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

When airspeed is increased without changing the spray output, the amount of active ingredient applied per acre is reduced. This is because the same volume of spray is being dispersed over a larger area due to the faster flight speed. As the aircraft travels more quickly, it effectively passes over more ground in the same time interval, leading to a lower concentration of pesticide being applied to each unit area. This change can impact the efficacy of the application since the target plants may not receive enough of the active ingredient for effective pest control. Understanding this dynamic is crucial for ensuring that the desired level of pest management is achieved when conducting aerial applications.
