One of the requirements voiced by flight attendants before the plane takes off is a complete shutdown mobile devices or transferring gadgets to airplane mode.
The ban on working phones on board appeared about 20 years ago and exists to this day. Let's see why we are not allowed to talk on the phone in the air.
Why was there such a ban?
With the rise in popularity of mobile phones in the 1990s, airlines began to consider banning the use of such devices on flights.
In those days, aircraft equipment was poorly protected from all kinds of interference caused by the operation of electronic devices, especially mobile phones.
Indeed, during the flight, mobile devices are far removed from ground towers. cellular communication and increase the transmitter power several times so as not to lose the network or find it. The body of the aircraft acts as an additional barrier.
All phones on board begin emitting a signal at the highest possible intensity and may interfere with the operation of on-board instruments.
To date, not a single aircraft accident has been recorded, the cause of which would be an unplugged mobile phone.
All airlines quickly accepted the norm, and since then, before takeoff, we constantly hear a similar warning.
Technology doesn't stand still
The electronics in modern aircraft are much better protected from interference and interruptions than they were a couple of decades ago. All aircraft systems operate at completely different frequencies, and even theoretically smartphones cannot interfere with them.
The only thing that can be affected by a working phone is the intercom system of the team with passengers. If you hear the message of the main pilot with interruptions or clicks, most likely someone did not turn off the mobile.
So why haven't they allowed conversations in the air yet
Some airlines have already installed portable base stations on board so that passengers can use telephone connection during flights.
However, the public still does not come to a consensus regarding the permission to telephone conversations during flights. It is one thing when a business man in business class will talk, and quite another when they are allowed to call a fussy talker sitting in the middle row.
The main reason for the existence of the ban is the reluctance of airlines to spend money on expensive research.
The European Aviation Safety Agency stated back in 2014 that the included electronic devices do not pose a threat to flight safety. But this statement is only a recommendation and is not the norm.
Whether or not to allow “on-board” calls is a personal matter for each airline, and no one wants to take such responsibility without evidence backed up by expensive examinations.
So it turns out that smartphones and phones do not affect anything during flights, and no one is in a hurry to allow them to be used.
Every year, mobile devices become more and more perfect and hide in their miniature body an increasing number of functions and capabilities. But not all cell phone owners are aware of all the capabilities of their phones. In this article, you will learn what the offline mode of a mobile device is and why a regular user needs it.
Any mobile device, be it a regular phone, a communicator or a tablet with support for calls, can work in several modes. If things like “normal” or “silent” mode are familiar to almost everyone, then some of the “states” of the cellular still cause a number of questions for most users. The standalone mode also applies to them. Let's finally find out what it is for and when it is worth (if at all) turning it on?
Offline mode in the phone appeared a few years ago. Some manufacturers of mobile devices have chosen this way to get around the problem associated with the use of mobile phones during air travel - after all, as many know, previously cell phones could not be used during the entire flight, which could last more than ten hours. The new mode allowed owners to keep their gadget on, but limited their access to cellular networks. Thus, the “flight mode” (from the English “fly mode”) - this is how this function was presented by several mobile device manufacturers - allowed you to keep your cell phone on. Despite the fact that in this state the phone cannot communicate with the operator's network (and, accordingly, you will not be able to use it for its intended purpose, that is, make a call), during a long flight, a passenger could play games, read and listen to music using your favorite cell phone. Over time, autonomous mode gained wide popularity and began to be used much more often on the ground than during air travel.
What is the reason for such a prevalence of such an unusual regime? It would seem a paradox - to use the phone without using it for its intended purpose, but with the development of technology, this is exactly what many users lacked. And after the offline mode appeared, the cell phone could be used as a digital camera, player, game console or e-book without fear that someone will distract you from your favorite pastime with their annoying calls!
