To assist in overlap and coverage uniformity, passes should be made at what angle to the wind direction?

Making passes at a 45-degree angle to the wind direction is beneficial for several reasons related to aerial application practices. When the aircraft approaches the target area at this angle, it helps to reduce the negative effects of wind drift, ensuring that the pesticide or other materials are distributed more evenly across the intended treatment area.

This setup minimizes the likelihood of uneven coverage caused by crosswinds that can push droplets away from the desired area. Additionally, a 45-degree approach balances the effective overlap of spray patterns, enhancing coverage uniformity. By utilizing this angle, applicators can maintain better control over the spray and achieve more accurate applications while avoiding potential environmental contamination.

In contrast, other angles such as 30, 60, or 90 degrees could result in increased drift and uneven distribution patterns, which could be less effective and potentially harmful to adjacent areas or crops.
