To "become a pilot" means to undergo the necessary training, education and experience requirements to become qualified as an airplane or helicopter pilot, and to obtain the necessary licenses or certifications from regulatory authorities. The process typically involves learning the principles of aerodynamics, navigation, weather forecasting and aircraft systems, as well as gaining practical experience through flight training and supervised flying. Once a pilot has completed the necessary training and meets all regulatory requirements, they are considered to be qualified and authorized to operate an aircraft as a pilot.
