- The initial helicopter instructor knowledge test is code FRH: 100 scored questions, 150 minutes, 70% to pass.
- FAA's 2025 FRH pass rate was 98.27% across 520 administrations, which is not a first-attempt or practical-test figure.
- The ACS (FAA-S-ACS-29, effective May 31, 2024) has 13 unweighted Areas of Operation, not weighted exam domains.
- Certificates issued from December 1, 2024 do not expire, but instructing privileges still depend on recent experience under 14 CFR 61.197.
What This Cheat Sheet Covers
This page condenses what a candidate needs to recall quickly about the Flight Instructor Certificate with Rotorcraft Category and Helicopter Rating, the credential most pilots shorten to CFI-H. It is an FAA certificate, issued under 14 CFR Part 61, and it authorizes you to give flight and ground instruction in helicopters. It is not a private-sector credential, and nothing here applies to similarly abbreviated certifications from other bodies.
If you are brand new to the topic, start with What Is CFI-H? or What Does CFI-H Stand For? for the vocabulary. If you want a full preparation roadmap rather than a quick reference, the CFI-H Study Guide 2026 goes deeper. This article is the one-page recall layer: print it, tape it up, and test yourself against it.
One naming quirk is worth memorizing immediately. "CFI-H" is shorthand, not an official FAA test code. The initial helicopter instructor knowledge test is coded FRH, and that is the code you will see when you register. The test code is not FIH, even though some forums and study sites use that spelling.
The Numbers That Matter: Format, Fees, Score
Most of the exam-day facts fit in one table. Memorize these so nothing about the logistics surprises you in the testing center.
| Item | FRH (Initial Helicopter Instructor) | FOI (Fundamentals of Instructing) | HFA (Add-On) |
|---|---|---|---|
| Scored questions | 100 multiple choice | 50 | 25 |
| Time allowed | 150 minutes | 90 minutes | 60 minutes |
| Passing score | 70% | 70% | 70% |
| Delivery | PSI testing center | PSI testing center | PSI testing center |
Two additional details trip people up. First, the FRH may include unscored validation items mixed in with the 100 scored questions, so a test that feels longer than 100 items is not a sign something went wrong. Second, you cannot tell which questions are unscored, so treat every item as real.
Fee mechanics
One current testing center lists $175 per knowledge test. Treat that as a reference point and confirm the booking price when you schedule, because centers set their own fees. The FOI test adds another fee when it is required, and practical-test and flight-training costs are entirely separate line items. For a realistic total, see the CFI-H Certification Cost breakdown.
Passing score in plain terms
On a 100-question scored test, 70% means you need 70 correct. Because validation items are unscored, do not try to back-calculate your result from how many questions you saw. For scoring details, read CFI-H Passing Score: Exactly What You Need to Pass.
Eligibility and Certificate Facts at a Glance
Before you can be issued the certificate, several boxes must be checked. This is the compact version; the CFI-H Requirements guide covers each one in detail.
- Age: at least 18.
- Language: able to read, speak, write, and understand English.
- Pilot certificate: a suitable commercial or ATP certificate with the appropriate rotorcraft-helicopter rating.
- Experience: 15 hours of pilot-in-command time in the category and class (rotorcraft-helicopter).
- Training and endorsements: the required ground and flight instruction and logbook endorsements.
- Knowledge tests: the applicable FRH and FOI tests, with specified FOI exemptions for certain applicants.
- Practical test: a practical evaluation conducted against the Airman Certification Standards.
