The distance of each successive swath should be offset to allow the edges of neighboring swaths to overlap. What is this called?

• A. Effective Swath Width
• B. Even flat-fan pattern
• C. Droplet Spectrum
• D. Drift

Answer: (A)

The key idea is ensuring continuous field coverage by overlapping the sprayed areas from consecutive passes. When you offset each pass so the edges overlap, the actual width treated in one pass becomes larger than the nominal pattern due to that overlap. This real coverage width is called the effective swath width. It’s the measure you use to plan how many passes are needed to cover the whole area without gaps or excessive overlap.

The other terms don’t describe this coverage reality. An even flat-fan pattern refers to how evenly the spray spreads across the swath, not how much you offset passes. Droplet spectrum is about the sizes of the droplets, which affects drift and deposition but not the width of coverage. Drift is the movement of spray off target due to air movement, again not about the deliberate overlap between passes.
