it could send it out of control that could take the plane of course or make it crash
you would make a phone call. nothing will happen if it was dangerous than when your at normal altitude they say you can unbuckle your seat belts and use electrical devicesAnswer by SweetNSexy
It interferes with signals that the planes trying to receive. You can use your phone as soon as the plane lands.Answer by Ken C
I was just on a flight where we were still on the ground in a long line at JFK waiting to be cleared for takeoff. I made a call on my cell phone and was told by a flight attendant to turn it off. I looked at a nearby flight attendant and said, “What about him?” This other flight attendant was in the front, chatting on his cell phone, probably doing the same thing I was: reporting to the destination that the plane would be late.
Suffice to say there are a few cell phone calls that are made by both flight crew and passengers when they shouldn’t be. But the key idea is to keep everyone from using electronic devices at the same time since this load might cause signal interference- no one wants to find out. Most airplane crashes happen during the takeoff and landing phase, and it is more safe to have your full attention to what is happening around you rather than chatting up a pal. Another reason is that it also keeps a quieter and more peaceful environment for everyone.
This is why I am usually a good boy and turn off my phone at the appropriate times for regulation purposes. That and the fact that I am trying to avoid calls from my boss.
Happy dialing (on the ground)
First, you could go to jail because it is against the law. Second, according to Myth Busters it won’t really do anything to the newer planes.Answer by flying.guy_canada

This questions keeps coming up so let’s answere it once and for all.
FCC Prohibits In-flight Use of Cell Phones, Its illegal!!!
Section 22.925 of the Commission’s rules, 47CFR Part 22, provides that cellular telephones installed in, or carried aboard airplanes, balloons, or any other type of aircraft, must not be operated while the aircraft is off the ground. The following notice must be posted on or near each cellular telephone installed in any aircraft: The use of cellular telephones while this aircraft is airborne is prohibited by FCC rules, and the violation of this rule could result in suspension of service and/or a fine. The use of cellular telephones while the aircraft is on the ground is subject to FAA regulations.”
However, the Commission has granted AirCell, Inc. (AirCell) and certain participating cellular carriers limited waivers of Section 22.925, to allow the use of AirCell equipment while airborne, subject to certain conditions. The AirCell equipment, which includes a modified cellular mobile telephone and specially designed aircraft antenna, is designed to avoid causing significant interference to terrestrial cellular systems.
Pursuant to appeals filed by certain cellular licensees opposing the Commission’s grant of such waivers, the United States Court of Appeals for the D.C. Circuit rejected petitioners’ claim that the Commission’s grant of the waivers unlawfully modified their licenses, but remanded the case to the Commission to further explain certain of the technical grounds for its decision. See AT&T Wireless Services, Inc., v. FCC, 270 F.3d 959 (D.C. Cir. 2001). This remand, as well as a separate request by AirCell to extend the duration of the waivers, are currently pending before the Commission.
Section 91.21 of the FAA rules (14. C.F.R. 91.21) prohibits the use of (with some exceptions) portable electronic devices while on board U.S. registered civil aircraft operated by the holder of an air carrier operating certificate, or operating certificate, or any other aircraft operated under instrument flight rules. The FAA has issued an advisory circular offering information and guidance for assistance in compliance with Section 91.21. Reference https://wireless.fcc.gov/error.htm
Reasoning behind the FCC Ruling
Cell phones at altitude …
Line-of-site communications to many cells Incompatible with ground frequency re-use pattern Causes interference with voice channels.
FAA Position on PEDs/Cell Phones
“(Advisory Circular 91.21-1A) … prohibits the operation of PEDs (Personal Electronic Devices) aboard U.S.-registered civil aircraft allows for the operation of PEDs which the operator of the aircraft has determined will not interfere with the navigation or communication system of that aircraft …”
Background information. Section 91.21 (formerly 91.19) was initially established in May 1961 to prohibit the operation of portable frequency-modulated radio receivers aboard U.S. air carrier and U.S.-registered aircraft when the very high frequency omnidirectional range was being used for navigation purposes. The Federal Aviation Administration (FAA) subsequently determined that other PED’s could be potentially hazardous to aircraft communication and navigation equipment, if operated aboard aircraft. Amendment 91-35 amended the scope of former section 91.19 to prohibit the use of additional PED’s aboard certain U.S. civil aircraft. Earlier studies conducted by RTCA, Inc. (RTCA), Special Committee 156, Document No. RTCA/DO-199, Volumes 1 and 2, entitled “Potential Interference to Aircraft Electronic Equipment from Devices Carried Aboard,” have contributed greatly to an understanding of the operational effects of PED’s aboard aircraft.
