When a passenger boardes or departs a plane, they will be asked to put their electronic devices in airplane mode (also known as offline profile), which can be easily operated from the settings menu. Is this warning needed and what if someone leaves it.
Although the myth that the device’s inner panel can be burned if activated is widespread, the main reason for creating this slogan is based on the notion that the phone’s emissions may be interrupted.
When this switch is implemented – on cell phones, notebooks, tablets and portable consoles – they are disconnected from the mobile network and can no longer connect to messages, calls or the Internet. It looks like the device is turned off.
When you access the installed applications, you will not be able to use any features that require an internet connection. Only data such as downloaded images, videos or offline music or movies can be used.
The name of this mode comes from restrictions that existed many years ago, which prevented the device from being used during flights, so manufacturers are designing this alternative.
However, nowadays it is also used for other purposes such as wanting to disconnect from everything while using certain functions of the mobile.
If requested from the cabin to place the device in airplane mode, the purpose is to limit possible difficulties in communicating with the control tower or some other device in the cabin. In other words, non-compliance with this slogan may affect these features.
Although essential airlines are protected from electromagnetic radiation emitted by mobile phones, communications between aircraft and air traffic controllers continue to use traditional radio, which is highly sensitive to external interference. Offline profile is especially relevant.
If this happens in any situation, such as landing or departure, which is the key stage of the flight, the entire aircraft, including passengers and crew, may be at risk as it is the moment when landing coordinates are given. .
What’s on WiFi
Unlike the GSM network, the signal of WiFi networks is very weak at its peak power (100 MW) and is not recorded to cause any inconvenience. For this reason, many airlines around the world offer WiFi connectivity on their flights. The only restriction is that this service cannot be used when the plane is taking off, landing or flying below ten thousand feet.
For this reason, at the end of 2014 the European Civil Aviation Organization (EASA) allowed the unlimited use of mobile phones at all stages of flight. Even if it is allowed, companies must comply with the verification that guarantees that the signals will not be interrupted.
But beyond the guidelines and changes of recent times, various regulatory agencies acknowledge that the need to use airplane mode on mobile devices remains in the hands of airlines.
