What is the primary purpose of calibration in aerial application?

Calibration in aerial application primarily focuses on ensuring that the correct amount of pesticide is applied to the target area. This process involves adjusting the application equipment to deliver the right volume of product at the right rate to achieve effective pest control while minimizing waste and environmental impact. Accurate calibration is essential for achieving optimal results, as applying too little may not effectively control pests, while applying too much can lead to pesticide drift, environmental contamination, and increased costs.

Other aspects such as adjusting the height of the aircraft, improving flight speed, or changing the nozzle type may enhance the efficiency or effectiveness of the application, but they do not primarily relate to the core function of calibration. Calibration specifically targets the precision of the amount of pesticide being dispersed, which is critical for both efficacy and safety in aerial application practices.
