What constitutes a "small UAS" under federal regulations?

The definition of a "small UAS" under federal regulations specifically refers to unmanned aircraft systems that weigh less than 55 pounds, including their payload. This weight limit is significant because it encompasses a wide range of drone models that are typically used for commercial and recreational purposes. This regulation helps ensure safety in the national airspace by distinguishing smaller, less complex UAVs from larger aircraft that may be subject to stricter controls and regulations.

The weight criteria is established to manage potential risks associated with the operation of drones and to enforce requirements suited to their operational characteristics. By classifying UAS based on the 55-pound threshold, regulators can implement appropriate safety measures, training, and operational guidelines that are calibrated to the capabilities and risks of smaller drones.

The other options do not align with the regulatory definition of a small UAS. While the notion of a drone being carried by one person may align with certain smaller models, it is not the defining characteristic used by federal regulations. Likewise, defining a UAS solely on whether it is designed for recreational use or its operating environment, such as urban areas, does not incorporate the crucial factor of weight which is fundamental in distinguishing small UAS under the law.
