How is the presence of an airport beacon indicated on a chart?

The presence of an airport beacon on a chart is indicated by a star above the airport symbol. This notation serves as a visual cue for pilots, allowing them to easily identify locations equipped with beacons that aid in navigation, particularly at night or in low-visibility conditions. The star signifies that the beacon is operational and enhances situational awareness for pilots flying in the vicinity of the airport.

The other markings on charts serve different purposes. A square around the airport symbol typically signifies a different class of airport or a specific type of operational status, while a circle generally represents a visual waypoint or area of interest but not specifically an airport beacon. Dashed lines may denote various airspace boundaries or restrictions but do not pertain to the indication of an airport beacon. Understanding these symbols is essential for safely navigating and operating in the airspace around airports.
