eli5: If passengers are required to put their phones on airplane mode when flying, how, if at all, will the upcoming EAS system effect flights?

Question

To explain further, I have found mixed answers as to whether or not phones in airplane mode or that are shut off will receive the upcoming EAS. If they will receive it, will that impact the flight at all?

Even though EAS is broadcast it still requires your phone to establish a two way connection to a cellular network. No connection in airplane mode — no EAS broadcast is going to be received. The reason it requires a two way connection is simply because cellular networks and phones never supported a one way connection and the designers didn’t want to add that kind of mode just for this feature.
