What helicopter handling signal is indicated by a horizontal cutting motion across the throat during fueling operations?

The horizontal cutting motion across the throat is a signal commonly used to indicate that fueling operations should be ceased immediately. This gesture is universally recognized in aviation operations and serves as a visual command to stop any ongoing activities, such as fueling, to prevent potential hazards associated with fueling operations, including fire or spillage.

In the context of helicopter handling, it is vital for personnel to have clear and distinct signals to ensure safety and effective communication during fueling, which is a critical and potentially dangerous operation. Recognizing this signal allows crew members to respond swiftly, thus enhancing safety protocols and mitigating risks during helicopter servicing. This proficiency in hand signals is essential for all members involved in ground operations, particularly in dynamic environments where verbal communication may be compromised or difficult.
