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

During a granule application, flying too low primarily impacts the horizontal movement of the granules. When the aircraft is at a lower altitude, the granules are subjected to less drop distance and greater influence from the aircraft’s forward speed. This dynamic can lead to difficulties in achieving the desired distribution pattern across the target area since the granules may not have enough time to settle properly or may be affected by the lift generated by the aircraft.

In essence, the effectiveness of the application can be compromised as the granules may not reach the targeted location in the intended manner, resulting in uneven coverage or possibly even missing the target altogether.

Factors like granules scattering, visibility, and the risk of crop damage are certainly relevant considerations when applying, but the fundamental reason why flying too low is problematic centers on how the granules behave in relation to the aircraft's height and speed. The optimal altitude supports accurate dispersal and effectiveness of the application.
