To distinguish UAVs from missiles, a UAV is defined as a "powered, aerial vehicle that does not carry a human operator, uses aerodynamic forces to provide vehicle lift, can fly autonomously or be piloted remotely, can be expendable or recoverable, and can carry a lethal or nonlethal payload".[5] Therefore, cruise missiles are not considered UAVs because, like many other guided missiles, the vehicle itself is a weapon that is not reused, though it is also unmanned and in some cases remotely guided. The key feature which differentiates drone UAVs from radio-controlled aircraft is the presence of an autopilot capable of autonomous flight; a radio-controlled aircraft becomes a drone with the addition of an autopilot AI, and ceases to be a drone when the AI is removed.[6]
Many different names are used for these aircraft. They are unpiloted aerial vehicle (UAV), remote piloted aircraft system (RPAS), and model aircraft. It has also become popular to incorrectly refer to them as drones.[citation needed] Their flight is controlled either autonomously by onboard computers or by the remote control of a pilot on the ground or in another vehicle.
The term unmanned aircraft system (UAS) emphasizes the importance of other elements beyond an aircraft itself. The term UAS was since adopted by the United States Department of Defense (DoD) and the British Civil Aviation Authority. The term used previously for unmanned aircraft system was unmanned-aircraft vehicle system (UAVS). A UAS includes ground stations and other elements besides the actual aircraft. A typical UAS consists of:
unmanned aircraft (UA)
control system, such as ground control station (GCS)
control link, a specialized datalink
other related support equipment
The term UAS was first officially used by the FAA in early 2005 and subsequently adopted by DoD that same year in their Unmanned Aircraft System Roadmap 2005–2030.[7] The official acronym UAS is also used by the International Civil Aviation Organization and other government aviation regulatory organizations.
