Can I use my mobile phone by plane?

The mobile phone on the plane can be used after the "flight mode" is turned on

When using a mobile phone in the air, you need to pay attention to the following points:

1. When using the mobile phone in the air, you must set the mobile phone to flight mode and turn off the mobile communication function.

2. Mobile phones and other devices that do not have flight mode are still prohibited from being used in the air.

The origin of flight mode:

In flight mode, the communication module of the mobile phone is closed, so that the mobile phone can't answer the phone and send short messages, and there is no signal contact with the base station. At this time, calculator, stopwatch, clock and other functions can be used. This is a state of "anti-interference" and the original meaning of "flight mode", which means that the mobile phone is not disturbed like flying. But on the other hand, it doesn't mean that the mobile phone won't interfere with the take-off and landing of the plane.

There are indications that the so-called "flight mode" is just a function that manufacturers unilaterally add to mobile phones in order to please consumers. Although this mode can provide users with some conveniences such as anti-jamming under certain circumstances, it should be noted that this function has not been recognized by the aviation department, and it is still illegal for passengers to use "flight mode" without turning off their mobile phones when flying.

At present, almost all airlines do not allow passengers to put their mobile phones in the "flight mode" state on the plane. From closing the hatch when the plane takes off to opening the hatch on the ground, the power of the mobile phone must be turned off. The "flight mode" state of the mobile phone will also affect and interfere with the communication system between the cockpit and the ground tower, which has potential safety hazards.
