Instrument Rating Written Test: What to Know Before You Take the Exam
Preparing for your first IFR exam can feel like a major step because it marks the point where your ground knowledge starts being tested at a higher level. The instrument rating written test covers the rules, weather, navigation, procedures, and decision-making you will rely on as instrument flying becomes more demanding. Knowing what to expect beforehand can make your preparation much more focused.
At Leopard Aviation, we help students connect their ground study with the skills they are developing in the cockpit. Strong preparation is not just аbout passing an exam; it gives you a better foundation for IFR training, checkride preparation, and real-world decisions. Keep reading to see what the test covers, how to prepare effectively, and what you should have in place before exam day.
What the Instrument Rating Written Test Is
The Instrument Rating written test is the FAA knowledge exam you complete as part of earning your Instrument-Airplane rating. Before you start studying intensively, it helps to know exactly what you are preparing for: which exam you need, how it is administered, how much time you receive, and what passing actually accomplishes.
“Written Test” Is the Common Name for a Computer-Based Knowledge Test
Pilots commonly call it the “written test,” although you will not be sitting down with a pencil and a stack of paper. The FAA formally treats it as an Airman Knowledge Test, administered electronically through an authorized FAA knowledge testing center.
For an airplane Instrument Rating, the test code is IRA, short for Instrument Rating Airplane. Knowing that code matters when you schedule because the FAA offers several different instrument-related exams. Make sure you are registering for the test that matches the rating you are pursuing.
The IRA Test Has 60 Scored Questions
According to the FAA’s current Airman Knowledge Testing Matrix, the IRA exam has:
- 60 scored questions
- Two hours of allotted testing time
- A minimum passing score of 70%
The FAA may also include validation questions. These are not scored and do not help or hurt your final result. Importantly, the published 60-question figure does not include validation questions, while the allotted testing time does include the time required to answer them.
That distinction is worth knowing before exam day. If you see more questions than expected, it does not mean somebody at the testing center has invented a bonus round for your personal enrichment.
The Test Covers Knowledge Needed for Real IFR Operations
The exam is designed to test whether you understand the knowledge behind instrument flying, including IFR regulations, air trаffic procedures, navigation, weather, charts, safe aircraft operation, decision-making, and resource management. The FAA’s Instrument Rating ACS ties the knowledge test directly to the areas you will later need to apply during flight training and the practical test.
That means preparation should go beyond memorizing individual answers. You may need to interpret several pieces of information in the same problem and decide what they mean for the flight. When preparing for the FAA written exam, focus on understanding why an answer is correct and how you would use the same information in the cockpit.
Passing the Test Completes One Part of the Rating
A passing score is an important milestone, but it does not complete your Instrument Rating. You still need the applicable aeronautical experience, instrument instruction, instructor endorsements, and practical test required for certification.
You also keep studying after the knowledge exam. Your results help identify areas that deserve additional review, and the practical test includes an oral evaluation where you need to apply your knowledge rather than simply recognize a correct multiple-choice answer.
Think of passing the IRA as clearing one major checkpoint. The bigger goal is to turn that knowledge into sound decisions and reliable IFR flying by the time you reach the checkride.
What You Need Before You Can Schedule the Exam
Before you book the IRA exam, you need to complete a few preparation and registration steps. Fortunately, you do not need every Instrument Rаting flight hour finished first. Your path runs from ground preparation and test authorization to obtaining an FAA Tracking Number and scheduling through the FAA’s contracted testing provider.
Complete the Required Ground Training or Home Study
Under § 61.65, you must receive and log appropriate ground training from an authorized instructor or complete a home-study course covering the required Instrument Rating knowledge areas. Those subjects include IFR regulations, ATC procedures, navigation, charts, weather, decision-making, and safe instrument operations.
You do not need to complete the full set of Instrument Rating requirements before taking the knowledge test. Your required flight experience and instrument proficiency can continue developing after you pass the exam.
Obtain the Required Test Authorization
Before taking the IRA test, you need an acceptable form of authorization. The FAA’s current testing matrix allows qualifying documentation from an FAA-certificated pilot school or a written statement or logbook endorsement from an authorized ground or flight instructor certifying that you are prepared for the exam.
