We were asked to be in our device or airplane mode due to electromagnetic interference from mobile phones, tablets, e-books, e-gaming headsets, and many, many others. Because some aircraft were built before this happened, the thing is, it took a little time for the industry to make sure that it was completely safe to use.

Until today, as you can see, even iPads and other tablet devices are in the cabin, which pilots use to store their documents, instead of taking large bags with them, real papers. You’ll see flight attendants, with tablets and big phones, either on the spot, or in addition to these piles and piles, and piles and piles of stamps, typographical and clerical work. All of these devices have been thoroughly tested to make sure there are no problems.

But that wasn’t always the case. In fact, back in 2011, there were nuances in some models, the cockpit, the screen on some Boeing 737 aircraft were sensitive to interference. If so, how can we know that it is a particular combination of planes, and control and solve it? During the testing process itself, which allows airlines to offer plane tickets online, and that’s exactly how it’s done. As part of this testing process, it is necessary to create enough electromagnetic interference to present an entire cabin full of instruments in various sizes, including some that do not work properly. Virtually every aviation equipment combo serviced by a major international airline, it has now been tested.
