What defines the effective swath width in aerial application?

The effective swath width in aerial application is defined as the width of a single pass that includes overlaps from other passes. This concept is essential for accurate application because it considers not just the width of the area being sprayed but also the overlap that occurs when multiple passes are made to ensure even coverage and prevent gaps in pesticide application.

Effective swath width helps aerial applicators calculate how much area will be covered during a flight and assists in maximizing efficiency while minimizing the potential for pesticide drift or uneven application. It's a critical factor in planning the flight pattern and determining the total area that will receive treatment.

In contrast, the total area covered by one pass does not take into account any overlaps, which could lead to under or over-application. The maximum distance that the pesticide can drift refers to external factors affecting pesticide placement but doesn't define swath width directly, and the diameter of the spray droplet size is related to the behavior of the spray but does not help define the effective swath width itself.