If you are training under Part 61, the usual path is straightforward: complete your knowledge preparation, demonstrate readiness, and receive the required instructor endorsement. Your instructor should make sure you are prepared to apply the material rather than simply recognize memorized answers.
Create an IACRA Account and Obtain an FTN
Before registering for an FAA Airman Knowledge Test, you need an FAA Tracking Number, usually called an FTN. You obtain it by creating an applicant profile through the FAA’s Integrated Airman Certification and Rating Application system, or IACRA.
Your FTN becomes your unique identifier in the FAA testing and certification process. Once you have it, you can create or access your PSI testing account and move into scheduling.
Make Sure Your Personal Information Matches
Check your information carefully before booking. Your name and identifying details in the testing system need to align with your IACRA record аnd the identification you present at the testing center. The FAA notes that PSI receives the applicant’s FTN and name from IACRA and does not let applicants simply edit their name within the PSI system.
If you spot a spelling or name discrepancy, fix it through IACRA before test day. That is considerably easier than discovering that one missing middle name has suddenly become aviation’s most important operational hazard.
Schedule Through the FAA’s Testing Provider
FAA Airman Knowledge Tests are scheduled through PSI, the FAA’s contracted testing vendor. Once your FTN is established and your PSI account is ready, you can select the IRA exam, choose an authorized testing center, pick an available appointment, and complete payment.
Before confirming the appointment, review PSI’s current policies for the exam fee, rescheduling or cancellation, arrival time, permitted calculators or testing aids, identification, and test-center procedures. These operational details can change, so checking them directly before test day gives you one less administrative surprise to deal with when you would rather be thinking about IFR weather and approaches.
What the Instrument Rating Written Test Covers
The IRA exam covers the knowledge you need to plan, understand, and make decisions during IFR operations. You will study regulations, ATC, weather, charts, navigation, approaches, aircraft systems, and risk management. The important part is learning how these subjects connect, because many questions ask you to apply information rather than simply recall a definition.
IFR Regulations and Pilot Responsibilities
You need to know how IFR regulations affect the flight you are planning. That includes pilot qualifications and currency, required aircraft equipment and inspections, fuel and alternate requirements, minimum altitudes, required reports, approach rules, and when an Instrument Rating is required. Focus on what each rule means for your decision as pilot, not simply the wording of the regulation.
The Air Traffic Control System and IFR Clearances
You should be comfortable interpreting what ATC has authorized you to do and recognizing what remains your responsibility. Expect to work with cleаrance limits, routes, assigned altitudes, departure instructions, radar vectors, frequency changes, holds, approach clearances, route amendments, required reports, missed approaches, and lost-communications procedures. The goal is to understand the clearance as an operational instruction, not a collection of radio phrases.
IFR Charts and Published Procedures
Charts can contain a remarkable amount of information in a very small space, because apparently aviation decided white space was a luxury. You need to work confidently with en route charts, approach procedures, airport diagrams, departures, arrivals, and legends while identifying courses, fixes, altitudes, frequencies, minimums, notes, approach segments, missed-approach instructions, and relevant airport information.
Navigation Systems and Flight Planning
You will also need to understand how GPS, RNAV, VOR, and other navigation concepts fit into IFR planning and operation. That includes route selection, airway structure, course interception, waypoint sequencing, navigation databases, equipment limitations, alternate planning, and fuel calculations. You should also be ready to determine what changes when a navigation system becomes unreliable or unavailable during the flight.
Instrument Approaches, Holds, and Missed Approaches
Approach knowledge goes beyond recognizing an approach type. You need to interpret minimum altitudes, decision altitude, minimum descent altitude, approach categories, required visual references, holding instructions, entries, timing, wind correction, and missed-approach procedures. The written exam focuses on whether you understand how the procedure works and when to apply it. The physical execution develops during instrument flight training.