But offline mode has other benefits as well. For example, if you find yourself in an area so far from civilization where you can only dream of coverage, your phone will constantly try to “find” a network, which will drain its battery many times faster. In such places, you can either turn off the mobile at all, or use the "fly mod". When you are closer to civilization again, just turn off the offline mode and the phone will immediately find the operator's network. This is exactly what experienced tourists usually do, who already know where it is worth keeping the mobile in normal mode, and where it is desirable to save battery power for future conversations.
But there is an offline mode and one undeniable minus. In some models, when it is turned on, not only the GSM module stops working, but also Wi-Fi, and sometimes even GPS. This is due to the fact that in such phones and communicators, when this mode is enabled, the phone turns off all radio modules at once. In fairness, it should be noted that in many models, even in the “fly mode”, GPS and Wi-Fi work when you turn it on again.
Thus, we can conclude that the offline mode is a thing necessary not only for fans of frequent air travel, but also for a huge number of “mundane” users. The main thing is not to forget to turn off this mode in time, otherwise you may not wait for an important call.
What is "Airplane Mode" on a cell phone?
Olga naked
When turned on, the mobile phone continuously sends and receives a radio signal. However, in some places, this signal may interfere with the operation of the main equipment. That is why, for example, in airplanes or near operating rooms, the operation of mobile phones is prohibited. Before takeoff, all passengers on the flight are asked to turn off mobile phones.
"Airplane mode" in a mobile phone allows you not to turn off the device completely. In this mode, only the radio unit of the phone is turned off. At the same time, other functions, such as the player, games or folders with files, are available for use.
Airplane mode is a useful, and for many people, indispensable feature.
Why do you need airplane mode in mobile phones?
Danila Maltsev
that you play games on your mobile phone during the flight.
that is, it does not send or receive any signals - which does not prevent instruments from flying.
and you can delve into the pipe itself, listen to music, watch the daily routine, etc.

Airplane mode disables the phone's cellular radio, Wi-Fi, and Bluetooth wireless transmission features. However, Wi-Fi is now on board many aircraft, and cellular communications may soon appear on them. So what's the use of Airplane Mode?
Even if you're not flying at all, Airplane mode lets you quickly turn off battery-draining radios. It extends the battery life of the device, provided that the wireless connection is not used.
Whatever device you own - Android phone, iPhone, iPad, Windows tablet 8 or something else - airplane mode disables the same hardware features for all devices. These include:
Cellular: Your device will no longer communicate with cell towers. You will not be able to send or receive anything via cellular network– no voice calls, no text messages, no mobile data.
Wi-Fi: Your phone will stop scanning for nearby Wi-Fi networks and trying to connect to them. The existing connection to the Wi-Fi network will be terminated.
Bluetooth: This technology wireless communication, which applies to wireless headsets and other devices such as keyboards and mice, will also turn off.
GPS: Airplane mode disables GPS reception on some devices. GPS is different from all of the above technologies - a GPS-enabled device only listens to received GPS signals without transmitting anything. However, for some reason, it is forbidden to use GPS on board some aircraft.
When airplane mode is enabled, the top notification bar Android devices, iPhone and iPad displays the airplane icon. They can be used on an airplane, even during takeoff and landing, provided the flight mode is activated. It is not necessary to turn off devices.
Regulations in many countries prohibit the use of signaling devices on commercial aircraft. A typical cellular phone or tablet is in contact with several cell towers and is constantly trying to maintain a connection. If the towers are far away, the phone or tablet amplifies the signal to communicate with them. This kind of communication can interfere with aircraft sensors and theoretically cause problems with sensitive navigational equipment. This concern led to the aforementioned rules. In fact, modern hardware is fault-tolerant. A plane won't crash because a few people forgot to turn on airplane mode.
A more obvious problem is that due to the extremely fast travel, the phones on the plane would switch continuously from one cell tower to another. This would interfere with cellular signals received by people on the ground. In addition, the phone's battery would quickly run out and there would not be sufficient signal strength.
