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

In recognition of the pilots' qualifications and responsibilities, most militaries and many airlines worldwide award aviator badges to their pilots, as well as other air crews. This includes naval aviators.
