Which statement best describes Class G airspace?

Which statement best describes Class G airspace?

• A. It is controlled and requires ATC clearance for all operations
• B. It is uncontrolled and generally lacks mandatory separation services
• C. It is identical to Class E airspace
• D. It requires radar services for IFR

Answer: (B)

Class G airspace is the portion of airspace that operates without ATC control, meaning it’s uncontrolled and there’s no requirement for ATC to provide separation services for traffic there. Pilots can enter without ATC clearance or two-way radio contact, and pilots are responsible for seeing and avoiding other aircraft. This airspace typically sits below the base of the overlying controlled airspace (often up to around 700 or 1,200 feet AGL in many areas), with weather minimums that apply for Visual Flight Rules. Since there’s no mandatory ATC separation in this space, the defining idea is that it’s uncontrolled and lacks required separation services. The other statements describe controlled airspace or services that do not apply to Class G.