Airplane mode is also useful on the ground. It is excellent for saving battery power. Its radio modules spend a lot of energy maintaining communication with cell towers, searching for nearby WiFi networks and attempts to connect to them, waiting for incoming Bluetooth connections, and periodically checking your GPS location.
Activating Airplane Mode disables all radios. This blocks incoming calls and texts on the phone, but increases battery life. This mode is especially useful for a tablet that serves as a standalone e-reader.
Wi-Fi is allowed on a number of aircraft - in fact, many aircraft now offer paid in-flight Wi-Fi. Activating Airplane Mode always disables Wi-Fi. However, most devices allow Wi-Fi to be turned on after turning on Airplane Mode. Cellular signals will still be blocked, but Wi-Fi will allow you to connect to the aircraft Wi-Fi network.
Some devices allow you to turn on Bluetooth in Airplane mode. Whether this is acceptable depends on the airline and the current regulators.
Why does your phone have airplane mode?
It is forbidden to use mobile phones during the flight in an airplane (it is believed that they can damage radar equipment). But in the "flight" mode, you can play, read books and use other functions. The phone does not communicate with the base station in this mode.
Airplane Mode and Offline Mode are the same thing. In some phone models, the modes are called differently. One function is performed.
It is forbidden to use a mobile phone while flying on an airplane.

In the "Flight" mode, the mobile phone falls more smoothly, plans literally. Therefore, the risk of breaking it is sharply reduced.
And the included "On the street" mode will tell you where to look for a mobile phone in case of its loss.
airplane mode- a special mode of operation of the device, available on all modern smartphones and tablets. In this mode, all data transmission and reception modules are disabled: calls, EDGE/3G/LTE, Bluetooth, Wi-Fi, etc. It also turns off GPS, although some manufacturers leave it on.
This mode is so called because it is often recommended to turn it on in flights. It is believed that signal transmission modules can affect the operation of aircraft systems. Some airlines prohibit the use of smartphones even in airplane mode. Depends on airline policy. I personally came across a situation where a flight attendant selectively checked whether or not the airplane mode was on for passengers.
How to turn it on?
There are two ways…
Settings->Airplane Mode. Turn on the switch.
Swipe up at the bottom of the screen. We call the control panel. There is a button to turn on/off airplane mode.
What can you use airplane mode for?
This is what I use it for most of the time. It happens that the cellular communication module switches to EDGE mode. Often this happens at sports competitions with a large crowd of people or in some not particularly populated areas of the city.
If you turn on airplane mode for a couple of seconds, and then turn it off, then it is likely that after connecting you will have 3G / LTE working. I don’t know how everything is arranged with cellular companies: perhaps, when connecting to the tower, the user is given some kind of priority. The funny thing is that if you do not change the place of deployment, then after some time (3-5 minutes) the network itself switches back to EDGE. But this is how it works...
Read messages without a read receipt
iOS itself allows you to turn off "Read Receipt" for all contacts.
Settings->Messages->Read report. You need to turn off the switch.
But if this does not suit you, then use the above life hack.
Extending device life
Airplane mode significantly extends the life of the iPhone, iPad, iPod. Devices use a lot of energy to connect to Wi-Fi and cellular networks. Moreover, the more unstable the signal, the more energy it takes to search for this signal ...
Example. I often use the iPad for movies and games. So what's the point of keeping Wi-Fi and a cellular module on there? I turn on airplane mode. According to my estimates in airplane mode, the tablet does not work for 10 hours, but all 12-13.
Often, developers include ads to monetize their app. They try to make ads either annoying (to make you want to click) or not (to get more views). These ads bring in a good income, but they are of no use to users. Sometimes it just covers part useful information displayed on the screen.
- close the application completely. That is, remove it from the taskbar (double-click home buttons and then pile up the app),
- turn on airplane mode
- turn on the application.
iPhone/iPad for children
Turn on airplane mode when you give the device to children. This is useful if you have a very young child who does not understand how to turn it back on. It is better, of course, to master parental control. This is suitable if you turn on offline videos for your child, games that do not require the Internet.
