BEX;
Sounds like the problem we had a bunch of years ago when we abandoned AAS (ISSS) and finally put together DSR. Not the best in Human factors, but it was all that the FAA was going to spend money on. So with begrudging controller input, we put together something that at least works. It's is by no means where it should be, or what it could be. But we are finally making small improvements to it as well as working on different types of functionallity that will plug into it...
