The innermost ring with a radius of typically extends from the surface area around the airport to AGL (above ground level; charted in MSL), and an outer ring, with a radius of that typically surrounds the inner ring and extends from a floor at AGL, (also charted in MSL), to the ceiling at AGL, (again charted in MSL). These dimensions are sometimes highly customized when deemed necessary to accommodate IFR traffic patterns and other surrounding airspace design issues such as the overlapping or close proximities to other classes of airspace.