The 13 ACS Areas of Operation
The practical test is built from the Airman Certification Standards, document FAA-S-ACS-29, effective May 31, 2024. It lists 13 Areas of Operation. These are not weighted, and there is no "largest domain" on the knowledge test that you can prioritize by percentage. Any Area can generate questions or evaluation points, so the safest approach is balanced coverage. For a deeper walk through each area, see the CFI-H Exam Domains Guide.
| # | Area of Operation | What it tests |
|---|---|---|
| 1 | Fundamentals of Instructing | Learning theory, teaching methods, evaluation, risk management in training |
| 2 | Technical Subject Areas | Aeromechanics, systems, weather, regulations, performance data |
| 3 | Preflight Preparation | Planning, weight and balance, airworthiness, pilot qualifications |
| 4 | Preflight Lesson on a Maneuver to be Performed in Flight | Delivering a structured ground lesson on a maneuver |
| 5 | Preflight Procedures | Preflight inspection, cockpit management, starting, run-up |
| 6 | Airport and Heliport Operations | Communications, markings, lighting, traffic patterns |
| 7 | Hovering Maneuvers | Vertical takeoff and landing, hovering, hover taxi, pivots |
| 8 | Takeoffs, Landings, and Go-Arounds | Normal, crosswind, steep approach, slope, confined area techniques |
| 9 | Fundamentals of Flight | Basic flight maneuvers and control technique |
| 10 | Performance Maneuvers | Rapid decelerations, ground reference maneuvers |
| 11 | Emergency Operations | Autorotations, system malfunctions, settling with power response |
| 12 | Special Operations | Specialized helicopter operations and environments |
| 13 | Postflight Procedures | Parking, securing, postflight inspection and documentation |
Key Takeaway
Two Areas, Fundamentals of Instructing and Preflight Lesson on a Maneuver to be Performed in Flight, test you as a teacher, not as a pilot. Candidates who have strong stick-and-rudder skills but have never organized a lesson plan often lose points here. Practice delivering these lessons out loud.
Knowledge-Test Topics You Must Own
The FRH draws on the helicopter-specific knowledge an instructor must teach, so recall speed on the core subjects matters. Below are the clusters worth drilling, grouped to match the ACS Areas.
Technical Subject Areas
This is the densest content area. Expect to move between theory and application.
- Aerodynamics: dissymmetry of lift, blade flapping, coning, translational lift, ground effect in and out of ground effect
- Retreating blade stall and compressibility, and the conditions that produce them
- Vortex ring state (settling with power): causes, indications, and recovery technique
- Dynamic rollover: critical conditions and prevention
- Mast bumping and low-G hazards in semirigid rotor systems
- Weight and balance, density altitude effects, and performance charts including hover ceiling
- Powerplant, transmission, rotor system, and flight control fundamentals
Emergency Operations
Know the sequence and the reasoning, since you will be expected to teach both.
- Autorotation entry, glide, flare, and touchdown, including the factors that change rotor RPM and glide distance
- Height-velocity diagram: what the avoid area means and why it exists
- Antitorque system failures and the different responses for loss of thrust versus fixed-pitch conditions
- Engine failures at hover versus in cruise, and how the response differs
Airport and Heliport Operations and Special Operations
These areas reward candidates who have flown beyond the standard training syllabus.
- Heliport markings, lighting, and wind indicators
- Traffic patterns and communications specific to rotorcraft
- Confined area, pinnacle, and ridgeline operations, including recon and go/no-go decision-making
- Slope operations: limits, technique, and common errors
Common Traps in Fundamentals of Instructing
Whether you take the standalone FOI test or face FOI content during the practical, the same concepts recur. Learn them as definitions you can apply to scenarios.
- Levels of learning: rote, understanding, application, correlation. Questions often ask you to identify the level a lesson objective targets.
- Learning domains and theories: know the basics of behaviorism and cognitive approaches and how they shape lesson design.
- Student evaluation: the difference between oral quizzes, written tests, and performance evaluation, and what makes a test reliable and valid.
- Critique methods: constructive critique should be specific and tied to objectives; avoid vague approval or blame.
- Lesson planning: objective, content, schedule, equipment, and completion standards.
- Human behavior: defense mechanisms, anxiety, and attention, especially as they affect a nervous student in a helicopter.
