UAV (unmanned aerial vehicle) refers to the aircraft itself. UAS (unmanned aircraft system) refers to the whole system — the aircraft, the controller, and the communications link between them. “Drone” is the informal, catch-all term the public uses for both. In everyday conversation the three are interchangeable. In regulatory and technical documents, UAS is the term you’ll actually see the FAA use.
What does UAV stand for?
UAV stands for unmanned aerial vehicle: any aircraft that flies without a pilot physically on board. It can be remotely piloted by a human operator or fly a pre-programmed autonomous route. The term describes the aircraft itself, not the ground equipment or software around it.
What’s the difference between a UAV and a UAS?
A UAS — unmanned aircraft system — is the broader term. It covers the aircraft (the UAV), the ground control station or remote controller, and the data link connecting them, treated as one system. The FAA uses UAS as its standard regulatory term for exactly this reason: a drone flight involves more than just the aircraft, and UAS captures the whole operational picture.
In practice, most people use UAV and UAS interchangeably, and outside of regulatory documents, that’s rarely a meaningful problem.
Is “drone” a different thing from a UAV?
No. “Drone” is the informal, everyday term for the same aircraft a technical document would call a UAV. The word’s origins are military: early unmanned aircraft used for target practice were compared to male bees, which do little but fly around a hive. That connotation is largely gone now. “Drone” is simply the term the general public reaches for, while government agencies, manufacturers, and technical publications tend to use UAV or UAS.
How does the FAA classify drones by weight?
US drone regulation is built around weight thresholds. Aircraft weighing less than 250 grams (0.55 lbs) don’t require registration for recreational flying, though registering is still recommended. Aircraft between 250 grams and 25 kilograms (55 lbs) must be registered and flown either under Part 107 commercial rules or recreational rules that include passing the TRUST safety test — this range covers the overwhelming majority of consumer and commercial drones. Aircraft over 55 lbs need a special airworthiness certification or an FAA exemption, since they fall outside the “small unmanned aircraft system” (sUAS) category entirely.
Does the distinction actually matter?
For casual conversation, no. UAV, UAS, and drone all point at the same aircraft, and using any of them will be understood. The distinction starts to matter in two places: reading FAA regulations, where UAS is the term that actually appears in the rule text, and in military and industrial contexts, where UAV specifically emphasizes the aircraft as a platform, separate from the ground systems and personnel operating it.
