A flight instructor is a trained professional who teaches individuals how to fly aircraft. They provide both ground school instruction, covering aviation theory and regulations, and in-flight training, where students practice flying under supervision. Flight instructors help students prepare for their pilot licenses, ensuring they understand safety protocols and operational procedures. To become a flight instructor, one typically needs to hold a valid pilot's license, such as a Private Pilot License (PPL) or Commercial Pilot License (CPL), along with a Certified Flight Instructor (CFI) rating. This role is essential in the aviation industry, as it helps develop skilled pilots who can operate various types of aircraft safely.