Section 91.21 allows for the operation of PED’s which the operator of the aircraft has determined wìll not interfere with the navigation or communication system of that aircraft. The determination of the effect of a particular device on the navigation and communication system of the aircraft on which it is to be used or operated must, in case of an aircraft operated by the holder of an air carrier certificate or other operating certificate, be made by that operator (i.e., certificate holder). In all other cases, a determination must be made and it may be made by the operator and/or the pilot-in-command (PIC). In some cases, the determination may be based on operational tests conducted by the operator without sophisticated testing equipment. When safely at cruise altitude, the pilot could allow the devices to be operated. If interference is experienced, the types of devices causing interference could be isolated, along with the applicable conditions recorded. The device responsible for the interference should then be turned off. If all operators collect this type of data with specific information, a large enough database could be generated to identify specific devices causing interference. The operator may elect to obtain the services of a person or facility having the capability of making the determination for the particular electronic device and aircraft concerned. The rule as adopted was drafted to require the air carrier or commercial operator to determine whether a particular PED will cause interference when operated aboard its aircraft. Personnel specifically designated by the air carrier or commercial operator for this purpose may make this determination. For other aircraft, the language of the rule expressly permits the determination to be made by the PIC or operators of the aircraft. Thus, in the case of rental aircraft, the renter-pilot, lessee, or owner-operator could make the determination.
There are certain devices, whìch by their nature and design, transmit intentionally. These include cellular telephones, citizens band radios, remote control devices, etc. The Federal Communications Commission (FCC) typically licenses these devices as land mobile devices. The FCC currently prohibits the use and operation of cellular telephones while airborne. Its primary concern is that a cellular telephone, while used airborne, would have a much greater transmitting range than a land mobile unit. This could result in serious interference to transmissions at other cell locations since the system uses the same frequency several times within a market. Since a cellular mobile telephone unit is capable of operating on all assignable cellular frequencies, serious interference may also occur to cellular systems in adjacent markets. The FAA supports this airborne restriction for reasons of potential interference to critical aircraft systems. Currently, the FAA does not prohibit use of cellular telephones in aircraft while on the ground if the operator has determined that they wìll not interfere with the navigation or communication system of the aircraft on which they are to be used. An example might be their use at the gate or during an extended wait on the ground, while awaiting a gate, when specifically authorized by the captain. A cellular telephone will not be authorized for use while the aircraft is being taxied for departure after leaving the gate. The unit will be turned off and properly stowed, otherwise it is possible that a signal from a ground cell could activate it. Whatever procedures an operator elects to adopt should be clearly spelled out in oral departure briefings and by written material provided to each passenger to avoid passenger confusion.
Telephones, whìch have been permanently installed in the aircraft, are licensed as air-ground radiotelephone service frequencies. In addition, they are installed and tested in accordance with the appropriate certification and airworthiness standards. These devices are not considered PED’s provided they have been installed and tested by an FAA-approved repair station or an air carrier’s-approved maintenance organization and are licensed by the FCC as air-ground units.
The U.K.’s air safety regulator has released research about cell phone use on planes, warning of the serious effects that it can have on a plane’s navigational equipment.
The Civil Aviation Authority research found that standard cell phone use can cause a compass to freeze or to overshoot its actual magnetic bearing. Also, flight deck and navigation equipment indicators can be rendered unstable and inaccurate, and transmissions can interfere with critical audio outputs.
Cell phone use has long been banned on airplanes, along with use of many other electrical devices. But passengers have often accused airlines of being over-officious in their enforcement of the ban, even suggesting that it is unnecessary. Many airlines have had experience of passengers who are willing to break the ban in order to make a call. This latest research may frighten passengers into compliance with the rules.
A number of anonymous posters on the Professional Pilots’ Rumour Network–a popular online community for airline pilots and crew–expressed mixed feeling over the findings.
One poster said: “Occasionally during the taxi out, we overhear the characteristic rapid chirping of a mobile phone through our headsets. More often than not, it turns out to be a crew phone, we switch it off, then continue with no ill effects.
“Sometimes, however, it becomes necessary to hold clear of the runway and make (an announcement) reminding (passengers) to switch their phones off. At the very least, something back in the cabin is emitting enough of a signal to be picked up by the cockpit intercom. I think that once in a while I have observed deviations in some of the aircraft (navigation) kit while the interference is going on.”
Why can’t I use a regular cell phone in an airplane?
