What is Class G airspace?

What is Class G airspace?

• A. A Controlled Airspace Requiring ATC Clearance
• B. A Type of Airspace for Medical Helicopters
• C. An Area Where ATC Provides Radar Services
• D. Uncontrolled Airspace

Answer: (D)

Uncontrolled airspace. Class G is the portion of the sky where ATC does not provide separation services and pilots operate without ATC clearance. In the United States it runs from the surface up to the base of the overlying Class E airspace (base heights vary, commonly at 700 or 1200 feet AGL). Because there’s no mandatory ATC control here, pilots rely on see-and-avoid and follow basic VFR weather minimums. You can still request services like traffic advisories or flight following from ATC, but clearance is not required. The other descriptions don’t fit Class G: it isn’t controlled airspace requiring ATC clearance, it isn’t limited to medical helicopters, and it isn’t defined as a radar-service area.
