Basically it turns off any kind of communication from the iPad, as wifi or bluetooth, so it doesn't interfere with the airplane communication service...
Is there scientific proof that cell phones can make planes go haywire? Some. In 2003 the Civil Aviation Authority--the FAA of the United Kingdom--ran tests using simulated cell phone signals in a chamber (not in an actual aircraft) and found problems. In some cases, the compass froze, some instruments displayed errors, and audio communications were difficult to hear due to interference.
As a practical matter, these devices do not create interference for aircraft.
It turns off all of the radios so that the device is in compliance with FAA rules.
As a practical matter, these devices do not create interference for aircraft. A significant number of uses fail to turn their phone/tablet to "airplane mode" before flights. Their phones will merrily seek to establish connections to cell towers; planes don't crash because of this.
"Airplane Mode" is useful for any time that you want to shut down all of the devices radios and conserve power.
It's true that most consumer mobile devices don't interfere with aircraft systems, however there are a minority that do. And since it would be too tedious to test every single model of tablet and phone to see if it would interfere with aircraft systems the FAA had to simply ban all mobile devices from operating their wireless systems during flight.
What evidence do you have that shows this to be true? The FAA has NEVER studied this. The only study is from the UK and they used SIMULATED cell phone signals, not real cell phones.
This whole thing is a myth, started by poor science. The FAAs electronics genius accepted the UK study because there MIGHT BE a chance of interference, not because there was any proof of actual cell phone interference.
Since 1991, the Federal Communications Commission (FCC) has banned the inflight use of 800 MHz cell phones because of potential interference with ground networks. This ban requires that in addition to the testing the FAA requires to show non-interference to the airplane systems, an airline would also need to apply for an exemption to the FCC rule before it could allow cell phone use inflight. The FCC proposed modifying this ban in 2004, but subsequently withdrew the proposal based on the comments it received.
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.
IT's not the radio's in current electronics that's really the problem. The trouble is that they don't know what effect newer radio/aerial/whatever communication technology will have an aircraft navigation. So, it's safer to get them all turned off. Fair enough if you ask me.
I'm starting a class action lawsuit against Apple. Not once has my iPhone or iPad transformed into a plane when I switch on Airplane Mode. =(
If they ban cellphones on airplanes, why don't they ban WiFi on them too?

In-flight WiFi is provided via a single incoming satellite connection which can be switched off at the will of the flight crew, which is totally different to hundreds of people having outgoing connections with nearby cell towers. Think of it this way - sometimes when you get a huge crowd of people that all have their cell phones switched on (eg. sporting events), it may 'overload' the network in that area and as a result the coverage may not be as reliable as it normally is. While it is yet to be 'proven' (but to be honest, it's a case of better safe than sorry; god forbid the day we lose an aircraft due to interference), it may be possible that the same kind of interference could occur to the instruments inside the aircraft.
However, I would like to point out that this ban is simply related to transmitting devices - devices that send out a signal - which is why cell phones have the Airplane Mode option. The reason why flight crew ask for devices to be completely turned off for taxi, take off and landing is nothing to do with interference at all; it's so the passengers pay attention to the safety demonstration, and so they are more attentive in the event that a sudden evacuation is necessary (hence why electronic devices can be used after the seat belt sign has been dimmed).
It would make little sense that airports have implemented severe enough secure measures to cause long screening delays, make us remove our shoes, require us to surrender beverages, grooming accessories and nail clippers if all that's required to take down a plane is a cell phone.
The regulation was put in place in 1961....according to the FAA website. They were concerned with radios, not cell phones. They have simply updated the wording since to cover each emerging technology.
You should present your case before the FAA and get the rules changed.
"If it please the panel, I seriously did like 15 minutes of google research, I really and honestly know what I'm talking about better than you!" I'd put it in a really condescending tone, that way they know for sure that you mean business.
Think of it this way...do you really want to sit on a plane cross country, let alone crossing an ocean, and listen to over 200 people talking on their cell phones?
