FAA Flight Instructor Instrument Airplane (FII), Instrument Airplane Added Rating (AIF) and Ground Instructor Instrument (IGI) knowledge tests
The instrument instructor knowledge tests — FII for your CFII, AIF for the added rating and IGI for the instrument ground instructor — built on the instrument knowledge you'll teach.
About the exam
A flight instructor instrument rating (CFII) lets you give the flight and ground training for an instrument rating and the instrument proficiency check; an instrument ground instructor rating lets you give instrument ground training, the ground portion of an IPC and the recommendation for the instrument knowledge test (61.215(c)). Three FAA knowledge tests lead there, and all three draw on the same instrument knowledge: FII (Flight Instructor Instrument — Airplane), AIF (the shorter added-rating version, which the FAA allows only if you already hold a flight instructor certificate) and IGI (Ground Instructor Instrument).
FII and IGI each have 50 multiple-choice questions in 2 hours 30 minutes; AIF has 20 questions in 1 hour. Every question has three answer choices, and you need 70% to pass. The tests are taken on computer at a PSI test center with a photo ID and an FAA Tracking Number (FTN) from IACRA; the testing matrix lists no instructor endorsement for a first attempt and a minimum testing age of 16. Approach plates, en route charts and weather products come from the FAA testing supplement handed to you at the center. Fundamentals of Instructing (FOI) is a separate test — you need it for your first flight or ground instructor certificate unless you already hold one, hold a state teaching certificate for grade 7 or higher, or teach at an accredited college or university (61.183(e), 61.213(b)). For FII and AIF, a passing result is valid for 24 calendar months for the practical test.
Our practice covers every area with original questions mapped to the instrument ACS and the instrument instructor standards, with step-by-step worked solutions for every calculation — holding-pattern entries, descent rates for a glide path, climb gradients, IFR fuel and alternate requirements, VOR check tolerances and wind correction. Add flashcards for IFR regulations, endorsements and minimums, worked case walkthroughs of student scenarios and approach plates, illustrated guides to instruments and navigation displays, and timed practice tests at the FII length — 50 questions in 2 hours 30 minutes — with a score. IGI is the same length; if you're taking AIF, aim to finish the full test comfortably inside the time.

Questions built on the ACS
Every question is original and tagged to an instrument knowledge area or instructor task — three choices like the real test, with approach plates and en route charts described in text, holding-pattern diagrams, IFR weather reports and student-error scenarios.
Hints and worked solutions
Reveal the rule, reference or formula behind the question when you're stuck. Every answer has the full rationale, and every calculation is solved step by step.
Adaptive practice
Questions steer toward your weakest areas, weighted like the real test, and get harder as you get stronger.
Timed practice tests
Full-length tests at the real pace — 50 questions in 2 hours 30 minutes, the FII and IGI length — with a pacing indicator, full review and a percent score against the 70% pass mark.
Flashcards, walkthroughs and guides
Flashcards for IFR regulations, instrument endorsements, minimums and weather codes, worked case walkthroughs that reason through harder questions step by step, and interactive illustrated guides you explore hotspot by hotspot.
Progress in every area
Each area moves from Not started to Exam ready, so you know exactly what to study next.
Radio & callouts drill
Copy IFR clearances by ear, read back holds, approach clearances and amended routings, and handle lost-comm and emergencies — the same spoken scenarios your instrument students will fly.
Test at home or at a center
FII, AIF and IGI are scheduled and taken through PSI, the FAA's knowledge-testing provider. Create a profile in IACRA to get your FAA Tracking Number (FTN), confirm which of the three tests applies to you, then choose a PSI test center and time. Remote testing is not offered for FAA airman knowledge tests.
At a PSI test center
- Book through PSI's FAA scheduling site; the fee is paid to PSI, not the FAA — about $175 at PSI (confirm when you book).
- Bring a current government-issued photo ID that meets FAA identification rules, and your FAA Tracking Number (FTN).
- The center gives you the FAA testing supplement with the approach plates, en route charts and weather figures; some questions show images on screen.
- You may use an FAA-approved flight computer (E6B) and calculator under the test center's rules; PSI's testing system also includes an on-screen E6B.
Before you book
- Pick the right test: FII for a CFII, AIF only if you already hold a flight instructor certificate, IGI for an instrument ground instructor rating — confirm with your instructor or examiner.
- The testing matrix lists no instructor endorsement for a first attempt at FII, AIF or IGI — check the current matrix before you book.
- Plan for FOI too unless you're exempt: current flight or ground instructors, state-certified teachers for grade 7 or higher and accredited college or university teachers don't take it (61.183(e), 61.213(b)).
- If you retake after a failure, bring the failed test report and an endorsement from an authorized instructor who gave you the additional training.
Exam-day game plan
How to walk in ready — and how to pace 50 questions in 2 hours 30 minutes.
Pacing checkpoints
Our timed test uses the FII length and time — 50 questions in 2 hours 30 minutes — as one block of single-answer, three-choice questions; IGI is the same length and AIF is shorter (20 questions in 1 hour). Figures that the real test shows from the testing supplement or as embedded images are reproduced as described text, tables or simple diagrams — not the official FAA charts.
The week before
- Take one full-length timed practice test 4–7 days out, then shorter sets and rest.
- Drill holding entries, the alternate rules (1-2-3, 600-2 and 800-2, 45 minutes of reserve fuel) and instrument currency and IPC rules until they're automatic.
- Review instrument instructor privileges and endorsements — who may give instrument training, IPCs and knowledge-test recommendations.
- Confirm your PSI appointment, your FTN, your ID and the flight computer and calculator you'll bring.
During the test
- At 3 minutes a question you have time — spend it on approach plates: read the minimums table, aircraft category and notes before answering.
- Sketch holding patterns and DME arcs on scratch paper before choosing an answer.
- Read for the instructor's angle — many questions ask what a student did wrong or what the instructor must endorse.
- Watch for EXCEPT and NOT — they flip what you're looking for.
- Mark hard questions, answer every one and come back if time allows — there's no penalty for guessing.
Keep your head
- A few nerves sharpen focus. If you freeze, take three slow breaths and reread the question.
- With three choices, ruling out one wrong answer leaves you a coin flip at worst.
- You need 35 of 50 — a few dense approach-plate questions won't sink you.
After you test
- You get your Airman Knowledge Test Report at the test center; it shows your score and the codes of any knowledge areas you missed, and you'll show it to your examiner or with your application.
- For FII or AIF, a passing result is valid for 24 calendar months — complete the CFII practical test within that window. IGI has no practical test: you apply for the instrument ground instructor rating with your passing report (and FOI, unless you're exempt).
- Next for a CFII: the practical test under the Flight Instructor Instrument PTS (FAA-S-8081-9E), where you teach instrument procedures and the examiner reviews your missed topics. Once certificated, flight instructors keep their privileges by meeting the recent-experience requirements every 24 calendar months.
