- The IRH written test has 60 questions, a 2.0-hour allowance and a passing score of 70.
- Passing the written test alone does not award the rating; a practical test with an evaluator is required.
- FAA 2025 data: 597 IRH tests, 94.14% pass rate, 84.47% average score.
What "IHR" Actually Means Here
On this site, IHR stands for the Instrument-Helicopter Rating, an FAA rating that lets a helicopter pilot operate under instrument flight rules (IFR). The acronym is a workflow label. The FAA itself refers to the knowledge test as IRH (Instrument Rating Helicopter), and the standards document is titled Instrument Rating - Helicopter. If you search the FAA's own materials, search for "IRH" and "Instrument Rating - Helicopter."
That naming detail matters because several nearby credentials sound similar but are different things. This article is not about the Instrument Rating Airplane test, the Flight Instructor Instrument Helicopter test, the Canadian-conversion test (ICH), or any EASA or other-jurisdiction IR(H) examination. Everything below concerns the FAA rating for helicopter pilots.
If you want the shorter definitional pages first, see What Does IHR Stand For? and IHR Meaning. If you are ready to test your knowledge, the IHR Exam Prep practice test site is the place to start drilling.
The Rating Versus the Written Test
The most common misunderstanding about IHR certification is treating the written test as the credential. It is not. The Instrument-Helicopter Rating is earned in stages:
- Meet the eligibility conditions in 14 CFR 61.65 (certificate, English proficiency, ground preparation, endorsements).
- Pass the IRH computer-based knowledge test.
- Accumulate the required flight experience.
- Pass the practical assessment (ground/oral plus flight) with an authorized FAA evaluator or designated pilot examiner.
One useful exception: under 14 CFR 61.65(a)(7), an applicant who already holds an instrument rating in another aircraft category is exempt from taking another knowledge test. Adding instrument-helicopter privileges to, say, an airplane instrument rating still requires the applicable practical test and the experience requirements, but not a second written test.
The Eight ACS Areas of Operation
The FAA's Instrument Rating - Helicopter Airman Certification Standards (FAA-S-ACS-14) defines what a candidate must know, manage and perform. The cover is dated November 2023, while the FAA's ACS index lists the document as April 2024, effective May 31, 2024. That index date is not a new 2026 edition. The ACS replaced the older Practical Test Standards, so material built on an obsolete helicopter PTS or an airplane ACS should be treated with caution.
The ACS organizes the rating into eight Areas of Operation. These are the official groupings of tasks, not eight weighted sections of the written test; the FAA has not published percentage weights for them, so no area can honestly be called the "biggest."
Domain 1: Preflight Preparation
Covers pilot qualifications, weather information and cross-country flight planning.
- Currency and qualification checks for IFR flight
- Reading and applying weather products to a helicopter IFR plan
- Fuel, alternates and route planning for a helicopter's performance envelope
Domain 2: Preflight Procedures
Aircraft systems related to IFR operations, helicopter flight instruments and navigation equipment, and the instrument flight deck check.
- Which systems and instruments are required or useful for IFR
- Verifying navigation equipment before departure
Domain 3: Air Traffic Control (ATC) Clearances and Procedures
Compliance with ATC clearances and holding procedures.
- Copying, reading back and flying a clearance accurately
- Holding entries and pattern management
Domain 4: Flight by Reference to Instruments
Instrument flight and recovery from unusual flight attitudes.
- Cross-check discipline and attitude control by instruments alone
- Recognizing and recovering from unusual attitudes
Domain 5: Navigation Systems
Intercepting and tracking navigational systems and DME arcs, plus departure, en route and arrival operations.
- Course interception and tracking
- Flying departures, en route segments and arrivals
Domain 6: Instrument Approach Procedures
Non-precision approach, precision approach, missed approach and landing from an instrument approach.
- Approach setup, stabilization and decision points
- Missed approach execution and the transition to landing
Domain 7: Emergency Operations
Loss of communications; instrument approach and landing with a simulated inoperative engine (multiengine helicopter only); and approach with loss of primary flight instrument indicators.
- Lost-communication procedures
- The engine-out task applies only in a multiengine helicopter
- Flying an approach with degraded primary instruments
Domain 8: Postflight Procedures
Checking instruments and equipment after flight.
