A Certified Flight Instructor (CFI) is a professional pilot who has received certification to teach others how to fly. This certification is granted by the Federal Aviation Administration (FAA) in the United States and requires passing written, oral, and flight tests. CFIs play a crucial role in training new pilots, helping them develop the skills and knowledge needed to operate an aircraft safely. CFIs can teach various types of flight training, including private pilot, instrument rating, and commercial pilot courses. They also provide valuable guidance on aviation regulations, flight maneuvers, and safety procedures. Many aspiring pilots seek out CFIs to gain the experience required for their own certifications.
