What "IHR" Means on This Page
On this site, IHR means one thing: the Instrument-Helicopter Rating issued under the Federal Aviation Administration's pilot certification rules. "IHR" is our workflow label. The FAA itself calls the knowledge test IRH (Instrument Rating Helicopter) and titles the practical standards Instrument Rating - Helicopter. If you search for either label, you are looking for the same FAA rating.
It is not the Instrument Rating Airplane test, the Flight Instructor Instrument Helicopter test, the Canadian-conversion test (ICH), or an EASA or other non-U.S. IR(H) examination. If you want the background on the name, see What Does IHR Stand For? and What Is IHR?. This cheat sheet condenses what matters most for the FAA rating into a single scan.
Written Test Facts at a Glance
| Item | Must-know fact |
|---|---|
| Test code | IRH (Instrument Rating Helicopter) |
| Questions | 60 (the published count excludes any unscored validation questions, whose number is not disclosed) |
| Time allowed | 2.0 hours, including time to answer unscored items |
| Passing score | 70 |
| Minimum age for the written test | 15 |
| Format | Computer-based, objective multiple choice (publisher materials describe three answer choices) |
| Testing provider | FAA-approved knowledge-testing centers via PSI Services; the booking portal login was branded Talogy |
| Identification | Federal Tracking Number from IACRA plus acceptable ID and address evidence |
Two more logistics points. First, the written test is not open-book. Proctors may permit specified calculators and navigation aids and will require stored information to be erased, but personal notes and electronic reference libraries are not allowed. Second, the FAA does not release live exam questions. It directs applicants to PSI sample tests, so be skeptical of any site that claims to show "actual" secure items. Third-party question banks are practice material, not the real exam. For a plan built around that reality, see our IHR study guide.
The matrix lists a revision date of September 25, 2026 in retrieved text, while the rendered table still carries an October 22, 2025 footer. Both versions give the same IRH figures, so the inconsistency doesn't change what you need to know, but verify the numbers on your booking screen.
The Eight ACS Areas of Operation
The governing standard is the Instrument Rating - Helicopter Airman Certification Standards (FAA-S-ACS-14). The cover is dated November 2023; the FAA's index lists it as April 2024, effective May 31, 2024. That index date is not a new 2026 edition. The ACS replaced the older Instrument Rating Practical Test Standards, so don't study from an obsolete helicopter PTS or an airplane ACS.
The eight Areas of Operation below are the complete official list. They integrate knowledge, risk management and skill. They are not eight weighted sections of the written test, and the FAA has not published percentage weights or per-area item counts. Treat any "Domain 4 is 30% of the test" claim as invented. For a deeper walkthrough, read IHR Exam Domains: Complete Guide to All 8 Content Areas.
Domain 1: Preflight Preparation
Pilot qualifications, weather information and cross-country flight planning.
- Instrument currency and privilege limits
- Interpreting weather products for an IFR flight
- Planning an IFR route with fuel, alternates and performance in mind
Domain 2: Preflight Procedures
Aircraft systems related to IFR operations, helicopter flight instruments and navigation equipment, and the instrument flight deck check.
- Systems that matter for IFR: electrical, pitot-static, vacuum or electronic equivalents
- Gyroscopic and navigation instrument behavior and limitations
- A deliberate flight deck check 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
- Entering and flying holding patterns, including wind correction
Domain 4: Flight by Reference to Instruments
Instrument flight and recovery from unusual flight attitudes.
- Attitude instrument flying and cross-checking
- Recognizing and recovering from unusual attitudes using instruments alone
Domain 5: Navigation Systems
Intercepting and tracking navigational systems and DME arcs, plus departure, en route and arrival operations.
- Intercepting and tracking courses with the equipment installed
- Flying DME arcs
- Departure, en route and arrival procedures
Domain 6: Instrument Approach Procedures
Non-precision approach, precision approach, missed approach and landing from an instrument approach.
