   • A.Surface to 10,000 ft MSL
   • B.18,000 ft MSL up to and including FL600
   • C.FL180 up to FL450
   • D.Surface to 60,000 ft MSL
   Show answer & explanation

   Answer: B. 18,000 ft MSL up to and including FL600

5. Question 5

   Class D airspace typically extends to how high above the primary airport?

   • A.1,500 ft AGL
   • B.2,500 ft above airport elevation
   • C.4,000 ft above airport elevation
   • D.10,000 ft MSL
   Show answer & explanation

   Answer: B. 2,500 ft above airport elevation
