How is the inspection of wind cones evaluated?

The evaluation of wind cones primarily focuses on their physical condition and functionality. A wind cone must not be frayed and should swing freely to accurately indicate wind direction and speed. If the fabric of the wind cone is damaged or frayed, it cannot perform its function effectively, which is to display the wind's movement. Additionally, if the wind cone is not able to swing freely, it may not respond to changes in wind direction, leading to unreliable visual guidance for pilots.

The other options do not address the essential criteria for a wind cone's performance. Placement at extreme ends of the runway can be important, but it doesn't relate to the condition or functionality required for an accurate wind indication. Bright neon colors might enhance visibility in certain contexts, but they are not a standard requirement for the evaluation of effectiveness in a wind cone. Lastly, the visibility of wind cones primarily relates to daytime conditions, as they are expected to provide real-time guidance regardless of the time of day. Thus, the condition ensuring they are functional for pilots' use is paramount.
