Which of the following is a common sign of nozzle wear in aerial application?

A common sign of nozzle wear in aerial application is an inconsistent spray pattern. When nozzles wear out, their ability to disperse the liquid evenly can be compromised, leading to variations in droplet size and distribution. This inconsistency can affect the efficacy of the application, as it may result in areas being over-treated or under-treated, which can impact pest control or crop health.

Increased fuel consumption, reduced engine power, and excessive noise levels are not typically direct indicators of nozzle wear. While these factors could indicate other mechanical issues with the aircraft or application equipment, they do not specifically point to nozzle functionality. Therefore, recognizing changes in the spray pattern is crucial for maintaining effective aerial application practices and ensuring that the intended amount of substance is applied uniformly across the treatment area.
