Which application pattern is recommended to avoid flying through spray from a previously applied swath?

The race track pattern is recommended to avoid flying through spray from a previously applied swath due to its design, which involves flying parallel to the direction of the application. This configuration allows the aerial applicator to maintain a consistent flight path without re-entering the area that has already been treated, thus minimizing the risk of overlap and potential drift from the earlier passes.

In a race track pattern, the aircraft makes a continuous loop around the field, enabling efficient coverage while ensuring that newly applied chemical does not come into contact with spray from prior applications. This is particularly important not only for the effectiveness of the treatment but also for environmental safety and compliance with application regulations.

Other patterns, such as the circle or diagonal patterns, might require the pilot to cross over previously treated areas, increasing the likelihood of flying through leftover spray. The figure-eight pattern, while useful for certain types of flying maneuvers, can also lead to overlaps unless executed with specific care, making it less efficient for avoiding already treated swaths. Therefore, the race track pattern stands out as the most effective choice for maintaining application integrity and safety.
