What is an advantage of an electronic sprayer volume controller?

An electronic sprayer volume controller is particularly advantageous because it can adjust the spray output in response to changes in airspeed. As the aircraft travels at varying speeds, maintaining a consistent application rate of the pesticide is crucial for effective coverage and efficacy. If the aircraft speeds up, the volume controller compensates by reducing the output, ensuring that the same amount of product is applied per unit area. Conversely, when the aircraft slows down, the controller increases the output to maintain that necessary coverage. This dynamic adjustment not only improves application accuracy but also helps in minimizing waste and environmental impact.

Other options provided do not accurately describe the functions of an electronic sprayer volume controller. For instance, the altitude of the aircraft is controlled by other avionics systems, not by the volume controller. Similarly, while temperature can influence pesticide performance and behavior, measuring it is not a function of the volume controller. Lastly, enhancing visibility of the spray pattern is more related to nozzle design and application techniques rather than a capability of the electronic volume controller itself.
