An aircraft pilot or aviator is a person who controls the flight of an aircraft by operating its directional flight controls. While other aircrew members such as navigators or flight engineers are also considered aviators, because they are involved in operating the aircraft  ́ s flight systems, they are not pilots and do not command a flight or aircraft. Other aircrew members such as flight attendants, mechanics and ground crew, are not classified as aviators.
