The top of Class G airspace at a given location is generally
- A.10,000 feet MSL everywhere
- B.the top of the nearest control tower
- C.the base of the overlying Class E airspace
Correct answer
C. the base of the overlying Class E airspace
Why
Class G fills the space below Class E, so its ceiling is the floor of the Class E above it, commonly 700 or 1,200 feet AGL. It does not extend to a uniform 10,000-foot ceiling.
