If this feature gets added, it would be a game changer.
Voice ATC like vatsim would be a great update with pilots that have more knowledge with radio communication and at the right age. But If you want to have access to voice atc they must take a certain exam in order to get that access, but players below 12 shouldn't have access since they need to learn more. But before entering this voice atc there will be like a lecture they'll read to learn more knowledge about ATC communication, Not just the exam but more resources for the game. Such as an airport diagram, SIDs and STARs charts, ground charts etc. That's all!
