A rotating airport beacon shown on a sectional chart is noted as operating —

Why: FAA-CT-8080-2H Legend 1 ("Sectional Aeronautical Chart") notes: "Rotating airport beacon in operation Sunset to Sunrise."

• Overstates the legend's note as a 24-hour, every-airport claim; the legend specifically times beacon operation to sunset-to-sunrise, not continuous operation.
• Invents a weather-based trigger; the legend ties beacon operation to the time of day (sunset to sunrise), not to IFR conditions.
