What is the nature of Class G airspace?

Class G airspace is defined as uncontrolled airspace that exists from the surface up to the base of the overlying Class E airspace. It is typically found in areas where air traffic control does not regulate operations, making it more flexible for pilots, including those flying unmanned aerial vehicles, to operate without the constraints found in controlled airspace.

This classification is beneficial for general aviation pilots as it allows for less stringent regulations while maintaining safety standards. As Class G airspace is often used for activities like sightseeing and recreational flying, it facilitates easier access for pilots who do not need to communicate with air traffic control.

While Class G airspace may exist below Class E, it is important to note that it is not classified as controlled airspace; instead, it falls under the category of uncontrolled airspace. The other answer choices describe characteristics that do not align with the nature of Class G airspace. For instance, it is not highly restricted or permanent, and while it exists below Class E, its most defining trait is its uncontrolled nature.