- Post-flight evaluation of instruments and equipment performance
The subordinate tasks listed under each area do not change the count of eight. For a deeper walk-through, read our complete guide to all 8 IHR content areas.
How the IRH Written Test Works
The current FAA Airman Knowledge Testing Matrix lists the IRH test as follows:
| Item | IRH Written Test |
|---|---|
| Number of questions | 60 |
| Allotted time | 2.0 hours |
| Passing score | 70 |
| Minimum age to take the test | 15 |
| Delivery | Computer-based, at FAA-approved knowledge-testing centers |
| Question style | Objective multiple choice (three choices, per ASA's 2025-2026 test-prep preview) |
The 2.0-hour versus 2.5-hour discrepancy
You may see 2.5 hours quoted in an older ACS appendix. The FAA issued a correction (its ACS Knowledge Test Table, updated October 2024) identifying the older timer as incorrect and setting IRH at 2.0 hours effective January 27, 2025. Publisher ASA independently confirmed the change in a February 2025 update to its instrument test book. The current matrix is the controlling source. One more nuance: the published 60-question count excludes any unscored validation questions, whose number is not disclosed, and the two-hour allowance includes time to answer them.
Authorization, Booking and Test-Day Rules
Before you can sit
- A Federal Tracking Number (FTN) obtained through IACRA.
- Current acceptable identification and address evidence.
- For a first attempt, either a ground-course completion document from an FAA-certificated school or a readiness endorsement from an authorized instructor.
- For a retest after failure, the failed Airman Knowledge Test Report plus an endorsement after additional instruction.
Booking
The FAA's testing page directs candidates to PSI Services and its booking portal. When we checked, the login page was branded Talogy and did not display an authenticated current fee, so no universal booking price can be quoted here. Testing happens at FAA-approved knowledge-testing centers; a home-study course does not mean you can take the test at home.
What you may bring
FAA Order 8080.6H permits specified arithmetic and aviation calculators and navigation aids, under proctor control and with stored information erased. This is not an open-book exam: personal study notes and electronic reference libraries are not allowed.
About "exam questions"
The FAA states that live test questions are not released and points applicants to PSI sample tests. Be skeptical of any site advertising an "official live question bank." Practice questions are for learning concepts, not for recalling secure items. Our practice tests are built that way.
Prerequisites for the Full Rating
14 CFR 61.65 governs the rating. In outline, you need an appropriate private-pilot certificate (or a concurrent application), English proficiency, the applicable ground preparation and endorsements, the prescribed flight experience, and successful completion of the applicable tests. For the ordinary Part 61 helicopter route, the experience includes:
- 50 hours of cross-country flight as pilot in command, including 10 in helicopters.
- 40 hours of actual or simulated instrument time, including 15 hours with an instructor holding instrument-helicopter privileges.
- Three hours of helicopter instrument practical-test preparation within the preceding two calendar months.
- An instructed, IFR-filed cross-country flight of at least 100 nautical miles, with an instrument approach at each airport and three different kinds of approaches using navigation systems.
These are rating-completion requirements, not a rule that every hour must precede the written test. Approved simulator and device credits, combined-training provisions and alternative approved training pathways have their own conditions and should be checked separately. No college degree or personal recommendation letter is required; instructor endorsements are not personal references. For a fuller checklist, see IHR requirements: eligibility and prerequisites.
The Practical Assessment
The practical is separate from the knowledge-testing appointment and is conducted by an authorized FAA evaluator or designated pilot examiner. It has a ground/oral portion and a flight portion, each measured against the applicable ACS knowledge, risk-management and skill standards. Oral questioning continues during the flight. A failed required task can fail the practical.
We did not verify a fixed number of practical questions or a universal time limit, and we will not invent one. What the ACS makes clear is the shape of the evaluation: the eight areas above, including the conditional multiengine engine-out approach (applicable only if you test in a multiengine helicopter) and the approach flown with loss of primary flight instrument indicators.
Key Takeaway
Treat the written test as a knowledge gate and the practical as the real proof. Spend your flight and simulator hours on cross-check discipline, holding, approaches and emergency tasks, the things an evaluator will actually have you fly.
