It is 'observation', but not in the traditional sense. I am taken with the idea of having traffic I'm managing from a traditional or virtual VCR labelled with flight callsign and height readout. Having seen some in-service systems and others demonstrated at ATS events, the only thing that I might be slightly uncertain about is managing the visual circuit, especially if the virtual VCR is not wrap around 360° . If you just have instrument arrivals and departures, a combination of the ATM, SMR, and virtual reality in a location that is not necessarily a traditional VCR could be good, especially if it closer to the airport confectionery outlet, or even in your spare bedroom at home and a resilient broadband service...... oh
