Hi FL1,
Thanks for the reply.
I think you are right. I’ve looked up a few ATZ’s that I know have ATC like Inverness, Humberside and Exeter and they are also all class G.
I’ve been reading CAP 1535 - the latest Skyway code - and it mentions SVFR in an aerodrome traffic zone so this is slightly ambiguous but I’ll take it as SVFR is for CTR’s only and not ATZ’s.
Here is the extract for CAP 1535 - Skyway code.
A VFR flight may not take-off or land
at an aerodrome within a control zone (CTR), or enter the aerodrome traffic zone or circuit when the reported conditions
at that aerodrome are less than:
> cloud ceiling of 1500 ft; or
> ground visibility of 5 km.
This applies regardless of the CTR’s airspace classification. If these conditions are not met, you may request a Special VFR clearance instead.
