Class D airspace surrounds airports with what type of control facility?

• A. A local ATCT
• B. TRACON
• C. No control facility
• D. Regional control center

Answer: (A)

Class D airspace is designated around airports that have an operating control tower on the field. The defining facility is the local Air Traffic Control Tower (ATCT) on the airport itself, which provides control for aircraft on the ground and in the surrounding airspace. This is different from TRACON, which handles approach and departure sequencing in larger radar-controlled areas, and from the regional control centers that manage en route air traffic. Uncontrolled airfields have no on-site control facility, so they’re not Class D. When operating in Class D, you must establish two-way radio communication with the tower before entering and maintain that contact while inside.
