Unless there are no changes during the flight, like runway switch, everything works somehow. But since the ATC does not use any STARs etc. you are pretty much pwned.
So I wasted a couple of hours with that ATC and I decided to switch it off until we have something that is not based on 30 year old code.
Talking about standard altitudes and stuff. Speed and ALT restrictions. Etc. The data is there. They just need to find a genius coder for it.
