why cant u use your cell phone on a plane if it has signal and it is working fine?

Answer 1

It has been alleged that it could possibly interfere with the navigational equipment on board the aircraft. The truth is that this has never been proven.

In fact, the airlines are working furiously to be able to provide a satellite link that will allow you to use your cellphone in flight. Some airlines in Europe and Asia already offer wireless internet access in-flight. None of this would ever be allowed if there were any truth to the rumor of interference from cellphones or wireless network adapters in computers.

Most cellphones won't work once you're about 5,000 feet above ground level anyway. The cell towers are designed to "look" for phones close to the ground, not in the air and the signals are focused towards the ground. Also, aircraft move fast enough that the phones can't link up to a tower quickly enough before they're out of range of the tower.

I work for a large company that has several corporate jets. I fly on them several times a year. The crew could care less if we use our cellphones. Once we take off, they work for a few minutes and go dead at about 5,000 - 6,000 feet altitude.

BTW, cellphone frequencies are nowhere near the frequencies used by aircraft communications and navigational systems. Although there is a very remote chance of harmonic interference, cellphones work on the 5th harmonic or higher so the real chance of interference is virtually ZERO!

Answer 2

Well definitely now not however there's a small likelihood. Telephone phones can rationale electromagnetic interference with the plane avionic methods (take your telephone close to a television or a speaker and you'll be able to see for yourself) and this in flip could motive the plane to crash (it is on no account happened) Now, if in case you have a guy at the back of a aircraft attempting to use his cell nothing will happen but think now a giant aircraft with a number of hundred humans, all trying to use their cellphones... The threat of interference acquired a hole lot better. Utilizing a telephone within the air may additionally pose big issues to the phone cell manufacturer. Phone phone networks aren't designed to control cellphones "within the air". It is unattainable to grasp which tower to use and bouncing between towers requires gigantic processing energy by way of the cellphone phone company. Once again, having a few guys do that is no large deal however assume a enormous cities with enormous quantities of flights a day. If handiest a fraction of the passengers try to use their mobile, it might purpose the whole phone network to crash. Additionally once you reach 5000 ft or so, you will not be capable to make use of your cellphone anyway (it most effective takes 2-three minutes to arrive that altitude) so all this chance for only some minutes of speak time. So it can be now not due to the fact there's this conspiracy, it is without problems on the grounds that cellphones should not designed for use at excessive altitudes. Satellite telephones exist for that reason and new technological know-how is being developed.

Answer 3

Well absolutely no longer however there's a small likelihood. Cell telephones can intent electromagnetic interference with the plane avionic techniques (take your mobilephone practically a television or a speaker and you'll be able to see for your self) and this in flip would possibly intent the plane to crash (it is by no means occurred) Now, in case you have a man at the back of a airplane making an attempt to make use of his mobilephone not anything will occur however think now a tremendous airplane with a number of hundred folks, all making an attempt to make use of their cell phones... the chance of interference acquired a gap lot greater. Using a mobilephone within the air too can pose massive disorders to the telephone cellphone manufacturer. Cell cellphone networks aren't designed to manage cell phones "within the air". It is unimaginable to grasp which tower to make use of and bouncing among towers calls for massive processing vigor by way of the telephone cellphone manufacturer. Once once more, having a couple of men do that is no tremendous deal however think a tremendous towns with countless numbers of flights an afternoon. If just a fraction of the passengers attempt to use their mobilephone, it would intent the complete mobilephone community to crash. Also whenever you succeed in 5000 ft or so, you will not be ready to make use of your mobilephone besides (it handiest takes two-three mins to arrive that altitude) so all this chance for just a few mins of speak time. So it is not considering that there is this conspiracy, it is easily considering that cell phones aren't designed for use at top altitudes. Satellite telephones exist for that rationale and new technological know-how is being constructed.

Answer 4

It has more to do with the airline's investment in GTE Airphone rather than any legitimate safety concern. All modern day Avionics on any US aircraft is very heavily shielded against any type EMI. It has never been proven to interfere with any comm/nav system. It was originally thought that it might cause trouble but after that was not proven the ban was kept on for the sanity of your nearby passengers and the profitablilty of Airphone. After all, $3 per minute is a powerful deterrent to allowing you to use your free minutes.

Answer 5

Cellphones operate in the same frequency (2.4GHz) as many of the navigational equipment in the plane. This can cause a lot of problems with communication. Many hospitals and nursing homes do not allow it. If you have a wireless network, it can be affected too...if the network is operating at the same frequency.

Answer 6

Mostly because it monopolises many cell stations at once rather than just one.
Also there is an outside chance it can interefer with some of the nav equipment onboard.
Most nav equipment does NOT run in the 2.4Ghz range...but harmonics of this frequency can extend into the VHF/UHF range that aircraft avionics run in

Answer 7

properly maximum in all probability no longer yet there's a small chance. cellphones may reason electromagnetic interference with the plane avionic structures (take your cellular telephone on the point of a television or a speaker and also you may see for your self) and this in turn ought to reason the plane to crash (it is under no circumstances occurred) Now, once you've a guy contained in the decrease back of a airplane attempting to apply his cellular telephone no longer some thing will ensue yet imagine now a huge airplane with quite a few hundred human beings, all attempting to apply their cellphones... the prospect of interference were given a hollow lot higher. utilising a cellular telephone contained in the air may also pose significant issues to the cellular telephone business enterprise. cellular telephone networks are not from now on designed to address cellphones "contained in the air". it isn't plausible to attraction to close which tower to apply and bouncing between towers calls for significant processing skill by technique of the cellular telephone business enterprise. once back, having some adult males attempt it truly isn't any enormous deal yet imagine a huge cities with thousands of flights an afternoon. If only a fragment of the passengers attempt to apply their cellular telephone, it ought to reason the entire cellular telephone community to crash. also once you attain 5000 ft or so, you is purely no longer waiting to apply your cellular telephone besides (it only takes 2-3 minutes to achieve that altitude) so all this threat for very jiffy of communicate time. So it isn't any longer because there is this conspiracy, it is because cellphones are not from now on designed for use at extreme altitudes. satellite tv for pc phones exist for that purpose and new technologies is being stepped ahead.

Answer 8

Because the people who fly the plane are worried about it messing up its signals which would cause the plane to get lost and crash.

Answer 9

besides not driving the people around you categorically insane in a small enclosed space with no obvious escape routes? I think it has something to do with the communication system between the pilots and the ground towers and other airplanes. It screws with the frequency and interupts communication. And I can wait to call my friends if it means the safety of my flight.

Answer 10

It messes up the navigational equipment. It has been known to down a couple of planes in other countries.
