In recent years, the terms ‘Unmanned Aircraft System’ (UAS) and ‘drone’ have often been used interchangeably in media, industry, and regulatory discussions, leading to some confusion regarding their definitions and implications. This article aims to clarify these terms and explore their relationship, usage, and regulatory contexts.
Firstly, it’s important to understand what each term stands for. UAS, or Unmanned Aircraft System, refers to the entire system used to operate an unmanned aerial vehicle (UAV). This system includes not only the UAV itself but also the ground-based controller and the communication system used to control the UAV. The term emphasizes the complete set of equipment necessary for operation, not just the aircraft.
On the other hand, the term ‘drone’ is a colloquial expression that originated from earlier remote-controlled aircraft used for target practice by the military. Today, ‘drone’ is commonly used to describe any remotely piloted or autonomous vehicle, which can be aerial, terrestrial, or marine. In the context of aerial vehicles, a drone typically refers to any UAV, which could be as simple as a hobbyistâs remote-controlled aircraft or as complex as a high-tech surveillance and targeting UAV used by the military.
Given this broader usage, all UAS can be considered drones if they are aerial in nature because they involve unmanned, remote, or autonomously piloted aircraft. However, not all drones are UAS. For example, a consumer drone bought for recreational photography does not necessarily constitute a UAS unless it includes sophisticated systems for navigation and control, designed for more than basic flight operations.
The distinction becomes even more significant in regulatory terms. Various international and national bodies, including the Federal Aviation Administration (FAA) in the United States, use the term UAS specifically because it highlights the inclusion of support and control systems beyond the aircraft. Regulations regarding UAS are not merely about the aircraft but encompass the entire operation, including the pilot’s qualifications, the aircraft’s certification, and the communication systems used.
In practical terms, when discussing regulations, privacy concerns, or airspace integration, using the term UAS is preferable and more accurate. It conveys the complexity and breadth of what is being regulated. For hobbyists and the general public, the term ‘drone’ might suffice to describe what they operate, but for professionals in the industry or regulators, the distinction provided by ‘UAS’ is crucial.
Moreover, the term UAS is also indicative of a shift towards more integrated, networked systems in unmanned aircraft technology. These systems can include autonomous decision-making capabilities, advanced human-machine interfacing, and operations beyond line-of-sight. Such capabilities are transforming what started as simple remotely controlled aircraft into sophisticated systems that require comprehensive regulatory frameworks.
In conclusion, while it’s accurate to refer to a UAS as a type of drone, understanding the nuances between these terms is important, especially for those involved in regulation, operation, or industry discussions. The term UAS captures the full scope of equipment and operational considerations and is fundamental in discussions that pertain to legality, safety, and integration of these technologies into national airspace systems. As the technology and applications of unmanned aircraft continue to evolve, so too will the terminology and regulatory landscape surrounding them.
