What is a key requirement for aircraft used in aerial pesticide application?

A key requirement for aircraft used in aerial pesticide application is that they must be able to lift, transport, and disperse pesticides safely. This functionality is crucial because the primary purpose of these aircraft is to deliver pesticides efficiently and effectively over large agricultural areas. The aircraft's design and performance must ensure that they can handle the weight of the pesticides, maintain stability during flight, and apply the chemicals in a manner that maximizes coverage while minimizing drift and environmental impact.

While equipment like GPS navigation systems can enhance operational efficiency and accuracy, it's not a fundamental requirement for the aircraft itself. Similarly, having designs exclusive to crop dusting may not necessarily apply to all aerial applicators, as some aircraft can serve multiple purposes. Contact with ground surfaces is not relevant to the function of delivering pesticides from the air, making it an impractical requirement in this context.
