To account for the influence of prop wash on a 9' spray pattern, what is necessary?

To effectively account for the influence of prop wash on a 9-foot spray pattern, repositioning the nozzles on the spray boom is essential. The prop wash created by the aircraft's propeller can significantly affect how the spray is distributed, potentially causing uneven application of the pesticide.

Repositioning the nozzles allows the aerial applicator to optimize the spray pattern and ensure that the product is applied uniformly across the target area. This adjustment can help mitigate the impact of the turbulent air movement caused by the prop wash, which might otherwise disrupt the intended coverage of the spray.

The other choices do not address the primary concern of adjusting the spray pattern in response to the prop wash effectively. Increasing the speed of the aircraft may alter the drone and distribution dynamics but does not specifically tackle the issue of spray pattern integrity. Adjusting water temperature can influence the viscosity of the spray solution but is not a direct response to how prop wash affects the overall application. Lastly, using a different pesticide formulation could change application characteristics, but it does not directly manage the existing spray pattern influenced by prop wash.
