In what scenario might Class G airspace increase to a higher ceiling than 1,200 feet AGL?

Class G airspace, commonly referred to as uncontrolled airspace, typically extends from the surface up to 1,200 feet above ground level (AGL). However, there are specific instances where the ceiling can exceed this standard limit. One such instance is where Class G airspace is explicitly depicted on sectional charts. These depictions can show variations in airspace classifications based on terrain or other regulatory considerations, indicating where Class G may extend beyond 1,200 feet AGL for safety and operational reasons.

For example, in certain areas, particularly where there is a need to manage airspace around airports or in regions with specific geographical features, charts will clearly define Class G airspace boundaries that allow for higher ceilings. Thus, referring to sectional charts is crucial for pilots to understand the actual airspace classifications as they may contain annotations or markings that highlight variations in ceiling limits.

In contrast, while mountainous terrain can affect flight operations and visibility, it does not automatically increase Class G airspace ceilings. Similarly, special VFR operations and nighttime operations deal with specific regulations for visibility and cloud clearance rather than the classification of airspace itself. Therefore, identifying specific areas on sectional charts that depict Class G airspace limits is vital for understanding where the ceiling may
