Flight Instructor Written Exam Prep Coming Soon
AviaSkill is building AI-powered preparation for both FAA Flight Instructor Knowledge Tests — the Fundamentals of Instruction (FOI) and the Flight Instructor Airplane (FIA). Two exams, 14 ACS knowledge areas, and the same study tools you trust for PPL and IFR.

What are the FAA Flight Instructor Knowledge Tests?
Becoming a Certified Flight Instructor (CFI) requires passing two separate written exams — unlike PPL, IFR, or CPL which each have one.
Fundamentals of Instruction (FOI): This exam tests your knowledge of teaching and learning principles — how people learn, effective instructing techniques, assessment methods, and human factors in flight training. It's not about flying; it's about teaching.
Flight Instructor Airplane (FIA): This exam tests your technical aviation knowledge at an instructor level — deeper than the Commercial Pilot exam, covering all the material you'll need to teach student pilots. Think of it as a comprehensive review of everything from PPL through CPL, plus spin awareness and instructor responsibilities.
Together, these two exams ensure you're prepared to both fly and teach effectively. The CFI is one of the most common paths for building flight hours toward an airline career, and many pilots find that teaching makes them significantly better aviators.
Two Exams — Here's What to Expect
Fundamentals of Instruction (FOI)
Waived if you hold a current ground instructor certificate (BGI, AGI, or IGI)
Flight Instructor Airplane (FIA)
| Prerequisites | Commercial Pilot Certificate (or equivalent) |
| CFR Reference | 14 CFR 61.183–61.215 |
| Medical Required | Yes (to exercise CFI privileges) |
| Test Validity | 24 calendar months (2 years) |
| Recurrency | 24 months — renew via flight review, FIRC, or practical test |
14 ACS Knowledge Areas
The CFI ACS covers both teaching principles (FOI) and comprehensive aviation knowledge (FIA).
FOI Areas (Areas I–II)
Fundamentals of Instructing
The learning process, human behavior, effective communication, teaching methods, assessment and critique, instructor responsibilities
Technical Subject Areas
Aeromedical factors, visual scanning, runway incursion avoidance, principles of flight — from an instructor's teaching perspective
FIA Areas (Areas III–XIV)
Preflight Preparation
Teaching students about pilot qualifications, airworthiness, weather, flight planning
Preflight Lesson on a Maneuver
How to brief students before in-flight maneuver practice — lesson planning and delivery
Preflight Procedures
Preflight assessment, flight deck management, engine starting — teaching the correct procedures
Airport and Seaplane Base Operations
Teaching airport communications, traffic patterns, runway incursion avoidance
Takeoffs, Landings, and Go-Arounds
Teaching normal, crosswind, short/soft field, and go-around procedures
Fundamentals of Flight
Teaching the four forces, stability, turns, climbs, descents — foundational aerodynamics
Performance Maneuvers
Teaching steep turns, chandelles, lazy eights — instructor demonstrations and common student errors
Ground Reference Maneuvers
Teaching rectangular course, turns around a point, S-turns — wind correction fundamentals
Slow Flight, Stalls, and Spins
Teaching slow flight, power-on/off stalls, spin awareness and recovery — critical safety instruction
Basic Instrument Maneuvers
Teaching instrument scan, straight-and-level, turns, climbs, descents by reference to instruments
Emergency Operations
Teaching emergency approaches, equipment malfunctions, and decision-making under pressure
Postflight Procedures
Teaching after-landing, parking, securing, and post-flight debrief techniques
Your Path to Flight Instructor
Prerequisites
- A Commercial Pilot Certificate (or be concurrently training for one)
- A current third-class medical certificate (or higher)
- English proficiency
- FOI may be waived with a current ground instructor certificate
