The daylight operation of the rotating beacon indicates weather below basic VFR minimums at airports located in which airspace class?

• A. Class D
• B. Class B
• C. Class C
• D. Class E

Answer: (A)

Rotating beacons used in daylight on certain airports are a visual cue about weather conditions relative to VFR minimums. When you see the beacon operating during daylight at an airport that lies within Class D airspace, it indicates that the weather at that airport is below the basic VFR minimums. This serves as a clear signal to pilots that VFR flight conditions are not met there, and IFR procedures or additional planning may be necessary for safe operation. This specific daylight signaling is tied to airports in Class D airspace, whereas beacons don’t convey the same weather-minimum warning in Class B, Class C, or Class E airspace.
