What does the abbreviation "sUA" represent in aviation terms?

The abbreviation "sUA" stands for "Small Unmanned Aircraft." In aviation, this classification refers specifically to unmanned aerial vehicles that weigh less than 55 pounds and are designed for operations that include recreational use, commercial purposes, and various applications like aerial photography and surveying. Understanding this term is crucial for drone operators and anyone interested in the regulatory environment surrounding drone use, as it determines the operational standards and regulations that apply to these aircraft.

The other terms listed, while they may have relevant meanings within different contexts of aviation or technology, do not accurately describe the specific category of unmanned aircraft defined by regulatory bodies such as the FAA. Recognizing "sUA" as Small Unmanned Aircraft helps distinguish this particular type of aircraft from others in discussions around airspace management, safety, and certification requirements.
