A pilot license is an official certification that allows an individual to operate an aircraft. To obtain this license, a person must complete specific training, which includes both ground school and flight hours. They must also pass written and practical exams to demonstrate their knowledge and skills in flying. There are different types of pilot licenses, such as the Private Pilot License (PPL) and the Commercial Pilot License (CPL), each with varying requirements and privileges. A PPL allows individuals to fly for personal enjoyment, while a CPL enables them to be compensated for their flying services.
