Actually CG, there will be a bone for Snarek's C airspace gripes.
From Stage 3 you get:
Characteristic 42 - Target resolution - Separation standard between IFR and VFR aircraft within Class A and B airspace.
This means ATC don't need a separation standard, just have to avoid scraping the edges of the radar symbols.
From Stage 4 you get:
Characteristic 14 - Class C dimensions - Class C airspace will consist of a 5NM radius core surface area that extends from surface up to 4,000 feet above the airport elevation, and a 10 NM radius step that extends from 1,200 feet to 4,000 feet above the airport elevation.
Characteristic 15 - Class C dimensions will have an upper limit consistent with the United States model.
Which both mean you could fly over MC without clearance at about 4500.
