- IHR here means Instrument-Helicopter Rating, an FAA rating; the FAA's written test code is IRH.
- The IRH written test has 60 questions, a 2.0-hour allowance and a passing score of 70.
- The FAA's 2025 statistics show IRH volume of 597 and a 94.14% pass rate.
- Passing the written test alone does not award the rating; a practical assessment is required.
What IHR Means Here
On this site, IHR means Instrument-Helicopter Rating: the Federal Aviation Administration rating that lets a pilot fly a helicopter under instrument flight rules (IFR) by reference to instruments, in weather where outside visual references are not reliable. The acronym is shared by several unrelated credentials in other fields, and none of those are covered here. If you arrived looking for another "IHR," this article will not help you; if you are a helicopter pilot weighing an instrument rating, you are in the right place.
For a quick orientation, the short-form explainers What Is IHR? and What Does IHR Stand For? cover the same ground in less depth. This article goes further: it explains how the label maps onto official FAA terminology, what the written test and practical actually involve, and what a candidate must master.
IHR, IRH and the Nearby Tests
"IHR" is the workflow label used on this site. The FAA itself uses different names, and knowing them prevents booking the wrong test or studying the wrong standards.
| Name | What it is |
|---|---|
| IHR (this site's label) | Instrument-Helicopter Rating, the FAA rating |
| IRH | The FAA knowledge-test code: Instrument Rating Helicopter |
| Instrument Rating - Helicopter ACS (FAA-S-ACS-14) | The Airman Certification Standards that govern the practical |
| Instrument Rating Airplane test | A different FAA test; not the helicopter rating |
| Flight Instructor Instrument Helicopter test | An instructor-level test, not the rating itself |
| ICH | A Canadian-conversion test; separate from IRH |
| EASA IR(H) | A European-jurisdiction examination, outside FAA scope |
When you search for practice material, use FAA and IRH qualifiers. Airplane-oriented questions can mislead a helicopter candidate, because helicopter instrument flying differs in aircraft systems, flight instruments, approach technique and emergency procedures. The main practice test site keeps its material focused on the helicopter rating.
The Written Test at a Glance
The knowledge test is computer-based and delivered through FAA-approved knowledge-testing centers. Booking runs through the FAA's designated provider, PSI Services, whose portal appeared under Talogy branding when checked. A home-study course is not at-home proctored testing; you still sit the exam at a testing center.
| Item | IRH written test |
|---|---|
| Questions | 60 (published count excludes any unscored validation questions) |
| Time allowed | 2.0 hours |
| Passing score | 70 |
| Minimum age for the written test | 15 |
| Format | Objective multiple choice, three choices per question (per publisher preview material) |
| 2025 volume and pass rate | 597 tests; 94.14% pass rate; 84.47% average score |
The 94.14% figure comes from the FAA's 2025 Airman Knowledge Test Statistics. It describes test administrations, not unique first-attempt candidates, and it says nothing about checkride outcomes. For interpretation, see IHR Pass Rate 2026: What the Data Shows and IHR Passing Score 2026: Exactly What You Need to Pass. For realistic expectations about difficulty, read How Hard Is the IHR Exam?
Test-day mechanics
- Federal Tracking Number: obtain one through IACRA before booking.
- Identification: bring current acceptable identification and address evidence.
- First-attempt authorization: an acceptable ground-course completion document from an FAA-certificated school, or an authorized instructor's readiness endorsement.
- Retest after a failure: the failed Airman Knowledge Test Report plus an endorsement after additional instruction.
- Aids: specified calculators and navigation aids may be allowed under proctor control with stored information erased; this is not an open-book exam, and personal notes or electronic libraries are not permitted.
- Question security: live questions are not released, and the FAA directs applicants to PSI sample tests. Be skeptical of any site claiming to offer the actual exam items.

The Eight ACS Areas of Operation
The Instrument Rating - Helicopter ACS (FAA-S-ACS-14) replaced the older Practical Test Standards. It lists eight Areas of Operation that integrate knowledge, risk management and skill. These are the official areas of the practical standards, not eight weighted sections of the written test, and the FAA has not published percentage weights for them. Anyone claiming a "highest-weighted domain" is guessing. A fuller walkthrough is in IHR Exam Domains 2026: Complete Guide to All 8 Content Areas.
Domain 1: Preflight Preparation
Tasks: Pilot Qualifications; Weather Information; Cross-Country Flight Planning.
