Seems that the UK class G is actually class F if surveillance is available.
From UK Flight Information Services CAP774 (
https://publicapps.caa.co.uk/docs/33...74Issue2_3.pdf)
"1.4 ... The conditions for the provision of deconfliction in Class G airspace and ATS in Class E airspace are predicated on flight rules. Deconfliction Service and Procedural Service are only available to flights in Class G airspace operating under IFR."
followed by
"Deconfliction
"4.7 A controller shall provide traffic information, accompanied with a heading and/or level aimed at achieving a planned deconfliction minima against all observed aircraft in:
Class G airspace;
..."
As I see it, it means that the VFR in G don't hear, or care about, ATC vectoring the IFR out of their way.
