Frequently Asked Questions
What are the two CFI knowledge tests?
To become a CFI, you must pass two FAA knowledge tests: 1) Fundamentals of Instruction (FOI) - 50 questions covering learning theory, teaching methods, and evaluation techniques. 2) Flight Instructor Airplane (FIA) - 100 questions covering aerodynamics, aircraft systems, flight maneuvers, regulations, weather, and flight planning. Both tests require a 70% passing score.
What is the CFI exam pass rate?
The combined CFI knowledge test pass rate is estimated at 65-75% for first-time test-takers. The FOI exam tests instructional concepts that are new to most pilots, while the FIA covers technical aviation knowledge at the commercial pilot level. With thorough preparation using 200+ practice questions and understanding both teaching theory and aviation concepts, you can improve your chances of passing on the first attempt.
How many questions are on the CFI exams?
There are two CFI knowledge tests totaling 150 questions: 1) FOI (Fundamentals of Instruction) has 50 questions - you need 35 correct (70%) to pass. 2) FIA (Flight Instructor Airplane) has 100 questions - you need 70 correct (70%) to pass. You have approximately 2.5 hours for FOI and 3 hours for FIA.
How long should I study for the CFI exams?
Plan for 60-80 hours of dedicated study over 4-6 weeks. Allocate about 20-25 hours for FOI (learning theory, teaching methods) and 40-55 hours for FIA (technical aviation knowledge). Review the Aviation Instructor's Handbook, Airplane Flying Handbook, Pilot's Handbook of Aeronautical Knowledge, and complete at least 200 practice questions. Aim for 80%+ consistently on practice tests before scheduling.
What are the requirements to become a CFI?
To become a CFI you need: 1) Hold a commercial pilot certificate or ATP certificate, 2) Hold an instrument rating (for airplane category), 3) Be at least 18 years old, 4) Be able to read, speak, write, and understand English, 5) Pass two knowledge tests (FOI and FIA), 6) Pass a practical test (checkride) with a DPE or FAA inspector.
