What aerial limit defines Class G airspace?

Class G airspace is defined as uncontrolled airspace that extends from the surface up to 1200 feet Above Ground Level (AGL). This type of airspace is prevalent in areas where air traffic control services are not actively managing aircraft movements, allowing pilots more autonomy. The 1200 feet AGL limit forms a buffer zone between Class G airspace and the overlying controlled airspace, which typically begins at 1200 feet AGL or higher, depending on the specific airspace classification in that region.

By understanding this aerial limit, pilots can better navigate during their flights, particularly when transitioning from uncontrolled to controlled airspace, ensuring they comply with air traffic rules and avoid potential conflicts with other aircraft operating in nearby controlled zones. This knowledge is essential for safe and effective flight operations, particularly in varying geographic regions where airspace classifications may change.