Completely hide notifications
Sometimes you want to temporarily hide annoying notifications.
I will give an example from life. I often record gameplay for game reviews using Quick Time Player. And sometimes I forget to turn on airplane mode. In this case, periodically some game reminds of itself. Or a message arrives that could wait... You have to record the video again.
Or you want to record Timelaps (a long video that records pictures at certain intervals) or just a video, and then you get an unexpected call and 10 minutes are wasted. Most reliable way do not interrupt - turn on airplane mode!
When exploring their first Android device, novice users are wondering what is Airplane mode in it? What is it for?
Airplane mode in an Android smartphone or tablet (or offline mode) is the state of the device in which all transceiver modules are disabled:
- voice communication and SMS messages;
- wi-fi connection;
- bluetooth module;
- geopositioning modules (gps, glonass).
Depending on the model of your smartphone or tablet, this mode may also be called "airplane mode", "airplane" or "flight mode". Other functions that do not require signal reception and transmission will be available, ie. the user can listen to music, watch videos, play games, take photos and videos, etc.
What is Airplane Mode for?
A modern smartphone is a complex transceiver device that, when receiving or transmitting data, generates an electromagnetic signal that can adversely affect nearby sensitive electronic devices. Such sensitive devices include aircraft navigation equipment and, although it is seriously protected from external electromagnetic interference, nevertheless, flight safety rules require phones to be turned off or switched to airplane mode while on board.
Of course, the flight mode can be turned on anywhere and at any time, for example, when it is undesirable for the smartphone owner to receive calls and SMS messages. In addition, when the airplane mode is on, it saves a lot, which can be useful when you are in an area of \u200b\u200ba weak signal, when the phone spends too much energy searching for a network. Just turn on the flight mode until you get into the coverage area.
How to turn on airplane mode on an Android smartphone
Let's consider the inclusion of the "in flight" mode using an example Meizu smartphone M5 and Android 6.0 Marshmallow. In other phone models, the sequence of actions is approximately the same and should not cause difficulties.
Now you know what in-flight mode is and why you need it.
Flight mode is in everyone modern smartphone based on Android. Well, if not everyone, then almost everyone. But what is it? Not all users know the answer to this question, although, it should be noted, this mode can be very useful. Airplane mode (sometimes referred to as autonomous mode or airplane mode) is a mode that stops signal transmission, including:
- Cellular signal
- WiFi
The phrase “Flight Mode” itself already suggests that it is recommended to use it when flying. This is true, it is not in vain that during the flight it is required to turn off mobile phones, smartphones and other devices that can cause disruptions in the operation of aircraft systems. However, even if you never fly in an airplane, this functionality can be used all the time on the ground. Have you forgotten that this mode turns off the cellular signal? This great way remain inaccessible to other subscribers, if necessary. At the same time, what is important, the smartphone itself can not be turned off. And to turn on the network, just turn off the airplane mode.
Another extremely important detail: Airplane mode stops data transfer, while you can freely use your smartphone, for example, play games, watch videos, listen to music, etc.
Please note that if Wi-Fi was turned on when Airplane Mode was enabled, it will be turned off when the function is activated. However, even in this mode, you can easily turn it back on and it will work.
On most smartphones, flight mode is indicated by an airplane icon in the status bar. Here is an example for samsung galaxy:
On the same Samsung Galaxy, on the lock screen, in addition to the airplane icon, you can see the inscription “Airplane mode”.
The easiest way to turn on Airplane Mode is by calling the Quick Access Toolbar. In our example, you need to tap on the "Airplane Mode" icon.
Once activated, the icon will change color. And remember that you are left without communication - no one will call you, you will not be able to receive SMS messages.
Also, "Airplane Mode" can be enabled through "Settings".
But it seems to us that the quick access panel is still more convenient to use.
