What is preferred to have present at the application site during the operation?

Having a ground crew member present at the application site during aerial application operations is preferred for several important reasons. A ground crew member plays a crucial role in ensuring the safety and efficiency of the operation. They are typically responsible for monitoring environmental conditions, assisting with communication between the pilot and ground support, and handling any immediate on-site issues that may arise during the application.

The presence of a ground crew member enhances operational safety by keeping an eye on the area, ensuring that other personnel or vehicles are not intruding into the application zone, and can help in the event of an emergency response. They also have a better understanding of the specific site characteristics and can provide valuable input on factors such as wind direction or local wildlife, which can influence the application process.

While other roles like safety officers and environmental specialists are certainly valuable in broader operational contexts, their presence may not be as immediately crucial during the actual application. Hence, the choice of having a ground crew member prioritized reflects a focus on operational safety and efficiency.
