If we are to believe the future plans , data link will make all this redundant , the next frequency will be automatically uploaded by ATC , and you just have to accept , the D/L will then send a message back that you have gone to the next frequency and another that will make your call sign pop up on a screen. You can even skip the Good morning and Good bye. You can even select the language you want the box to display.. No need to speak anymore... wonderful future
