Which of the following best describes the Group 3 UAS operational parameters?

The description of Group 3 UAS (Unmanned Aircraft Systems) operational parameters being "less than 1320 lbs, up to 18,000' AGL" is accurate based on the classification standards set by the Federal Aviation Administration (FAA) and other aviation regulatory bodies.

Group 3 UAS are typically defined by their weight and operational ceiling. The weight limit of 1320 lbs allows for a robust platform capable of carrying various payloads, including cameras and sensors, while still ensuring it fits within regulations for operational safety. The operational ceiling of up to 18,000 feet AGL (Above Ground Level) is significant because it enables these UAS to operate in varied environments, including light airspace that may be used by manned aircraft.

This classification accommodates a variety of missions ranging from surveillance to agricultural monitoring, thus highlighting the versatility that UAS in this category can offer. The parameters ensure that operators understand the capabilities and constraints of their devices when planning missions.

In contrast, other options either exceed the standard operating classifications or do not align with the established limits for Group 3 UAS.
