Class D
Two-way radio communication must be established before you enter, while the tower is open.
The same callsign rule as Class C. When the tower closes the airspace usually reverts to Class E, or to Class G where no surface area is charted — the Chart Supplement entry says which, and the hours are on the sectional. A surface area normally extends to 2,500 ft above the field, with the ceiling charted in a dashed blue box as a number in hundreds of feet.
