Why do we have to put the cell phones in flight mode on the plane’s take-off?

One of the usual instructions to passengers during the aeroplane’s take-off is to put them into flight mode. When we activate the flight mode, mobile phones are disconnected from mobile networks. CORVERSE In a video published on Tik Tok, a pilot (@PerchPoint) explained why it is important to put our devices in the specific configuration that exists on all modern smartphones. First, the pilot specifies that if you forget to put your phone in flight mode, the end of the world will not come, since the plane will not fall from the sky, but will not cause any trouble in the aircraft systems. However, he points out that in case even a small number of passengers (3 or 4 persons) on a flight with 70, 80, 150 people want to talk on their cell phone and answer incoming calls, then radio waves are created due to the connection to the radio tower. ADVERSE Continuing, the pilot says that “there is a possibility that these radio waves may cause interference in the radio waves of the headphones used by pilots”. The more ya know, Yanno? The pilot cited a typical example during a take-off from San Francisco where, in his attempt to hear instructions and important messages from the control tower, his headphones were caused by interference. In fact, the pilot likened the annoying hum to the noise caused by mosquitoes and wasps.
