VFR on top

Why would this be?

Forgive me for looking at this from the Euro POV, but it is true that
if outside CAS one can fly anywhere one likes if VFR, whereas if IFR
one is supposed to fly on ATS routes (published airways).

However, there are countries (e.g. Greece) where *all* traffic (incl.
VFR) is supposed to be on airway routes, and one can also get DCT
clearances when IFR.

Moreover, I can be flying VFR in CAS (say Class C) and be talking to
some IFR (approach or departure) ATC unit, and they will be watching
me (with a Mode C squawk) and in effect separating me and other
traffic, occassionally giving me vectors. This is VFR, but it makes
perfect sense.

So I can't see why ATC would allow more routing leeway if VFR than if
IFR. Does the minimum separation change?


Yes, aircraft operating VFR-on-top are treated as VFR aircraft for
separation purposes.
