Windage refers to the effect of wind on the trajectory of a projectile, or the resistance created by the shape of an object as wind passes around it. This term is used in various contexts:

Shooting and Ballistics: In sports or military shooting, windage is the lateral adjustment of the sights of a rifle, or adjustments made to compensate for the effect of the wind on a bullet’s path.
Engineering and Architecture: In engineering, windage can refer to the drag or force exerted by wind on structures such as buildings, bridges, or vehicles. Engineers must consider windage to ensure structural stability and safety.
Sailing: In sailing, windage refers to the resistance of a boat’s above-water parts (such as masts, rigging, and hull shape) to the wind, which can affect its speed and direction.
