hey we are law students participating in an international law moot court competition. We happen to have a case identical to that of the ueberlingen collision (same facts just made up countries and services) and we are so lost in all the terminology about ATC and TCAS and STCA etc etc. If someone could help us out with a few clarifications it would be greatly appreciated. One more thing, what is the difference between ATM and ATC? I mean, does ATC fall into the sphere of ATM? Cause we are reading the ESARRs and they keep talking about ATM while in our case the company that is like skyguide was providing ATC services? Thank you so much all in advance and anyone who could possibly help and is willing to, are welcome to send us a private message
