BTW, completely agree with BDIONU, gather requirements for a new ATC system from ScACC and LACC and you would find that you need two completely different systems!!!! So, coming up with a common platform will not be easy! Even at LACC, if you get 5 controllers in a room and say "what do you think of this then?" you will get a minimum of 5 different answers..... Always been the same, will never change.
