What is the maximum altitude for Class G airspace?

• A. 1,200 feet AGL
• B. No specified upper limit
• C. Flight levels up to 24,000 feet
• D. 10,000 feet MSL

Answer: (B)

Class G airspace is unique among the different classes of airspace in that it does not have a specified upper limit. This class of airspace is defined as uncontrolled airspace, typically found at lower altitudes, where pilots operate without the requirement to communicate with air traffic control. In the United States, Class G airspace usually extends from the surface up to 1,200 feet above ground level (AGL) in most areas. However, it can be found extending higher in certain regions or in different circumstances. The critical point is that there is no defined ceiling for Class G airspace, which means it can extend up to airspace where it then meets Class E airspace, which starts at 1,200 feet AGL or higher, depending on the area. Other choices presented might suggest specific altitudes or limits, but they do not accurately define the nature of Class G airspace as it stands. Understanding that Class G airspace lacks a defined upper altitude limit is essential for visual flight rules (VFR) operations, as it impacts how pilots navigate and understand their spatial distribution in relation to controlled airspace.
