Mobile phones on aircraft - WikipediaQUOTE (Wikipedia)
The use of mobile phones on commercial aircraft is generally forbidden during flight. The most well-known reasons for this banning is that the mobile phone could interfere with the sensitive equipment on the aircraft, and the interference with ground based networks. This policy is often based around the fact that during development, many aircraft were not designed to accept signals from mobile phones and there has not been sufficient testing to be sure that they could.
We had a discussion concerning why mobile phones can not be used on planes. No one knew the specifics and several points were brought up, but does anyone have more specific reasons than those listed in the link above??

Since the phone is occupying its frequency and channel in all of the cells its signal reaches to, that frequency and channel cannot be used by any other phones in any of those cells because of interference, resulting an an overall decrease in the cellular system's capacity. This is the primary reason the U.S. Federal Communications Commission prohibits the use of mobile phones in the air. (The U.S. Federal Aviation Administration is more concerned with interference to aircraft systems.)
I was interested more in the parenthetical statement above. Is this interference defined, conjecture or unknown?

I think my major problem would be if they didn't restrict it to certain areas of the plane. On a six hour flight if the person next to me is yapping away loudly on the phone (as in buses and trains) I would not be so pleased.
Just imagine if in that confined space of a plane you had 20% of the plane all talking over on another.

As far as I am concerned, the real reason behind not being able to use the mobile on the plane is due to possible interference with the flight system.. Why else would you not be allowed to use it in new busses or cars with ABS or gas stations.. etc. anyway?
Almost every advanced electrnonic equipment runs a clock. Meaning it does some tasks in every clockcycle.. Active electromagnetic wave transmitting devices like mobile phones for example, may interfere with this clock and result in strange behavior of the device.
I once read something about a bank close to the airport and the huge radar in the airport interfering with the computers in the bank, causing problems in account information and stuff..
Most probably the plane will not crush or your cars ABS will still function when you need it but why take the chance?

I ran a sound system for a play in an auditorium and when people had "electronic equiptment" going it really sent the system into feedback with all kinds of noise. The worst was a portable CD player that this one idiot kept listening to backstage.
I don't feel that it is wrong to ask people to 'unplug' for 10 minutes.
reason enough might be if todays london "attack" is proven to be same as the Madrid bombs

I saw a show on BBC some time ago and it proved that mobile frequencies don't interfere in the airlines signals, and this was proved (i think) by Boeing.
So, it's just the matter of time, when it will be allowed.
By the way, have anybody of you tried to keep it SWITCH-ON (silent mode) say by mistake, if it worked, then technically it would NEVER hamper in the airline signals.
Enjoy!!!

edit: i just remembered, i saw the same logic of proving it doesn't interfere in signals on Brainiac too

There are reports on the net that the German Aircraft Safty Dept (FAA Equiv) will be allowing the use of cell phones on carries in germany starting soon. Other countries are watching this as a "wait and see"...
The FAA is also considering allowing Cell phones on airplanes, but is also
waiting to see the results of the Germans..
Airbus will begin installing hardware for this on its A320 series of A/C starting soon..
Phones could only be used during cruising, and not during landing/takeoff
I'll see if I can find some more Info.
My understanding was that there was anecdotal evidence that the mobile phone signals could interfere with the aircrafts navigation systems inparticular the ones which detect landing beacons. However there is to my knowledge no hard evidence for this.

Technically, whether u use your phone or not, if it's switched on then u r sending and receiving signals to the base station or tower. So if somebody tried to keep it switched ON on-board, and nobody noticed the interference, then laws should be changed...
But security could also be a concern while using mobile phones on board, as terrorists can use it for many other different purposes...

The other side of that was seen during 911, where passengers on some of the
planes managed to contact the police,FAA,FBI and tell them about what happened..
Here are some of the links I've found
EC backs inflight mobile callsQUOTE
European aviation authorities say that mobile phones would improve security on commercial air flights without posing a safety risk to the passengers on-board.

The Register - Germany greenlights mobiles on planesQUOTE
The German Federal Ministry of Transport, Building and Housing will next year lift the ban on the use of mobile phones on commercial flights, according to German newsmagazine Focus. The German Aerospace Centre (DLR) says that mobile phone signals do not interfere with onboard electronics. Several European airlines say that they too are considering the removal of the in-flight ban on GSM phones.

But if you see the darker side of it, phones on-board can be used to co-ordinate terror activities and proceed in much systematic manner...
Well, it's always upto the user to get benefit from the technology or to take undue advantage of the same, but on the personal frot, i always support use of technology...
Supressing use of technology is no solution...
Mobiles should be allowed on-board.

Oh joy,
mobiles may soon be allowed on planes in Europe, so now all those boring bastards who think they are so important that they cannot be out of contact for a couple of hours, will be shouting down the bloody phone disturbing everybody else.*

Some more information on this:
QUOTE
Several airlines, including Air France, have already launched a trial of in-flight mobile phone services on some European routes. British Midland's bmi, Portugal's TAP and low-cost airline Ryanair are also planning to offer services later this year.
Germany's Lufthansa, however, said Monday it did not want to introduce the service.
Surveys had shown that a large majority of customers were against it, Lufthansa spokesman Jan Baerwalde said.
"People don't want to be disturbed," Baerwalde said. Lufthansa will, however, look at providing fast Internet access on its planes, a service it already offered from 2004 until the end of 2006. The airline is currently looking for a new service partner to reintroduce the service.

Depends.. If they charge 1-2 Eur per min. for in-flight calls (Still much lower than the 10-12 USD Airphone used to charge)
Your not going to have to many annoying people/calls, for fear of running up a huge bill.

I was about to link to that
Clive James article; one of the best pieces of journalism I've read on the BBC News website.
QUOTE
Someone in the telecoms industry was quick to reassure us that passengers on aircraft would be more likely to send texts or e-mails than talk on mobiles. He said: "Social norms, as well as excessive background noise, may dissuade most people from making phone calls in crowded planes."
But I have already met Social Norm, and I know all too well that Social Norm never dissuades anyone from making mobile phone calls. Social Norm is the one making the mobile phone calls. The excessive background noise, on any form of transport, is made by a score of Social Norms shouting their thick heads off, and all it does is make them shout louder. I also invite you to note the abyss of misunderstanding that lay behind the spokesman's contention that "most people" would be dissuaded from making mobile phone calls on crowded planes.
But surely unless everybody can be dissuaded, then it would take only one mobile phone user to turn a long-distance flight into a journey through Purgatory.

I wonder how long other airlines, like Lufthansa, who are holding out on the service will continue to be able to do so?
I imagine that most of the traveling public won't like the idea of allowing phones on planes, however it won't persuade them off the airline if they can get the ticket cheaper.
However, on the other side, I imagine companies booking flights for their employees could see this as a major bonus, and be willing to pay whatever surcharge is necessary.
As such, I think all airlines will fold and introduce this in the future.

My employer books the cheapest possible flights & if two people could squash into one seat they'd book that as well.

They should make it available in business class only. Therefore anybody or worse anyone's company who insists on being 1000% reachable will have to pay for the privilege. I know too many people who suffer from "connectability" and the dreaded berryisation of the business world.
