Class D airspace is generally cylindrical in form and normally extends from the surface to 2,500 feet (760 m) above the ground. Airspace within the given radius, but in surrounding class C or class B airspace, is excluded. Class D airspace reverts to class E or G during hours when the tower is closed, or under other special conditions. [9]

Class B airspace corresponds to the area formerly known as a Terminal Control Area or TCA. [6] Class C airspace reaches from the surface to 4,000 ft. AGL above the airport which it surrounds.
