Wot you are saying, if I may paraphrase, is that to fly to the legal limits of JAA VFR (3km) you need to be instrument capable.
Never mind flying to the limits of ICAO VFR: 1.5km.
And I agree
It's a fine line.
If flying was invented today, I doubt we would have the rather artificial distinction between VFR and IFR - because technology makes it so blurred. Of course, if flying was invented today, the H&S crowd would instantly ban it...
I think SV is wonderful for IFR, for a pilot/passenger (PNF) monitoring when you are flying your IAP into say Sion. But... you can achieve this using say X-Plane with NMEA input, running on any old windoze box with a bluetooth GPS. For £ 3 figures. And it will be just as accurate, though probably without obstacle data.