Aviation Weather for IFR Flying
Weather is a major part of IFR decision-making. You should be able to interpret reports, forecasts, ceilings, visibility, winds, fronts, clouds, precipitation, turbulence, wind shear, thunderstorms, icing, freezing levels, pilot reports, graphical products, and developing trends. More importantly, you need to combine that information and decide whether to depart, select an alternate, change your route, continue, divert, or postpone.
Aircraft Instruments, Systems, and Equipment Failures
The test also expects you to understаnd the systems producing the information in front of you. You may work with pitot-static and attitude-heading instruments, electrical systems, glass displays, navigation and communication equipment, autopilots, backup instruments, and required inspections. When something fails, you need to recognize the indications, determine which information remains trustworthy, and understand how the failure affects your plan.
Aeronautical Decision-Making and Resource Management
Finally, IFR knowledge comes together through judgment. You need to think about personal minimums, fatigue, workload, automation, external pressure, fuel reserves, weather risk, equipment capability, and alternate options. You should also know how to use ATC, onboard systems, checklists, and other resources effectively. The strongest preparation teaches you to manage the whole situation, because that is what instrument flying ultimately demands.
How Leopard Aviation Helps Pilots Prepare for the Written Test and IFR Training
At Leopard Aviation, we treat the written test as one stage in your broader Instrument Rating training. Your goal is not simply to earn a passing score. We help you connect ground knowledge, flight experience, IFR proficiency, and checkride preparation so each stage supports what comes next.
Build the Test Into a Complete Instrument Rating Plan
Your study schedule works best when it fits the rest of your training. We can help you coordinate ground preparation, knowledge-test timing, flight lessons, remaining experience requirements, and eventual practical-test preparation.
That means you are not studying in isolation while your flying develops along an unrelated track. As you work toward your Instrument Rating, concepts you learn on the ground can reinforce what you are beginning to see and do in the cockpit.
Prepare With Experienced Instrument Instructors
Our instrument instructors can help you work through IFR regulations, weather, charts, procedures, navigation systems, aircraft systems, and aeronautical decision-making. If you are using a home-study program, we can also help clarify difficult concepts and identify subjects that deserve more attention.
Once you have completed the required preparation and demonstrated readiness, an appropriately authorized instructor can provide the endorsement needed for the knowledge test. We want you to reach that point understanding the material rather than simply memorizing enough answers to get through the exam.
Apply Written Knowledge in Cessna 172S Skyhawks
You will train in our Cessna 172S Skyhawks equipped with Garmin G1000 avionics, GFC700 autopilot, and ADS-B technology. Thаt gives you a modern environment in which to connect what you studied with what actually happens during IFR operations.
Flight planning, approaches, automation modes, situational awareness, navigation, and equipment failures become much easier to understand when you work with those concepts in the aircraft. The written material stops feeling abstract because you can see how it affects your decisions and workload.
Continue From Written Test to Practical-Test Readiness
Passing the IRA exam is a meaningful milestone, but your training continues. We help you build from instrument-reference aircraft control into clearances, navigation, holds, approaches, missed approaches, weather scenarios, automation management, and complete IFR operations.
Your test result can also reveal areas that need more attention. We can use that information alongside your flight performance to keep strengthening your knowledge and proficiency as you move toward practical-test readiness.
Support for Recent PPL Holders and Transfer Students
You do not need to arrive at exactly the same starting point as every other student. We can work with recent Private Pilot graduates, pilots already studying for the IRA exam, students who have passed it independently, and pilots transferring from another school.
A review of your logbook, knowledge-test status, recent experience, and current proficiency helps us identify the next productive step instead of repeating training you have already completed.
Continue Into Advanced Training
Your Instrument Rating can also be part of a longer aviation path. We support Private Pilot training, Instrument Rating training, Instrument Proficiency Checks, Commercial Pilot training, and CFI training through our flexible Part 61 environment.
If your goals keep growing, the knowledge you build for the written test remаins useful well beyond exam day. It becomes part of the judgment, preparation, and IFR discipline you carry into advanced training and professional aviation.
What Happens if You Do Not Pass?
