Yep , do not believe the Press releases or read them very carefully . most claims are just trials , like the last one in Saarbruecken by DFS/Frequentis . 5 days ..
Norway is AFIS not ATC , etc...
That said the thing is coming , and big time. Half of the CANSO/ATC exhibition in Madrid last week was about Remote ATS ( yes not only TWRs, but APPs and small ACCs will be next )
Multiple OPS is the big issue, will be difficult to sell to us , but they will get there one day because without it there is no business case. Cost benefit is only showing with multiple simultaneous OPS. not just one to one remote unit. More expensive.
The thing that will slow this down the timescale is not Controllers but the current stable availability and cost of High speed data transfer on secure lines.
Last nail in the coffin : ICAO just announced that one hurdle on DOC4444 . ( the visual acquisition bit) was cleared. "visual " can now also be via a display.
