How is Class G airspace generally identified on a sectional?

Class G airspace, also known as uncontrolled airspace, is generally identified on a sectional chart by the absence of specific markings. It extends from the ground up to a designated altitude, which is typically 1,200 feet above ground level (AGL) in most areas. This lack of markings indicates that there are no controlled airspace restrictions in that area for pilots operating under visual flight rules (VFR).

The absence of any shading or borders shows that pilots can operate freely without the requirements of avoidance or permission that are present in controlled airspace. Understanding this identification helps pilots navigate without confusion, ensuring they know when they are entering uncontrolled airspace and can adjust their flight duties accordingly.
