Flight instructors are authorized to provide flight instruction to pilots and pilots requiring additional certificates/ratings. Flight Instructors also complete flight review for license revalidation and recommend flight tests for students. As a CFI, you must be at least 18 years of age, and hold a valid commercial pilot certificate & IFR rating.
Aside from their standard flight review every 24 months, CFI’s must also revalidate their instruction certification every 24 months. You may not instruct without a CFI rating.
