Which of the following describes Class G airspace?

Class G airspace, commonly referred to as uncontrolled airspace, is primarily found beneath Class E airspace or above the surface up to the base of the overlying Class E. This airspace does not have the same separation responsibilities that are found in controlled airspace, making it accessible for both visual flight rules (VFR) and instrument flight rules (IFR) operations, albeit with fewer regulations and requirements.

This relationship with Class E airspace is crucial: Class G airspace exists primarily below the designated lower limit of Class E airspace, which typically starts at either 700 or 1,200 feet above ground level. Knowledge of this delineation is vital for pilots navigating or operating within varied altitude layers during flight operations. Understanding the characteristics of Class G airspace helps ensure pilots comply with appropriate operational requirements based on their flight plan and the airspace they are flying through.
