How should an aircraft be managed when changing nozzle booms or other variables?

When changing nozzle booms or making adjustments to other application variables, recalibrating and conducting pattern tests on the aircraft are essential steps to ensure effective and safe pesticide application. This process involves measuring and adjusting the flow rate of the nozzles to maintain the correct application rate, which helps to avoid over-application or under-application of pesticides.

Recalibration ensures that the changes made do not adversely affect the aircraft's ability to distribute the pesticide uniformly. Pattern testing further verifies that the spray pattern is consistent and that the pesticide is being applied at the correct height and width, which is crucial for achieving the desired coverage and minimizing drift.

While repainting or retrofitting with new equipment may be necessary in different contexts, they do not directly relate to the immediate adjustments needed for proper pesticide application following changes in equipment. Therefore, recalibrating and pattern testing is the appropriate and necessary action to take when changing nozzle configurations or other operational variables, ensuring compliance with safety standards and enhancing the effectiveness of the aerial application.
