Please tell me the purpose of the flight mode on my phone

pu1. The airplane boarding mode is a function that is used when boarding a plane, and it is a function that can easily block communication functions. The reason why this function is needed is because the radio waves used in mobile phones can affect the devices needed to control and operate the aircraft, so it is necessary to turn off the function on the plane. It's complicated to turn off that function every day, so you can turn off your phone or simply turn it off in airplane mode
