Uncontrolled Airspace
What is uncontrolled airspace?
Uncontrolled airspace, also called Class G airspace, is the portion of airspace that has not been designated as Class A, B, C, D, or E. It extends from the surface up to the base of the overlying Class E airspace, and air traffic control does not provide separation services to aircraft operating there. Think of it as the "leftover" airspace—wherever the controlled classes aren't, Class G fills in from the ground up.
Also known as: Class G, Class G airspace
