You mean SVFR of course being a Class A zone...and yes we do have SVFR traffic.
As I said, the Aeromed light twins often take SVFR.
As for the short pattern stuff, that is what we do with SVFR traffic, normally holding abeam a 5 mile final. However, this then blocks the Helicopter routes.
The biggest problem with light traffic is the face that if it arrives amongst a lod of heavies it has to have 7nm vortex and a larger gap behind because of the lower speeds.
