How can the influence of prop wash on spray pattern be accommodated?

Repositioning the nozzles on the spray boom is the most effective way to accommodate the influence of prop wash on the spray pattern. Prop wash, which is the air movement caused by the aircraft's propeller or rotor system, can distort the intended spray pattern by causing drift or uneven distribution of the chemical being applied. By repositioning the nozzles, aerial applicators can better align them with the airflow dynamics created by the prop wash, ensuring that the spray is applied uniformly across the target area. This adjustment can help in minimizing drift and ensuring the product is applied where it is most needed, leading to more effective treatment of the area being sprayed.

While regulating the output flow, adjusting the aircraft speed, or decreasing the pump speed may impact the overall application process, these measures do not specifically counteract the effects of prop wash on the spray pattern as effectively as repositioning the nozzles.
