Eurocats in Australia
We currently get radar data on a separate monitor - useless, but will soon get it on screen as you describe Scott, with the same 10 minute update. Haven't seen it yet though.
Annotate (we call it text-on-screen or TXA for some strange reason. I think a lot of our acronyms have been badly translated from the french...) has been vital to cover the fundamentally stupid design of our system, a lot of worst of which (thankfully and finally) has been re-designed out of it. Used a lot now to record details of airspace releases, vertical limits of temporary airspace and levels of inbound coordinated traffic (no data blocks here untill they hit your screen.....)
System was originally delivered without it, we got it activated before we went live on the system. It wasn't safe without it.
