What is the legal definition of a small UAS according to the FAA?

The legal definition of a small Unmanned Aircraft System (UAS) according to the FAA is based on weight limitations. Specifically, the FAA defines a small UAS as an unmanned aircraft that weighs less than 55 pounds, including everything that is onboard or otherwise attached. This weight limit is significant because it classifies the type of regulations and operational guidelines that apply to the aircraft.

The distinction of 55 pounds is critical, as it helps ensure safety in populated areas and allows for a broader range of recreational and commercial use within the framework of FAA regulations. Understanding this definition is essential for compliant drone operation, as it influences factors such as registration requirements, operational airspace rules, and safety standards that UAS operators must follow.

In contrast, the other options either inaccurately represent the FAA's weight limits for small UAS or focus on different criteria such as wingspan or general characteristics of remote-controlled devices, which are not specifically part of the FAA's definition for this classification.
