The airspace from the surface to 10,000 ft Mean Sea Level (MSL) surrounding the nation's busiest airports in terms of IFR operations or passenger enplanements. The shape of each Class B airspace area is unique and consists of a surface area and two or more layers (some Class B airspace looks like an upside down wedding cake) it's designed to contain all published instrument procedures once an aircraft enters the airspace.