- Reading approach plates and identifying minimums
- Stabilized approach technique and go/no-go decisions at the missed approach point
- Transitioning from instruments to a visual landing
Domain 7: Emergency Operations
Loss of communications; instrument approach and landing with a simulated inoperative engine (multiengine helicopter only); approach with loss of primary flight instrument indicators.
- Lost-communications rules and decision-making
- The inoperative-engine task applies only in a multiengine helicopter
- Flying with failed primary indicators using remaining instruments
Domain 8: Postflight Procedures
Checking instruments and equipment.
- Noticing instrument or equipment discrepancies after flight
- Closing the loop on what you observed in the air
The subordinate tasks listed under each area don't change the count: it remains eight Areas of Operation. Notice that Domains 2 and 8 bracket the flight with equipment checks. Candidates who skip them on the theory that "only approaches matter" tend to be surprised by oral questioning.
Eligibility, Endorsements and Booking
Under 14 CFR 61.65, the rating requires an appropriate private-pilot certificate (or concurrent application), English proficiency, applicable ground preparation and instructor endorsements, prescribed flight experience and successful applicable tests. No college degree and no personal recommendation letter are required. Instructor endorsements are an authorization, not a reference. For a fuller eligibility walkthrough, see IHR Requirements: Eligibility, Prerequisites & How to Qualify.
- Get your Federal Tracking Number through IACRA.
- Obtain authorization for the first attempt: either an acceptable FAA-certificated-school ground-course completion document or an authorized instructor's readiness endorsement.
- Book through the FAA's testing channel (PSI Services; the portal login was branded Talogy) and bring acceptable ID and address evidence.
- After a failure, a retest requires the failed Airman Knowledge Test Report and an endorsement after additional instruction.
Scheduling windows and timing questions are covered in IHR Exam Dates: Testing Windows, Deadlines & Scheduling, and the exact score threshold is in IHR Passing Score.
Flight Experience Checklist
These are rating-completion requirements under the ordinary Part 61 helicopter route. They are not a claim that every hour must precede the written test.
- 50 hours of cross-country time as pilot in command, including 10 in helicopters
- 40 hours of actual or simulated instrument time, including 15 with an instructor holding instrument-helicopter privileges
- 3 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
Approved simulator and device credits, combined-training provisions and alternative approved training pathways carry their own conditions, so check them separately with your instructor or school rather than assuming the standard route applies.
Pass Rate, Cost and Pay Numbers
Pass rate
The FAA's 2025 Airman Knowledge Test Statistics report Instrument Rating Helicopter volume of 597, a pass rate of 94.14% and an average score of 84.47%. Read these carefully: they describe 2025 test administrations, not a first-attempt unique-person rate, a 2026 forecast, a prep provider's success rate or the pass rate for the full rating and practical. A current practical pass rate was not established. More on interpreting these figures is in IHR Pass Rate: What the Data Shows and How Hard Is the IHR Exam?.
Cost
No universal public FAA/PSI booking price for IRH was independently verified, so confirm the quote when you book. One helicopter school's published 2026 cost article quotes USD 175 for the written exam, plus an IR-H program example of USD 16,300 tuition and USD 800-1,200 examiner fees. Those are one school's examples, not an FAA tariff or a guaranteed all-in price. Keep these buckets separate:
| Cost bucket | What to remember |
|---|---|
| Written test fee | Confirm the booking quote; the school example above was USD 175 |
| Prep materials | Not an exam fee. Examples seen: a King Schools course at USD 299 (17.4 hours of content) and Sheppard Air IRH prep at USD 50 |
| Aircraft and instruction | Billed separately by your school or instructor |
| Examiner fee | Separate from the knowledge-test appointment; the school example was USD 800-1,200 |
For a fuller breakdown, see IHR Certification Cost: Complete Pricing Breakdown.
Pay
The Bureau of Labor Statistics reports a May 2025 median annual pay of USD 123,220 for commercial pilots. That is a broad occupational figure, not a helicopter-only number and not evidence that this rating alone creates a wage premium. For perspective on earnings and return, see the IHR Salary Guide and Is the IHR Certification Worth It?.
