The lateral dimensions of Class D airspace are based on

A

the number of airports that lie within the Class D airspace.

B

5 statute miles from the geographical center of the primary airport.

C

the instrument procedures for which the controlled airspace is established.✓ Correct Answer

Explanation

AIM 3-2-5 states that the lateral dimensions of Class D airspace are based on the instrument procedures for which the controlled airspace is established, so the shape and size vary from airport to airport. It is not a fixed 5-mile circle, and it does not depend on how many airports lie within it.
