What does the daylight rotating beacon indicate about weather in a Class D area?

• A. That weather at the airport located in class D airspace is below basic VFR weather minimums
• B. That the beacon is on during daylight hours only
• C. That weather is above basic VFR weather minimums
• D. That the beacon is malfunctioning and should not be trusted

Answer: (A)

In Class D airspace, basic VFR weather minimums apply: typically 3 statute miles of visibility and must remain clear of clouds. When conditions are below these VFR minima, the daylight rotating beacon at the airport is interpreted as signaling that poorer weather is present in the area. This helps pilots understand that VFR flight in that vicinity may not be possible and that IFR or SVFR operations are appropriate instead. The other options don’t reflect how the beacon relates to weather: choosing daylight operation vs night, or suggesting the beacon signals above-minima conditions or a malfunction, aren’t aligned with that weather signal concept.