The Practical: What the Written Test Doesn't Cover
Passing the IRH written test alone does not award the rating. The practical is conducted by an authorized FAA evaluator or designated pilot examiner, separately from the knowledge-testing appointment, and it has a ground/oral portion and a flight portion. Both are measured against the applicable ACS knowledge, risk-management and skill standards, and oral questioning continues during the flight. A failed required task can fail the practical.
- No fixed practical question count or universal practical time limit was verified.
- Flight-training hours and prep-course runtimes are not the written-test timer.
- The simulated inoperative-engine approach is a multiengine-only task; in a single-engine helicopter it doesn't apply.
Key Takeaway
Use written-test prep to build knowledge, then deliberately rehearse the flight tasks in the aircraft or approved device. A candidate who can answer questions about holding entries but hasn't flown them to standard is prepared for the written test, not the practical.
Currency, Validity and Renewal
- The certificate itself: under 14 CFR 61.19, the underlying pilot certificate generally has no stated expiration unless surrendered, suspended or revoked. Do not claim the instrument rating expires every six months.
- Written test eligibility: a knowledge test result is standardly good for a practical within the preceding 24 calendar months (14 CFR 61.39).
- Exercising privileges: 14 CFR 61.57 requires instrument experience in the preceding six calendar months: six approaches, holding, and intercepting and tracking navigation courses, with appropriate aircraft or device conditions.
- Lapsed currency: if you stay noncurrent beyond the further six-calendar-month period, an instrument proficiency check is required.
- Renewal credits: there is no CEU/CDU/CPE tally for this rating in these provisions. Proficiency, flight-review and other operating requirements are separate from rating issuance.
The key distinction: the rating doesn't lapse, but your privilege to fly in instrument conditions depends on staying current. Candidates sometimes confuse test-report validity with currency; they are different clocks.
A Domain-Ordered Review Plan
Because the FAA publishes no weights, there is no basis for declaring one domain "most heavily tested." Sequence your review by dependency instead: planning and equipment knowledge first, procedures second, emergencies last. This plan is a suggestion, and the order is what matters, not the calendar.
Domains 1 and 2: Planning and Equipment
- Weather products, IFR flight planning and currency rules
- Instruments, navigation equipment and the flight deck check
Domains 3 and 4: Clearances and Instrument Flight
- Clearance copying and holding entries
- Attitude instrument flying and unusual-attitude recovery concepts
Domains 5 and 6: Navigation and Approaches
- Course interception, tracking and DME arcs
- Plate reading, minimums and missed approach logic
Domains 7 and 8, then full review
- Lost communications, failed-indicator approaches and the multiengine-only task
- Postflight equipment checks, then timed practice sets at the 2.0-hour limit
Practice sets are most useful for building pace and spotting weak topics. Try the IHR practice test for timed drills, and revisit the main practice site after each week to see which domains still need work. Cross-check any question explanations against the ACS rather than trusting a third-party answer key, and avoid using airplane-only questions indiscriminately, since helicopter-specific considerations differ.
Frequently Asked Questions
The FAA testing matrix lists 60 questions and 2.0 hours, with a passing score of 70. The published count excludes unscored validation questions, and the time allowance includes time to answer them. An older ACS appendix still shows 2.5 hours, but the FAA's correction table and current matrix supersede it.
No. You must also meet the flight experience and endorsement requirements of 14 CFR 61.65 and pass the practical with an authorized evaluator or designated pilot examiner. The written test is one required step, valid for a practical within 24 calendar months under the standard rule.
The FAA has not published percentage weights or item counts for them. The eight Areas of Operation describe what the ACS expects across knowledge, risk management and skill. Be wary of any resource claiming specific percentages per domain.
No. The pilot certificate generally has no stated expiration unless surrendered, suspended or revoked. What recurs is currency: 14 CFR 61.57 requires recent approaches, holding and course tracking to exercise instrument privileges, and a long lapse calls for an instrument proficiency check.
Under 14 CFR 61.65(a)(7), an applicant who already holds an instrument rating in another aircraft category is exempt from another knowledge test. You still need the applicable helicopter flight experience and must pass the practical.
