VC Required or not?

Does VC required for ATC communication? Or I can use chat? If yes, how? (xPilot)

Hello - What is a “VC”?

VC stand for voice chat.

You can use text chat. To do so, tune the frequency as usual and then instead of speaking, just type your messages in the chat box that encompasses the right two thirds or so of the client (you can type in the bar at the bottom).

However, keep in mind that voice is the preferred means of communication and if you are able to use voice, you should do so. If you are unable to use voice or don’t want to for some reason, try to use receive only instead. Working text is a lot of additional workload for ATC, especially in busy airspace, so when flying text only you might occasionally see some delay until ATC can get to you.
