Ah....never bothered reading that as it dont make much sense to me! Does that mean you can only fly VFR on top with an IMC? Didnt think it mattered once you were up there....only how you got there.
Will delve into the boring green book when I'm back at work......if I can find someone to translate it as I'm a bit fick!!!
Just found that bit on-line.
So that means you can fly VFR on top of, in theory, up to BKN cloud with 3000m visibility, as long as you stay near the 1 okta you can see the surface through.
I realise reality is not quite as simple as that!
