Traffic operating under VFR must be in communication with a controller before entering the airspace. The airspace is similar to Class B's "upside-down wedding cake", but much smaller and simpler. The innermost ring typically extends from the surface area around the airport to AGL, with a radius of ; and an outer ring typically surrounds the inner ring and extends from a floor at AGL, to the ceiling at AGL, with a radius of ; these dimensions are sometimes highly customized when deemed necessary by taking into account surrounding airspace design.
