Anybody? Think of it like SquawkBox for FSX.
I've left those two statements up there because I think it needs to be explained about ATC actually works.
The big thing about ATC is a concept called the '[ame="http://en.wikipedia.org/wiki/Sterile_Cockpit_Rule"]sterile cockpit[/ame]'. ATC are trained to provide this. The key part of a sterile concept is silence. Yes, silence. Once 'clear to land' has been passed to the PF along with the weather there should be no more discussion on the flight deck, no idle chatter, nothing to detract the PF from the landing.
Only if something goes wrong or if the PF requests to be notified about something should the PNF speak up. Crew Resource management applies but otherwise there is silence.
Now, Watch a video of a shuttle landing. How much 'ATC' actually happens? Very little of course because the shuttle doesn't need a landing clearence. It has that when it's given the go for the deorbit burn. Airspace is cleared via a NOTAM and nothing will be allowed on the runway because the shuttle is committed.
From 150,000ft to touchdown very little is said to the crew - again, it's the sterile cockpit idea - the call outs are:
1. Take GPS
2. Take Air Data
3. Take Tacan
4. On energy, approaching the HAC, no change to winds or weather, you are go for nominal chute deploy. (or go for late chute sometimes)
5. On at the 180
6. On at the 90
That's it. From 150,000ft to the ground there are just six pieces of information transmitted from the ground to the crew of the shuttle. Six pieces of information that are not possible to send over teamspeak without some sort of link to the players orbiter session.
Finally, you'll notice that the crew of the shuttle don't listen to ATC, don't talk to ATC and don't care about ATC. They don't need to because once those OMS engines fire they are comitted to a landing. They don't have to conform to a traffic pattern and the area around KSC is reserved airspace.
It's even pointed out above that the ISS Audio is quiet. Yes, because it's not ATC! It's more ham radio with occasional requests for information.
