Why can't I make a phone call on the plane?

If you use a mobile phone to talk on the plane, it will cause great hidden dangers to the flight safety of the plane. For flight safety, you can't make a phone call on the plane.

The existing mobile phone communication needs a base station for the mobile communication system to transmit signals, but now the aircraft cabin is not equipped with complete supporting equipment.

If you don't turn off your phone or answer the phone directly, you need your mobile phone to find the most powerful base station.

This will easily lead to some abnormal mobile phones producing interference signals harmful to the aircraft.

The communication and navigation system on the plane is very sensitive to receiving signals hundreds of kilometers away.

Even the slightest interference will have a great impact on flight safety.

Technically speaking, mobile phones will not interfere with the communication between aircraft and ground and airborne antennas, but may affect the ranging and navigation equipment on board.

So for the sake of flight safety, it is forbidden to make phone calls on the plane.
