Why are electronic devices put on airplane mode on a flight?

According to FAA guidelines, the Federal Communications Commission (FCC) and Federal Aviation Administration (FAA) prohibit the use of cell phones during flight due to the potential interference with crucial aircraft instruments. Passengers are required to utilise airplane mode or disable cellular connections on their devices. However, if the airplane is equipped with a WiFi system approved for passenger use by the airline, passengers may access WiFi on their devices while in flight.