- Be ready to explain what you are legally and personally qualified to do, including instrument currency.
- Interpret weather products for IFR decisions: icing, convective activity, ceilings and visibility, and alternates.
- Plan an IFR cross-country with fuel, performance and alternate considerations specific to helicopters.
Domain 2: Preflight Procedures
Tasks: Aircraft Systems Related to IFR Operations; Helicopter Flight Instruments and Navigation Equipment; Instrument Flight Deck Check.
- Know which systems and instruments are required for IFR and how failures affect the flight.
- Understand how gyroscopic, pitot-static and navigation instruments work and fail.
- Perform and explain a flight deck check appropriate to instrument flight.
Domain 3: Air Traffic Control (ATC) Clearances and Procedures
Tasks: Compliance with ATC Clearances; Holding Procedures.
- Copy, read back and fly clearances accurately, and recognize when to query or amend.
- Enter and fly holds, including entry selection and wind correction.
Domain 4: Flight by Reference to Instruments
Tasks: Instrument Flight; Recovery from Unusual Flight Attitudes.
- Maintain control with an instrument scan, which in a helicopter means managing an inherently less stable aircraft.
- Recover from unusual attitudes smoothly and in the correct order.
Domain 5: Navigation Systems
Tasks: Intercepting and Tracking Navigational Systems and DME Arcs; Departure, En Route, and Arrival Operations.
- Intercept and track courses using the navigation equipment in your aircraft.
- Fly DME arcs and handle departures, en route segments and arrivals under IFR.
Domain 6: Instrument Approach Procedures
Tasks: Non-precision Approach; Precision Approach; Missed Approach; Landing from an Instrument Approach.
- Fly both approach categories to published minimums with stabilized technique.
- Execute a missed approach correctly and transition to a landing when visual references allow.
Domain 7: Emergency Operations
Tasks: Loss of Communications; Instrument Approach and Landing with an Inoperative Engine (Simulated) (Multiengine Helicopter Only); Approach with Loss of Primary Flight Instrument Indicators.
- Know the lost-communications procedures and the reasoning behind them.
- The inoperative-engine task applies only if you test in a multiengine helicopter.
- Practice partial-panel flying, since loss of primary indicators is a core emergency skill.
Domain 8: Postflight Procedures
Task: Checking Instruments and Equipment.
- Verify after the flight that instruments and equipment performed correctly, and know how to document and act on discrepancies.
The eight-area count does not change when subordinate tasks are listed under each header. A one-page recap is in IHR Cheat Sheet 2026.
Written Test Versus Practical
The two assessments are separate events, and a good score on one does not predict the other.
- Written (IRH) test: a 60-question knowledge test at a testing center. Passing it satisfies the knowledge requirement but does not award the rating.
- Practical assessment: conducted by an authorized FAA evaluator or designated pilot examiner, separately from the knowledge-testing appointment. It has a ground/oral portion and a flight evaluation measured against the ACS knowledge, risk-management and skill standards. Oral questioning continues during the flight, and failing a required task can fail the practical.
No fixed practical question count or universal practical time limit was verified, so treat anyone quoting one with caution. Written preparation builds the knowledge side; proficiency on the practical comes from flight training. Don't treat flight-training hours or a prep-course runtime as a timer for either.
What the Rating Requires
Current 14 CFR 61.65 requires an appropriate private-pilot certificate or concurrent application, English proficiency, applicable ground preparation and instructor endorsements, prescribed flight experience, and successful tests. For the ordinary Part 61 helicopter route, the experience includes:
- 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.
- 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 statement that every hour must precede the written test. Approved simulator and device credits, combined-training provisions and alternative approved pathways each carry their own conditions, so verify them with your instructor or school. The sources cited here state no college degree and no personal recommendation letters; instructor endorsements are not personal references. For a plain-language breakdown, see IHR Requirements 2026: Eligibility, Prerequisites & How to Qualify.
Currency, Validity and Renewal
Candidates often confuse several different clocks.
- The underlying pilot certificate generally has no stated expiration unless surrendered, suspended or revoked (14 CFR 61.19). The instrument rating does not expire every six months.
- Written-test eligibility for a practical is generally within the preceding 24 calendar months (14 CFR 61.39).
- Exercising instrument privileges requires recent experience under 14 CFR 61.57: in the preceding six calendar months, six approaches, holding, and intercepting and tracking navigation courses, with appropriate aircraft or device conditions.
