The acronym UAS stands for which phrase?

• A. Unmanned Aerial System
• B. Unmanned Aircraft System
• C. Unmanned Airspace System
• D. Autonomous Aircraft System

Answer: (B)

UAS stands for Unmanned Aircraft System. The word Aircraft identifies the vehicle itself, while System emphasizes that this is a complete setup that includes the aircraft, the ground control station, and the data-links that connect them. This terminology focuses on the full configuration needed to operate the unmanned aircraft, not just the vehicle. The other phrases don’t match the standard meaning: Unmanned Aerial System uses a different word for the vehicle, Unmanned Airspace System would describe the airspace rather than the equipment, and Autonomous Aircraft System would imply inherent self-governance, which isn’t how UAS is defined—though some operations can be autonomous, the official term centers on the unmanned aircraft plus its supporting components.
