Which airspace class is uncontrolled?

• A. Class A
• B. Class B
• C. Class G
• D. Class E

Answer: (C)

Uncontrolled airspace means there is no air traffic control service or mandatory ATC clearance in that airspace; pilots must rely on see-and-avoid and local procedures to stay safe. The airspace class that fits this description is Class G. It typically extends from the surface up to the base of the overlying controlled airspace (which is usually higher up, where Class E or another controlled class begins). In Class G, weather minima and the level of airspace management are less stringent for VFR flights, reflecting the absence of ATC separation services. All other classes are controlled, with ATC providing services and, in many cases, required clearances for entering or operating under certain conditions.