- Falling out of currency beyond the further six-calendar-month period requires an instrument proficiency check.
There is no CEU, CDU or CPE renewal tally for this rating in these provisions. Proficiency, flight-review and other operating requirements are separate from rating issuance.
Key Takeaway
Holding the rating and being current to use it are different things. Track your six approaches, holds and course-tracking events by calendar month, and schedule an instrument proficiency check before your window lapses.
Costs, Careers and Pay Context
No universally applicable public FAA or PSI booking price for the IRH test was independently verified, and the PSI portal did not show an authenticated current fee quote. Confirm the fee when you book. Several different cost categories get blended together, so keep them apart:
| Cost category | What the sources show |
|---|---|
| Written test fee | One 2026 flight-school article quotes USD 175; that is one school's published example, not an FAA tariff |
| Training program | The same school's IR-H example lists USD 16,300 tuition |
| Examiner fees | That example lists USD 800-1,200 |
| Exam preparation products | Prices vary: one retrieved provider page advertised USD 299 for a course with 17.4 hours of content, another listed USD 50 for IRH preparation |
Prep-course prices are not exam fees, and the school example is not a guaranteed all-in price. Aircraft rental, instruction and examiner charges are separate line items. For a fuller breakdown, see IHR Certification Cost 2026: Complete Pricing Breakdown.
Who benefits and what it pays
An instrument rating expands the conditions in which a helicopter pilot can operate safely and legally, which matters for operators who fly in marginal weather and for pilots pursuing more demanding commercial work. On pay, the only figure in our sources is broad: the Bureau of Labor Statistics reports a May 2025 median annual pay of USD 123,220 for commercial pilots. That is not a helicopter-only number and not evidence that this rating alone creates a wage premium, so do not read it as a promise. For the careful version of the argument, see IHR Salary Guide 2026 and Is the IHR Certification Worth It?, and for roles that use the rating, IHR Jobs.
Sequencing Your Preparation
The best study order follows the logic of the flight rather than the order of a textbook. Because the ACS areas are not weighted, give time according to your own weak spots, but this sequence builds knowledge in a sensible order. Use the question practice on the IHR practice test site alongside it, and see the IHR Study Guide 2026 for a broader plan.
Preflight foundations (Domains 1 and 2)
- Weather products, IFR alternates and fuel planning.
- Instrument and systems knowledge, including failure modes.
Clearances and navigation (Domains 3 and 5)
- Clearance copying, holding entries and navigation interception and tracking.
- DME arcs and departure, en route and arrival procedures.
Approaches and instrument flight (Domains 4 and 6)
- Approach chart reading, minimums and missed approaches.
- Scan technique and unusual attitude recovery concepts.
Emergencies, postflight and review (Domains 7 and 8)
- Lost communications and loss of primary instrument indicators.
- Postflight equipment checks, then timed practice under the 2.0-hour limit.
Schedule emergencies after approaches because partial-panel and lost-communications scenarios assume you can already fly a normal approach. Avoid memorizing answers from third-party lists presented as real exam items; the FAA does not release live questions, and understanding the reasoning is what transfers to the practical.
If you came here searching variations like What Does IHR Mean? or What Is IHR Certification?, the answer is the same: a helicopter-specific FAA instrument rating, built on a written test and a practical assessment. For the credential overview, see IHR Certification and IHR Training.
Frequently Asked Questions
IHR stands for Instrument-Helicopter Rating, the FAA rating that allows a helicopter pilot to fly under instrument flight rules. The FAA's own written-test code is IRH, and its standards are titled Instrument Rating - Helicopter.
The FAA testing matrix lists 60 questions, 2.0 hours and a passing score of 70. Older materials citing 2.5 hours were corrected by the FAA effective January 27, 2025.
No. The written test satisfies the knowledge requirement only. You must also complete the required training and experience and pass a practical assessment with an authorized FAA evaluator or designated pilot examiner.
Under 14 CFR 61.65(a)(7), an applicant who holds an instrument rating in another aircraft category is exempt from another knowledge test. You still need the applicable helicopter practical and experience.
The underlying pilot certificate generally has no stated expiration, so the rating does not lapse on a fixed schedule. To use instrument privileges you must meet the recent-experience requirements, and prolonged lapses require an instrument proficiency check.
