During the flight, the aircraft relies on the infinite signal contact with the ground to ensure the route. The mobile phone will radiate electromagnetic signals during the call, and the server status will keep in touch with the ground base station with strong continuity. Using a mobile phone will interfere with the communication between the plane and the ground. Of course, when the plane is flying at high altitude, the mobile phone can't receive the signal.

However, in the process of taking off and landing, the interference of mobile phone signals to navigation system will have quite serious consequences. A slight deviation can ruin a person's life.
