Flying at higher altitudes can result in which of the following?

Flying at higher altitudes can lead to an increased risk of drift primarily because of the environmental conditions that change with altitude. At higher elevations, wind speeds can be greater, and the density of the air is different, which can cause pesticide droplets to be carried away from the target area. This can lead to unintentional application to non-target areas, including nearby crops, water bodies, or residential areas.

Additionally, the physical characteristics of the spray being used, such as droplet size and weight, interact differently with the wind when released from a higher altitude, which can exacerbate the drift issue. Therefore, operating at higher altitudes necessitates careful consideration of these factors to minimize the risk of drift during aerial applications.
