Which of the following is true about Class G airspace?

Class G airspace is indeed known for its unique characteristics regarding operational control. This airspace is classified as uncontrolled, meaning it is not subject to the same air traffic control regulations and oversight as controlled airspace categories, such as Class A, B, C, and D. Pilots operating in Class G airspace are responsible for their own navigation and separation from other traffic without the direct assistance of air traffic control.

Class G airspace typically extends from the surface up to the base of the overlying Class E airspace, which emphasizes its function in accommodating various types of operations, including VFR (Visual Flight Rules) flights. This lack of specific operational control is part of why it is important for pilots operating in this airspace to maintain a heightened awareness of their surroundings and to follow basic FAA regulations to ensure safety.

The other statements do not accurately describe Class G airspace. It is not the same as Class A airspace, which is entirely controlled and requires specific IFR (Instrument Flight Rules) operations. Also, Class G is not the lowest class of controlled airspace, as it is an uncontrolled airspace. Finally, while all operations in airspace must comply with FAA regulations, this is a broad requirement that spans all classes of airspace
