What is the purpose of using a "check pilot" during aerial applications?

The role of a "check pilot" is primarily centered on safety and ensuring that the operation adheres to established operational standards. This involves oversight and evaluation of the aerial application processes, verifying that all protocols are followed properly. The check pilot plays a crucial role in assessing the performance of the pilot and the equipment, ensuring that the application of chemicals is conducted safely and effectively. This oversight helps prevent accidents and enhances the overall safety of the aerial operations.

Options related to monitoring fuel usage, handling communication with ground crews, or managing navigational equipment, while significant in their own right, do not encompass the primary purpose of the check pilot's role. The check pilot’s focus is on the safety and compliance aspects, which are essential for maintaining operational integrity in aerial applications.
