FAA sectional chart excerpt for this question — Sectional: Miami, edition effective Sep 3, 2026 (next edition Oct 29, 2026). Source: FAA (public domain).

Refer to the marked airport. What are the vertical limits of the Class D airspace at MIAMI-OPA LOCKA EXEC (OPF)?

A. From the surface up to and including 2,500 ft MSL
B. From the surface up to and including 2,500 ft AGL
C. From 2,500 ft MSL up to 10,000 ft MSL

Answer: A. Inside the dashed blue Class D circle you'll find a number in a box: [25]. It gives the ceiling in hundreds of feet MSL, so this Class D goes from the surface to 2,500 ft MSL. Field elevation is 8 ft MSL, so the Class D extends about 2,492 ft above the airport. Chart altitudes for airspace are MSL unless marked AGL.