Helicopter Technical Traps
The most common point losses come from confusing two similar-sounding phenomena or from reversing a cause-and-effect relationship. Keep these contrasts in your head.
| Concept Pair | Distinguish By |
|---|---|
| Settling with power vs. retreating blade stall | Settling with power arises from descent through your own downwash at low airspeed with power applied; retreating blade stall arises from high forward speed, high load, and high blade angle |
| Dynamic rollover vs. ground resonance | Dynamic rollover involves a pivot point on the ground and lateral roll; ground resonance is a vibration coupling between rotor and landing gear |
| Translational lift vs. ground effect | Translational lift comes from forward airspeed improving rotor efficiency; ground effect comes from proximity to the surface altering rotor airflow |
| Dissymmetry of lift vs. flapping | Dissymmetry is the unequal lift between advancing and retreating halves; flapping is how the blades respond to equalize it |
For a sense of where candidates find the knowledge test harder than expected, the How Hard Is the CFI-H Exam? article discusses difficulty drivers without inflating or deflating the picture.
Privileges, Recency, and Renewal
Recent changes mean older advice about two-year expiration no longer applies cleanly.
- Flight instructor certificates issued from December 1, 2024 do not expire.
- Exercising instructor privileges still requires recent experience within the preceding 24 calendar months under 14 CFR 61.197.
- There is no universal continuing-education quota you can cite as a blanket rule; the recent experience provisions in the regulation govern.
Key Takeaway
"Non-expiring" does not mean "always current." A certificate in your wallet and the legal ability to instruct are two different things. Track your 24-calendar-month recency window in your logbook and consult the current text of 14 CFR 61.197 for the qualifying methods.
A Domain-Ordered Review Plan
Because the Areas are unweighted, the plan below is ordered by dependency, not by percentage. Technical foundations come first because later maneuver and emergency topics build on them. Adjust the pace to your own timeline and the dates in the CFI-H exam dates guide.
Technical Subject Areas
- Aerodynamics of rotors, dissymmetry, flapping, translational lift
- Systems and weight and balance practice problems
Fundamentals of Instructing and Lesson Delivery
- Levels of learning, evaluation, critique methods
- Practice the Preflight Lesson area by teaching one maneuver aloud
Maneuver Areas: Hovering, Takeoffs/Landings, Fundamentals of Flight, Performance Maneuvers
- Common errors, corrections, and teaching sequences
- Airport and heliport operations and preflight procedures
Emergency, Special, and Postflight Operations
- Autorotation reasoning, height-velocity diagram, vortex ring recovery
- Full timed practice tests, then targeted review of misses
Finish with timed question practice. The CFI-H practice tests mirror the multiple-choice style of the FRH so you can build pacing for the 150-minute window.
Who Hires Helicopter Instructors
Holding the certificate opens doors across several kinds of operators. Typical employers include helicopter flight schools and training academies, university aviation programs with rotorcraft tracks, and operators that run in-house training for tour, utility, medical, or offshore flying. Many instructors also use the job as a time-building stage toward commercial helicopter work. For role-by-role detail, see CFI-H Jobs, and for the financial angle, the CFI-H Salary Guide and ROI analysis weigh cost against career upside qualitatively. Pay varies widely by region, employer, and flying volume, so treat any single number you see online with caution.
Frequently Asked Questions
The code is FRH. CFI-H is common shorthand for the certificate, but FRH is the code you will use when registering for the initial helicopter instructor knowledge test with a PSI testing center.
The FRH has 100 scored multiple-choice questions, possibly alongside unscored validation items, with 150 minutes allowed. You need 70% to pass.
Not necessarily. That FAA 2025 figure covers 520 administrations of the FRH and is not a first-attempt rate or a practical-test result. It shows most sittings end in a pass, which usually reflects candidates testing after structured preparation.
Generally yes, unless you qualify for a specified exemption under the regulation. The FOI is 50 questions in 90 minutes with a 70% passing score, and it carries its own fee. Confirm your exemption status before skipping it.
Certificates issued from December 1, 2024 do not expire. However, you must meet the 24-calendar-month recent experience requirements of 14 CFR 61.197 to exercise instructor privileges, so keep your logbook current.
For a broader introduction to the credential and how the pieces fit together, revisit CFI-H Certification, and when you are ready to pressure-test your recall, run a timed session on the main practice test site.
