Calibration in aerial spraying is important because vortices can change what?

• A. Toxicity of chemicals
• B. Application rates
• C. Tank mixing order
• D. Spray droplet size

Answer: (B)

When spraying from air, the moving aircraft creates swirling air patterns that can disrupt the spray plume. These vortices can cause the amount of chemical that actually deposits on the ground to vary across the treated area. Calibration is the process of determining the real ground rate your system delivers under your exact flight conditions (speed, altitude, nozzle type, pressure). Because those vortices can change how much chemical ends up per unit area, calibration helps ensure you apply the intended rate, not more or less than planned. The other options don’t address the need to match the actual deposited amount per area under turbulent conditions.
