It's all coming back to me now - the reasons I hated airlaw so much!
From the above therefore do I correctly conclude that at night with a plain vanilla PPL plus night badge, I can fly to the Channel Isle (ClassA airspace) and would be IFR to the zone boundary and svfr from there on, and would have to remain vmc with 10k viz, and that with my IMC I can fly in cloud all the way to the zone boundary IFR but from the zone boundary I would need vmc and 3k viz?
