What happens when airspeed is increased without changing the spray output?

When airspeed is increased while keeping the spray output constant, the volume of pesticide delivered per unit area decreases. This is because, although you are still applying the same total amount of pesticide, it is being dispersed over a larger area due to the higher speed of flight. As the aircraft moves faster, the spray is spread out over greater distances, resulting in less pesticide actually hitting each individual acre. Thus, the effective application rate decreases, leading to a lower concentration of pesticide per acre.

This concept is crucial for aerial applicators to understand as it directly impacts the effectiveness of pest control and crop protection. If the active ingredient is diluted by covering more land, it may not achieve the desired effect, which is why managing airspeed in relation to output is vital for effective aerial application.
