How do I use it? Using xPilot
You just listen on voice and you reply by text. Nothing more to it. Make sure that you select the correct communication method/voice capability when filing your VATSIM flightplan - this way your flight tag will appear with the respective piece information on the radar screen of ATCOs and they know that they can talk to you, but that you will reply by text only. Unless you have a good reason for this (defective microphone, unable to make noise/talk because of other people around you etc.), please always use full voice. If you are new to online flying and you are afraid to talk, just jump into it and talk, make mistakes, it is normal. Otherwise you won’t learn it that fast.
