What group does a UAS typically belong to if it operates below 3500 AGL and weighs between 21-55 lbs?

A UAS that operates below 3,500 feet above ground level (AGL) and weighs between 21 to 55 pounds typically falls into the second classification group, which is Group 2. This grouping is defined by specific operational parameters and weight limits established by regulatory guidelines.

Group 1 generally refers to the smallest UAS, which are those weighing less than 20 pounds and operating at lower altitudes, making them suitable for different applications typically involving minimal risk. Group 3 encompasses UAS that weigh between 56 pounds and 1,320 pounds and are capable of operating at higher altitudes and longer ranges. Group 4 is designated for larger UAS that exceed those weight limits and often have the capacity for more complex mission profiles.

By placing these specifications into context, it is clear that a UAS in the 21 to 55-pound range, when operating under 3,500 AGL, fits neatly within the parameters defined for Group 2, thus confirming the answer. This classification system helps in regulating UAS operations according to their capabilities and operational environments, ensuring safety and compliance with aviation regulations.
