Flying from Dortmund to Frankfurt in the FlyByWire Airbus A320 Neo in Microsoft Flight Simulator
An example end-to-end flight from Dortmund to Frankfurt in the FlyByWire A320 Neo in Microsoft Flight Simulator - illustrating navigation, alitutude control, and talking a little about procedures, and where you might communicate with ATC.
I regularly fly online with a group that simulate ATC with a group of perhaps 10 pilots with ground tower, departures, sectors, approach, handovers, and so on. It's great fun, and a great stepping stone to the likes of VATSIM, should you be interested in pursuing that. Search for "MyAir Virtual" in Google :)
