Windcone: The Essential Visual Guide for Aviation Wind Assessment
In the dynamic world of aviation operations, the windcone (or windsock) remains one of the most reliable and universally recognized wind indicators. These simple yet effective devices provide pilots with immediate visual information about wind direction and speed, playing a critical role in safe takeoffs, landings, and ground operations. As aviation technology advances, the humble windcone continues to maintain its fundamental importance at airports, helipads, and industrial sites worldwide.
