Why is the term "Unmanned Aircraft System" preferred over UAV or drone?

The term "Unmanned Aircraft System" (UAS) is preferred because it encompasses all components that make up the system, not just the flying vehicle. This includes the aircraft itself, the control systems, the ground control stations, and the communication links between them. Recognizing and referring to the complete system underscores the complexity and multifaceted nature of unmanned aircraft operations, which require coordination among various elements to function effectively and safely. This holistic view is essential for proper regulation, safety protocols, and operational procedures in the field of unmanned aviation.

In contrast, focusing solely on the flying vehicle would ignore the significant roles that ground control and communication systems play in the successful operation of unmanned aircraft. Such a narrow definition would also not adequately address the responsibilities and considerations involved in operating the entire system, which includes aspects such as airspace management, regulatory compliance, and the integration of these systems into the broader aviation environment.
