I am stumped by how to use ATC with FS2crew. The manual says use the default as the FO will not do it for you, but the dafault gives a different call sign and initial altitude. And it speaks over other messages. How does one work it?

Hi,You just manage. People talking over each other... that's realistic in a sense.FS2Crew does not interconnect with the default MS ATC system, so if you set your callsign in FS2Crew 747 to Speedbird, for example, you would need to manually set your ATC callsign in FS to Speedbird as well.Same sort of thing with the initial altitude (I assume you're referring to the altitude briefed for in the SID).Frankly, the default MS ATC isn't that great... If you want good ATC I recommend VATSIM/IVAO or Radar Contact.Cheers,Bryan
