The ATPL (Airline Transport Pilot License) is the highest level of pilot certification. It is required for pilots to operate commercial airliners as captains. To get an ATPL, you need to complete significant flight training, including a minimum of 1,500 flight hours, pass written exams on subjects like navigation and meteorology, and meet strict medical standards. ATPL holders can fly internationally and are eligible for well-paying positions in commercial aviation. It’s a long and challenging process, but it opens doors to exciting career opportunities in the airline industry.
