The flag symbol at Lake Drummond represents what?

• A. Visual checkpoint used to identify position for initial callup to Norfolk Approach control
• B. VOR station
• C. Holding pattern boundary
• D. IFR approach corridor boundary

Answer: (A)

On sectional charts, a flag symbol marks a VFR checkpoint—a fixed reporting point you can identify to determine your position and know when to contact ATC. The flag at Lake Drummond designates your location for the initial call to Norfolk Approach control, so you know when to establish radio contact as you enter or move through that airspace.

This symbol isn’t a VOR station, which would be shown as a navigation aid symbol, nor does it depict a holding pattern boundary or an IFR approach corridor boundary, which are shown with different chart symbols. The flag’s purpose is specifically to provide a visual reference point for ATC communications.