FCC regulation 47 CFR Ch.1 (10/01/98 Edition) says: Section 22.925 Prohibition on airborne operation of cellular telephones installed in or carried aboard airplanes, balloons or any other type of aircraft must not be operated while such aircraft are airborne (not touching the ground). When any aircraft leaves the ground, all cellular telephones on board that aircraft must be turned off. The following notice must be posted on or near each cellular telephone installed in any aircraft: “The user of cellular telephones while this aircraft is airborne is prohibited by FCC rules, and the violation of this rule could result in suspension of service and/or a fine. The user of cellular telephones while this aircraft is on the ground is subject to FAA regulations.” The minimum fine is $ 5,000.00 dollars at this time.
No it doesn’t interfere with avionics. Some avionics are
sensitive to devices with an IF frequency between 90 and
135 MHz. Cell phones don’t have that IF frequency range.
The disruption happens outside the plane as 20 to 30 cell
towers try to lock on to your signal at once. The cell
phone/airplane restriction was imposed by the FCC
not the FAA. Early cell phones had frequencies that could
disrupt navigation receivers up front. That technology is
long out dated. Now the frequencies are higher and MIGHT
cause a quick glitch on a weather radar return. The risk
has been blown way out of proportion to scare passengers
into compliance. Still, you could get a stiff fine from the
FCC if someone presses the matter.Answer by Jude
well all ATC communications during taxi, take off and even in the international Airspace (Aerospace center) to and from your destinatin Airport would be disrupted interrupted hard to listen and even 0 communication thus the pilot and other flight deck officers woould then maybe be panicked stricken so if you want to arrive safely and soyundly to where you want to go, never use cellphones and just listen to the Pilot and other crews on board as they are very reliable in terms of safety and emergency during the flightAnswer by John B
If a cell phone could hurt an airplane I’d have been dead long ago. My boss will never hang up and I’m not about to tell him to. They do not hurt the avionics in any way. The biggest problem you might cause is to your next bill. Roaming charges you see.Answer by David N
Mythbusters did their test on a small analog plane.
Modern digital planes can get static and misreadings if you use a cell phone…ever get a cell phone call at home or work? Notice all the annoying loud static you get on your speakers?
Same thing happens in a pilot’s headset, which can cause him to miss important ATC commands, like telling him to turn to avoid a collision…Answer by Kyle
Ok, well actually a couple of you are wrong. If you didn’t know, Cellphone frequencies are the same frequencies that the GPS systems on the aircraft use. Also, some cell phones disrupt sertain avionics such as an ILS system or a VOR. I had a professor who tested it in a Cessna Citation Business Jet. It threw him off course. Also, if you have Nextel, you already know that it creates a “ticking” noise when making a call or recieving a call in speakers. Well, that will affect the pilot’s headset. I know when i fly, and i leave my cell phone on, my headset acts up. I’ve also had a commercial airline flight where during decent the pilot came on and literally yelled over the PA saying that someone was using their cell phone and distrupting the avionics.
Anyway, for those of you that have said it doesn’t affect anything, you are wrong, and i’m sorry to be so frank. Don’t put your life or anybody’s life in danger, by using your cell phone or any electronic device that transmits any signal unless you are given permission to. It’s just worth dying over, if you ask me.Answer by DanMan
You might get really lousy reception.
No seriously, there is no affect on the airplane as we know right now. Its not like if you use your cellphone the plane is going to spontaneous combust. Feel free to use your cell phone on a plane, just please, please, be courteous to others.Answer by tophat0246
Nothing would happen to any of the controlls. They prohibit them for several problems:
1.Annoyance of ther customers
2.No reception that high up (past 18,000)
3.When your cell phone is on in the plane and is roaming, it switches towers every few seconds and that costs the phone companies more cash.Answer by Andrew
Not much would happen, but a flight-attendant would tell you to get off your phone. Airlines ay it will interfere, with the navagation system with the airplane.Answer by kj
It could mess with the radio system on the plane and send it crashing. I advise your to listen to the airlines when they say not to use it.Answer by Dangermanmi6
I work with avionics and ground based Nav Aids, regulatory issues aside the only thing that most likely will happen is you will annoy the heck out of the passenger beside you. To be brand spcific Motorola handsets will cause interference with my car radio and my computer speakers when they start handshaking with the cell site to command the handset to ring. As a former pilot , ham radio operator and electronics technologist I can tell you that the interference is minor and would not cause any plane to crash and burn.
The poster who said that the signal would be picked up by many cell sites IMHO is correct in that the signal would be picked up by many sites at once but the one with the strongest received signal SHOULD grab the call. Also there was a problem in the early analogue days of mobile communications being that the computers and other hardware weren’t fast enough to do the hand offs required for a jet in flight. Today is anybody’s guess.Answer by Chris
you are not supposed to use cell phones on the plane
