Aircraft that weigh less than 55 pounds are classified as what?

The classification of aircraft that weigh less than 55 pounds as small unmanned aircraft systems (sUAS) is based on regulations set forth by aviation authorities, such as the Federal Aviation Administration (FAA). These regulations define a small unmanned aircraft system as any unmanned aircraft weighing less than 55 pounds, which typically includes a range of drone types used for various purposes, such as recreational flying, aerial photography, surveying, and more.

This classification is important because it outlines specific operational guidelines and regulations for the safe and legal use of these aircraft in airspace. By identifying sUAS under this weight threshold, authorities can establish rules that ensure safety while accommodating the growing interest and use of drones in both commercial and recreational contexts.

In contrast, kites and hot air balloons do not fit within the same regulatory framework as sUAS, as they operate under different principles of flight or are subject to different rules due to their unique characteristics and uses. The option regarding SAC is likely irrelevant in this context, as it does not pertain to the classification of small aircraft by weight. Thus, recognizing less than 55-pound aircraft as small unmanned aircraft systems aligns with established aviation guidelines and practices.