Not passing the IRA exam is frustrating, but the next steps are straightforward. You’ll receive information showing where your knowledge fell short, complete additional training with an authorized instructor, obtain a new endorsement, and retake the test when you are prepared.
The Failed Report Identifies Areas for Review
Your Airman Knowledge Test Report, or AKTR, shows your score and identifies deficient knowledge areas through applicable ACS codes. Those codes give you and your instructor a much better starting point than simply opening the entire study course again from page one.
Use them to create a targeted review plan. If weather interpretation caused most of the trouble, spend more time there. If your weakness involves procedures or regulations, focus your effort accordingly. Repeating the same question bank without addressing why you missed the material is unlikely to produce the kind of improvement you actually need for IFR flying.
Additional Training Is Required Before Retesting
Under 14 CFR § 61.49, if you fаil a pilot knowledge test, you must receive additional training from an authorized instructor before applying for the retest. That instructor must determine that you are proficient to pass and provide the required endorsement.
This is useful rather than punitive. A knowledgeable instructor can help you separate a genuine knowledge gap from a testing problem and concentrate your preparation where it will make the biggest difference.
Bring the Failed AKTR and Retest Authorization
When you return for the IRA retest, the FAA’s current Airman Knowledge Testing Matrix requires you to present the applicable failed AKTR along with an endorsement from the authorized instructor who provided the additional training and determined that you are prepared to pass. The endorsement can take an acceptable written or logbook form, including the instructor statement on the failed AKTR.
Check the current FAA and PSI requirements before your appointment so you know exactly which documents and identification to bring. Administrative improvisation is rarely the skill anyone hoped to demonstrate at a testing center.
Ready to Take the IRA Exam?
The instrument rating written test is one important checkpoint in your IFR training, not the whole journey. You need the right ground preparation, test authorization, FAA account setup, and a solid grasp of regulations, weather, chаrts, navigation, procedures, systems, and decision-making before exam day. If your first attempt does not go as planned, the FAA also gives you a clear path to review, retrain, and retest.
At Leopard Aviation, we connect written-test preparation with the instrument flying skills you are building in the cockpit. Strong knowledge makes every later stage easier to understand and apply. Schedule your instrument training with us and start turning what you study on the ground into confident IFR decision-making in the airplane.

FAQs
How hard is the instrument rating written test for most pilots?
The exam is very manageable if you prepare consistently, but it demands more than memorizing isolated facts. You need to interpret weather, charts, regulations, navigation information, and realistic IFR scenarios. Many students find the challenge comes from combining several pieces of information quickly. A strong ground-school plan, regular practice, and reviewing why each answer is correct will make the test feel far more predictable.
Do I need to finish all of my Instrument Rating flight training before taking the written test?
No. You can take the knowledge test before completing all of the flight experience required for the Instrument Rating. In fact, many pilots prepare for the written exam while their flight training is still underway. Keeping ground study and cockpit training reasonably aligned can be helpful because the procedures, weather concepts, charts, and regulations you study become easier to understand when you are also seeing them used during IFR lessons.
How does Leopard Aviation help students prepare for the IRA written test?
At Leopard Aviation, we connect your ground preparation with the instrument training you are doing in the airplane. We can help you work through regulations, weather, charts, navigation, systems, procedures, and decision-making while identifying areas that need more attention. If you are using a home-study course, we can also review difficult topics and help determine when you are genuinely ready for the required knowledge-test endorsement.
Can Leopard Aviation help if I already started studying on my own?
Yes. At Leopard Aviation, we can work with you even if you have already completed part of a home-study course or have been preparing independently. We can review where you are, clarify confusing subjects, identify gaps, and connect your study progress with your flight-training plan. You do not need to throw away the work you have already done. We can help you build from it and focus on what still needs attention.
Can Leopard Aviation train me if I already passed the IRA exam elsewhere?
Yes. At Leopard Aviation, we can work with pilots who have already passed the knowledge test before joining us. We can review your test report, logbook, previous instrument experience, and current proficiency to determine the next productive step. Passing the written exam means one major requirement is already complete, but we will still help you strengthen any deficient knowledge areas while building the flight proficiency needed for the practical test.
