sake. If they built planes in such a way as a laptop, cellphone, gameboy, iPod, iPaq, Palm, mp3 player, cd player can cause a plane to go haywire and fall out of the sky then the planes aren't safe.

IF they don't want you to bring them aboard because they are afraid of explosives fine...but security screening should take care of that.

I don't want to be irritated by people in close quarters on the phone either but it is silly that it could even be considered that a electronic devices can bring down a plane under normal usage.]]>Mar 1st 2006 12:23PMhttp://www.engadgetmobile.com/2006/03/01/cellphones-could-disrupt-airplane-systems-study/http://www.engadgetmobile.com/2006/03/01/cellphones-could-disrupt-airplane-systems-study/Mar 1st 2006 12:55PMhttp://www.engadgetmobile.com/2006/03/01/cellphones-could-disrupt-airplane-systems-study/http://www.engadgetmobile.com/2006/03/01/cellphones-could-disrupt-airplane-systems-study/Just another bunch of morons that have no clue about electromagnetics making judgements here.

That is what I'm saying...a cellphone shouldn't interfere enough for it to be a problem. It it is then we shouldn't be flying planes. It is beyond stoopid that anyone would build a comminications system for a plane that could be negatively impacted by a cellphone and vice versa.

Other than fist fights between seatmates I don't see any reason not to allow cell usage on planes.]]>Mar 1st 2006 1:41PMhttp://www.engadgetmobile.com/2006/03/01/cellphones-could-disrupt-airplane-systems-study/http://www.engadgetmobile.com/2006/03/01/cellphones-could-disrupt-airplane-systems-study/I have a SierraWireless 860 GPRS/EDGE/3G-HSDPA card in my laptop.

Man I could get tons of crap done if they allowed this.

If I have to endure someone blathering on their phone in the seat next to me DURING AN ENTIRE FLIGHT, I'll simply offer up my own choice comments to their conversation until they use text messaging or take it to the bathroom! It boggles my mind that someone can sit elbow-to-elbow next to a stranger, and carry on a phone conversation as if they're the only one there! It's the ultimate height of self-centered rudeness!]]>Mar 1st 2006 2:55PMhttp://www.engadgetmobile.com/2006/03/01/cellphones-could-disrupt-airplane-systems-study/http://www.engadgetmobile.com/2006/03/01/cellphones-could-disrupt-airplane-systems-study/
Modern receiver design precludes interference from low level sources, cell phones are not low level. Even though they only put out 300 mW, and possibly could overload a receiver front end, possible, but not very likely
