What is the upper limit of the vertical extent of Academy Class D Airspace?

• A. 2,500 feet MSL
• B. 2,700 feet MSL
• C. 3,000 feet MSL
• D. 3,200 feet MSL

Answer: (D)

Class D airspace is the controlled airspace around a towered airport, starting at the surface and extending up to a published ceiling. That ceiling is shown on aeronautical charts in MSL. For the Academy, the published ceiling of its Class D is 3,200 feet MSL, so the airspace from the surface up to 3,200 feet MSL is Class D. Above that, the airspace transitions to the next class (typically Class E) unless another designation applies. So 3,200 feet MSL is the altitude where this particular Class D ends and the next class begins, which is why that option is correct.
