Which statement about Class G airspace is true?

Which statement about Class G airspace is true?

• A. It is controlled and requires ATC clearance for all operations
• B. It is uncontrolled and generally lacks mandatory separation services
• C. It is identical to Class E airspace
• D. It requires radar services for IFR

Answer: (B)

Class G airspace is the portion of the sky that is not controlled by ATC. It’s considered uncontrolled, so there are no mandatory separation services provided by air traffic control for flight within it, and pilots don’t need ATC clearance to operate there. This is why the statement describing Class G as uncontrolled and generally lacking mandatory separation services is true. Class G sits from the surface up to the base of the overlying controlled airspace (typically Class E, which begins at a certain altitude depending on the area). The other descriptions would imply it’s a controlled environment or require radar or explicit clearances, which isn’t how Class G works.
