What is the effect of varying the application speed without changing the flow volume during spraying?

Varying the application speed while maintaining the same flow volume during spraying can lead to uneven coverage. When the speed of the aircraft changes, the time that the pesticide or fertilizer spends in the air can be altered, affecting how it is distributed over the target area.

A slower speed may result in heavier application in certain spots because the product is released over the same area for a longer time, leading to potential over-spraying in those areas. Conversely, if the aircraft moves too quickly, there may not be enough time for the product to disperse adequately, resulting in under-application in other areas.

Uniform coverage is critical for the effectiveness of aerial applications, ensuring that the target area receives the appropriate dosage of the chemical. If coverage is uneven, it can lead to poor pest control or ineffective fertilization, which can affect crop yield and lead to environmental concerns. Thus, the impact of application speed is significant in maintaining the intended effectiveness of the spraying operation.
