“Unmanned Aerial Vehicle” (UAV) is used by industry interchangeably with UAS; however, the FAA has chosen under the newly published regulation 14 CFR part 89 to define the term “unmanned aircraft” (UA) as the aircraft itself, to distinguish the system from the aircraft. Industry’s UAV term and the FAA’s UA term are really just part of a UAS. Either term can refer to fixed wing UAs, which look like airplanes, or rotorcraft such as quadcopters or other multirotor aircraft. The term UAV is mostly associated with military aircraft, but can be used for a variety of other functions. UAV can also be semi-autonomous, meaning that the aircraft performs using sensors, a ground control system, and specific software programming.
