What is a problem associated with flying too low during granule application?

Flying too low during granule application can create specific challenges, particularly related to the horizontal movement of the granules. When an aircraft is at a lower altitude, the granules can still retain their horizontal velocity, which means they might not land accurately in the targeted areas. Instead, they can drift and disperse unevenly due to wind or air turbulence, resulting in a less effective application. This lack of precision can lead to sections of the target area being over-applied or under-applied, thereby reducing the overall efficiency of the treatment and potentially causing environmental or regulatory issues.

Understanding this dynamic is crucial for aerial applicators; maintaining an appropriate flying height is essential for achieving optimal granule placement and ensuring the effectiveness of the application while minimizing waste and off-target movement.
