Most commonly, you hear the term drone used by the media and the military, and the term UAV used most frequently by the FAA. The words Drone and UAV mean the same thing and can be used interchangeably. Both are aerial devices that can fly with a human who controls them remotely or, in the most advanced cases, fly alone without any human intervention, such as the fixed-wing drone below, so called because of its straight side wings that don't move. A UAV is an unmanned aerial vehicle.
They can fly remotely, for example, with a remote control or tablet, or independently. So is the UAV a drone? Basically, it is. The two terms are often used interchangeably. According to the FAA, “drone” is the general colloquial term used for all remotely piloted aircraft.
The FAA adopted this industrial designation to describe any aircraft without a pilot on board, regardless of size, shape, or capacity. Under this general term there are several interchangeable terms (UAS, RPA or UAV). Others indicate categories, such as a first-person view or an airplane model, each with a slightly different use and connotation. By definition, every UAV is a drone because it stands for unmanned aerial vehicle.
However, not all drones are unmanned aerial vehicles because a UAV works in the air, while “drone” is a general definition. Meanwhile, a UAS is what makes a UAV work, since the UAV is actually just one component of the entire UAS. An unmanned aerial vehicle (UAV) is an aircraft that does not carry human passengers or pilots. Unmanned aerial vehicles, sometimes called drones, can be fully or partially autonomous, but are most often remotely controlled by a human pilot.
RAND research has contributed to the public debate about the use of drones for war and surveillance. An unmanned aerial vehicle (UAV), commonly known as a drone, is an aircraft without any human pilot, crew, or passengers on board. Unmanned aerial vehicles are a component of an unmanned aircraft system (UAS), which includes the addition of a ground controller and a communications system with the UAV. The flight of unmanned aerial vehicles can operate under the remote control of a human operator, such as remotely piloted aircraft (RPA), or with varying degrees of autonomy, such as autopilot assistance, up to fully autonomous aircraft that do not have human intervention.
The acronym UAV stands for unmanned aerial vehicle, which is very similar to what a drone is in terms of what the definition means. Meanwhile, a UAV is the shortest version of a drone in the sense that it only covers vehicles and unmanned aerial objects. A UAS or unmanned aircraft systems includes not only the UAV or the drone, but also the person on the ground who controls the flight and the installed system that connects both. Classification of UAVs by the army's unmanned aerial systems (UAS) according to the weight, maximum altitude and speed of the UAV component.
An unmanned aerial vehicle (UAV) is defined as a motorized aerial vehicle that does not carry a human operator, uses aerodynamic forces to lift the vehicle, can fly autonomously or be piloted remotely, can be disposable or retrievable, and can carry a lethal or non-lethal payload. The malicious use of unmanned aerial vehicles has led to the development of technologies against unmanned aerial systems (C-UAS). A similar term is an unmanned aerial vehicle (UAVS) system, a remotely piloted aerial vehicle (RPAV) and a remotely piloted aircraft system (RPAS). Basically, a UAV is anything that can fly from the air but is unmanned in the sense that it doesn't have a pilot to control it from the inside.
