What is a critical step for aerial applicators before flight?

Performing a pre-flight inspection of the aircraft is essential for aerial applicators before taking to the skies. This thorough assessment ensures that all systems and components of the aircraft are functioning properly and that the aircraft is safe for flight. The inspection typically involves checking the condition of the wings, control surfaces, fuel levels, and any other critical systems.

By conducting a pre-flight inspection, aerial applicators can identify potential issues that could compromise safety and performance during the application process. This proactivity not only helps avoid accidents but also enhances the effectiveness of spraying operations. Safety is paramount in aviation, and this inspection is a fundamental step in preparing for a successful flight.

While other options involve important aspects of preparing for flight—such as checking equipment or weather reports—they do not have the comprehensive safety focus that a pre-flight inspection provides. Calibrating the aircraft's speed might be part of operational readiness but is secondary to ensuring the overall airworthiness of the aircraft.
