Flight Instructors teach students to fly. In order to become a Flight Instructor you need a commercial certificate and instrument rating. You must also be able to demonstrate and explain basic principles of flight, aerial navigation, weather factors and flying regulations both on the ground and in the air. Flight Instructors demonstrate operation of aircraft and equipment in dual-controlled planes. CFIs observe solo flights and determine each students’ readiness to take examinations for licensed ratings. CFIs also assist advanced students in acquiring advanced ratings such as commercial, instrument, multi-engine, and air transport ratings.
