Why cell phone usage on airplanes in flight is restricted?

Licensing.

I have a good friend who is a senior pilot for one of the major airlines. He's a USAF Academy graduate and retired military pilot. When I asked him about the restriction against cell phone usage being credited to interference with aircraft flight systems he burst out laughing. He claims no such interference exists and that he's used his cell phone in the cockpit while the plane was in flight.

He claims that every radio transmitter on an aircraft in flight must be licensed by the FCC. Your cell phone lacks a license for use on an airplane in flight. Therefore you can't use it.

Ever wonder why you're supposed to turn off your cell phone before the plane pulls away from the gate but it's OK to turn it on after your aircrafts lands and is taxiing to the gate? It's due to the definition of the term "in flight": an aircraft is considered to be "in flight" from the time it pulls away from the gate until it touches down at its destination. In other words taxiing away from the gate to the runway is considered to be "in flight" activity but taxiing after landing is no longer considered "in flight" activity.

He claims that the FCC is in discussion with the cell phone carriers about licensing the use of cell phones while airplanes are in flight. In addition he says that the FCC will allow cell phone providers to charge cell phone users an extra fee for this privilege. He expects this will start to happen by the end of 2007.
 
Yeah I don't know how true your friend's story is, but I have heard the FCC is considering allowing cell phone use in flight. I've also heard that the network of cellular towers is not designed to handle cell phones moving 500 miles per hour 5 miles directly above the tower. Not sure how true that is either. In any event, allowing cell phone use on airplanes will take us to a new high in rude cell phone use.
 
u can totally use your phone fvcking i went to hawaii and bunch of people did not turn off their phone.. we didn't crash..

a few times, some lady said i left my blackberry on in my luggage and the flight attendance say im sure the battery will drain out in a few minutes with a wink..

im like i hope we dont crash and burn..
 
The other reason: in turbulence or a crash, the cell phone is a good projectile sized just right to do maximum damage.

It was never about interference. Remember pretty much anything the airlines tells you is a lie.
 
So what? I really don't want everyone on the plane talking on their cell phones. Have you ever heard the conversations these idiots have in the middle of public places?
 
it's because the towers can't track it properly.

and they tell you that you can't use phones until the cabin door is open again, iirc.
 
The last thing I want is 200+ people in a confined space trying to shout over each other ...."ARE YOU THERE?!!?!!?", "CAN YOU HEAR ME!!!!" "ZOMG I GOTS AN STD FROM YOU!!".....
 
Last time I flew cross country I left my phone on and regularly checked the signal. I would say it would be very unreliable as the signal meter was all over the place and I rarely had a constant signal for more than a few minutes.

But yeah, the claim that cell phones will make the plane crash is absurd... just as absurd as the idea that modern cell phones can interfere with hospital equipment or make gas pumps explode.

How bout it.
 
Actually if you look back you will note in the late 80s and early 90s when cell phone technology was just getting started people had legitimate concerns about the safety of a device using certain bands. They also had concerns about laptops.

However it was determined pretty early on that they werent a problem but the airline industry was working on an in flight cell phone service of their own they could charge ridiculous rates to use. I believe this service was call "AirPhone".

So they get the FAA to ban the use of cell phones so they can sell you the same service at 100x the cost.

In 1996 the FAA and Boening conducted a series of tests on a 737. They hit it in flight with a bunch of high powered signals in the same bands as the analog and digital phone systems. The effect was nothing happened.

The govt and the airlines and boeing have known for a decade cell phones are safe but they dont want to give up that airphone service that generates an estimated 150 million a year in revenues across the airline industry.

I just cant believe the crap people believe. As if the plane is going to fall apart mid air if my cell phone is turned on.
 
Airplanes are one of the few places left where one can get some peace and quiet...if you sit in first class especially.

Just image 80 board people talking on their phones in one room. No thanks. Keep cell phones out of the skies.
 
I'm pretty sure it's because it's hell on the towers to pass your call around? not sure.. but that makes sense from a technology standpoint.

What reason would he have to lie?

I didn't say he lied. His story could be as much an urban legend or rumor as the cell phones starting fires at gas stations thing was.

I always assumed it was because they weren't FCC licensed for airplane use. If they are not licensed, then they are not certified to cause or accept less than the required amount of interference. This doesn't mean that they do cause interference, it simply means that the manufacturer hasn't paid the fees to prove that it doesn't.
