A Flight Instructor teaches students to fly an aircraft utilizing in-class instruction, a flight simulator, and through test airplane flights. Flight Instructors train students on the physics of aerodynamics, how to manage the navigation and emergency systems, and provide pre- and post-flight checklists. The training process also covers radio procedures and includes practice flights. Flight Instructors are certified pilots themselves, often with hundreds or thousands of hours of flight time, and must remain current on all training and requirements.