Pass Rates, Costs and Pay: What the Data Supports
Pass rate
The FAA's 2025 Airman Knowledge Test Statistics report Instrument Rating Helicopter volume of 597 tests, a pass rate of 94.14% and an average score of 84.47%. These are 2025 test-administration figures. They are not a first-attempt unique-person rate, a 2026 forecast, a prep-provider success rate or a checkride pass rate; current practical pass-rate statistics were not established. See IHR pass rate: what the data shows for context.
Cost
No universal FAA/PSI public IRH booking price was independently verified. As one provider-published example, a 2026 article from Pelican Flight School quotes USD 175 for the written exam, plus an IR-H program example of USD 16,300 tuition and USD 800-1,200 in examiner fees. Those are one school's examples, not an FAA tariff or a guaranteed all-in price. Preparation products are a separate line item: King Schools advertises USD 299 for a course with 17.4 hours of content, and Sheppard Air lists USD 50 for IRH preparation. Confirm your own booking quote and budget aircraft, instruction and examiner charges separately. Our IHR certification cost breakdown goes line by line.
Pay
The Bureau of Labor Statistics reports May 2025 median annual pay of USD 123,220 for commercial pilots. That is a broad occupational figure, not a helicopter-only or instrument-rating-holder wage, and it is not evidence that this rating alone creates a pay premium. The rating's value is more often about expanded operational capability, such as flying in lower weather minimums and meeting employer requirements for certain flying jobs. For a measured view, read the IHR salary guide and whether the rating is worth it.
Validity, Currency and "Renewal"
Under 14 CFR 61.19, the underlying pilot certificate generally has no stated expiration unless surrendered, suspended or revoked. Do not believe claims that an instrument rating "expires every six months." Three separate clocks are worth distinguishing:
- Knowledge-test eligibility: under 14 CFR 61.39, a passed written test is generally good toward the practical for the preceding 24 calendar months.
- Instrument currency (61.57): to exercise instrument privileges, you need, within the preceding six calendar months, six approaches, holding, and intercepting and tracking navigation courses, under appropriate aircraft or device conditions.
- Lapsed currency: if you remain noncurrent beyond the further six-calendar-month period, an instrument proficiency check is required.
There is no CEU, CDU or CPE renewal tally for this rating in those provisions. Flight reviews and other operating requirements are separate from issuance of the rating.
Sequencing Your Preparation Around the ACS
Because the FAA publishes no domain weights, schedule by dependency rather than by guessed emphasis: weather and planning feed everything, and approaches and emergencies build on core instrument flying. One sample sequence:
Planning, weather and systems
- Domain 1 (qualifications, weather, cross-country planning)
- Domain 2 (IFR systems, instruments, flight deck check)
Clearances and attitude control
- Domain 3 (clearances, holding)
- Domain 4 (instrument flight, unusual attitudes)
Navigation and approaches
- Domain 5 (interception, tracking, DME arcs, departures, arrivals)
- Domain 6 (non-precision, precision, missed approach, landing)
Emergencies and wrap-up
- Domain 7 (lost communications, degraded instruments, multiengine-only task if applicable)
- Domain 8 (postflight checks), then full-length timed practice
For a fuller method, see the IHR study guide, keep the IHR cheat sheet handy for last-minute review, and check IHR exam dates and scheduling to plan your booking.
Frequently Asked Questions
No. The written test is one required step. The full Instrument-Helicopter Rating also requires meeting the 14 CFR 61.65 experience requirements and passing the practical assessment with an authorized FAA evaluator or designated pilot examiner.
The current FAA matrix lists 60 questions, 2.0 hours and a passing score of 70. Unscored validation questions are excluded from the published count, and the two hours includes time for them. An older ACS appendix's 2.5-hour figure was corrected by the FAA.
The underlying pilot certificate generally has no stated expiration, and the rating does not lapse every six months. To exercise instrument privileges you must meet the six-calendar-month currency requirements in 14 CFR 61.57, or complete an instrument proficiency check if you stay noncurrent too long.
No. Under 14 CFR 61.65(a)(7), holding an instrument rating in another aircraft category exempts you from another knowledge test. Adding the helicopter rating still requires the applicable practical test and experience.
No. The FAA does not release live test questions and directs applicants to PSI sample tests. Use practice questions to learn the concepts, and treat any claim of leaked or "official" live questions with suspicion.
