Airspace not Class A, Class B, Class C, or Class D, and is controlled airspace is which class?

• A. Class G
• B. Class E
• C. Class B
• D. Class A

Answer: (B)

Controlled airspace that isn’t A, B, C, or D is Class E. This category fills the spaces between the tightly defined, airport-centric classes and the truly uncontrolled airspace. It remains under ATC jurisdiction, but it isn’t the specific, tightly bound environment of A, B, C, or D.

Class E commonly begins at either 700 feet or 1,200 feet above the ground in most areas and extends upward to but not including 18,000 feet MSL, where Class A begins. There are also portions that begin at the surface in special areas, but in any case it’s still considered controlled airspace. By contrast, Class G is uncontrolled airspace, existing where air traffic control doesn’t have jurisdiction, and the other classes (A through D) refer to those particular, well-defined, airport-centered or high-altitude environments.

So, the airspace described is Class E.
