The Airplane mode is usually a mystery in our smartphones, a function that, when activated, causes the mobile device to lose almost all the connectivity it has predetermined. It does not allow us to make calls, connect to the Internet with our data rate, or receive SMS, but it keeps many other functions of our device active.
The airplane mode has that name because of the obligation that still exists in some airlines, to turn off the mobile phones during a flight.
This obligation was lifted in all phases of the flight when airplane mode began to be fully extended on mobile phones and other devices, all by a prevention measure created to avoid interference with the crew’s aircraft and radio systems.
The airplane mode of your cell phone serves for much more purposes than to use it when you are flying.
Taking advantage of this function we can continue to use our smartphone in many ways, including:
1. Save battery:
One way to make sure that a device maintains its charge is to turn it off, but there is another option that will allow you to at least see photos, read documents or see what time it is: to put it in airplane mode, this way the equipment minimizes its activity. It is useful for example in an uncovered area. If the cell loses coverage, it will try to find a network, which will cause it to waste a lot of battery power.
2. Faster charge loads:
One way to optimize the time to charge the phone is to do so by keeping it in airplane mode, so connectivity, Wi-Fi, Bluetooth and GPS are off.
3. Save international roaming:
Traveling can be very expensive if we use the phone too much or if we inadvertently keep active features very expensive. One way to avoid this is to put the phone in airplane mode and use only the Wi-Fi hotspots that we find. We can send Whatsapp messages, check our email or use instant messaging systems without extra charges. But the device will not be able to receive calls or messages.
4. Avoid advertising in games and applications:
If we play with the phone in plane mode, chances are that we will not receive ads when not connected to the internet.
5. Avoiding Accidents:
The airplane mode can be very useful if the children use our phone to play, since it is likely that they could start to touch the screen and end up calling someone, but if the phone is in plane mode, they will not be able to make calls, In addition, this way they will not receive alerts that interrupt the game.
6. Avoid Distractions:
If we are in a meeting or a moment that requires silence, there is nothing worse than a phone that doesn’t stop ringing, with airplane mode you can prevent this happening and do it fast, because it activates in a second and deactivates all applications. At night it is especially useful to avoid notifications of social networks and other applications, but leave the alarm intact, to cite an example.
7. Use the Internet:
Very simple, activating the airplane mode and later the Wi-Fi connection. This way if someone call us, it will appear as off, but we can surf the internet, use social media, or chat in Whatsapp.
8. Recover Signal:
Useful on those sites with weak signal, such as basements, parking lots and subway stations. It is as simple as activating airplane mode, allowing a few seconds to pass, and deactivating it again and possibly stabilizing it.
9. Answer Whatsapp without updating your last connection:
This Trick is useful if we need to send a new message or answer a conversation without the rest of our contacts see our connection, we can activate the Airplane mode, then enter Whastapp and send the messages that we want (these will not be sent, are in the process of sending) . Then we exit the app and disable Airplane mode. So the messages will be sent but the last access to Whatsapp will not be registered.
Now, while there are so many functions, why do we continue to call this mode “airplane”?
Most airlines still forbid phone calls once the takeoff is announced. Flight attendants often warn that the use of electronic devices, including cell phones, could interfere with the operation of the aircraft. Phones that are turned on and in normal operation emit electromagnetic radiation that, according to regulations from several countries, could affect the navigation of the aircraft. In 2013 The US Federal Aviation Administration (FAA) determined that most commercial aircraft can tolerate interference signals from electronic devices.
The discussion on whether or not to allow passengers to make voice calls at heights was once again a topic recently.
The president of the Federal Communications Commission (FCC), Ajit Pai, recently rejected a proposal to allow telephone calls on planes. His predecessor, Thomas Wheeler, had argued that the ban was “obsolete” because many aircraft already use mobile signals as part of the Onboard Entertainment System (SEB). The FCC took the measure in 1991 because of concerns that numerous cell phones on flights could jam ground relay stations while planes were flying.
That is why in recent years the United States and Europe have relaxed their regulations on the use of electronic devices.
In addition to airplanes, there are other places where smartphones and mobile phones can cause interference with equipment installed on the same site (such as precision instruments), or are directly annoying with notifications and calls. Hospitals and laboratories are the most common sites, and in those cases, the best we can do is turn on airplane mode when we are told.
