A windsock that is solid color indicates an airport that is ______.

A windsock that is solid color indicates an airport that is ______.

• A. not certified
• B. certified
• C. under construction
• D. closed

Answer: (A)

A solid-colored windsock communicates that the airfield is not certified for public use. In practice, windsock color coding is used as a quick way to signal the airport’s certification status: a solid color means the field does not meet the requirements to operate as a public-use airport, so pilots should not rely on it for standard public operations. If the airport were certified and open, you’d expect the normal windsock signals and the field to be considered available for public use. An airport under construction or closed would typically show other indicators (barricades, NOTAMs, or a windsock removed) rather than relying on a solid color alone to convey status.
