CHAPTER 8. The National Airspace System

Uncontrolled Airspace

Class G Airspace

Class G or uncontrolled airspace is the portion of the airspace that has not been designated as Class A, B, C, D, or E. Class G airspace extends from the surface to the base of controlled airspace (Class B, C, D, and E) above it as shown in Figures 8-2 and 8-3.

Most Class G airspace is overlaid with Class E airspace, beginning at either 700 or 1,200 feet above ground level (AGL). In remote areas of the United States, Class G airspace extends above 700 and 1,200 AGL to as high as 14,500 feet before the Class E airspace begins. [Figure 8-2] The pilot is advised to consult the appropriate sectional chart to ensure that he or she is aware of the airspace limits prior to fl ight in an unfamiliar area. [Figure 8-4]

There are no communications, entry, equipment, or minimum pilot certifi cate requirements to fl y in uncontrolled Class G airspace unless there is a control tower. [Figure 8-5]

If operations are conducted at an altitude of < 1,200 feet AGL, the pilot must remain clear of clouds. If the operations are conducted more than 1,200 feet AGL but less than 10,000 feet mean sea level (MSL), cloud clearances are 1,000 feet above, 500 feet below, and 2,000 feet horizontally from any cloud(s). A popular mnemonic tool used to remember basic cloud clearances is “C152,” a popular fi xed-wing training aircraft. In this case, the mnemonic recalls, “Clouds 1,000, 500, and 2,000.”

Visibility in Class G airspace below 10,000 MSL day fl ight is one statute mile (SM) for private pilots and three SM for sport pilots. See Figure 8-6 for specifi c Class G weather minimums for WSC pilots.
