FAA IRA
·Updated August 2026
IRA Knowledge Test — Study Plan from the Free FAA Corpus
Instrument study adds IFR procedures, instrument flying, navigation, and weather. Our ACS text comparison found no PAR match for about 62% of IRA elements. This measures wording, not exam questions. exclam.ai organizes readings from the IFH, IPH, and Aviation Weather Handbook into a study plan.
Test format
60 multiple-choice questions, 2.0 hours, passing score 70%. Taken at PSI testing centers, with embedded images and access to CT-8080-3F until its announced removal. Non-scored validation questions may be added; the allotted time accounts for them.
About 38% of IRA ACS element texts matched PAR in our comparison; about 62% did not. These approximate text matches do not establish exam weighting.
IFH, IPH, AWH, and PHAK support instrument study. Include the regulations, charts, and other references identified by the applicable ACS.
Practice approach plates and en route charts, including the FAA’s embedded-image samples. From October 26, 2026, IRA includes image questions outside CT-8080-3F.
CY2025: 27,143 tests, 94.38% pass rate, 86.15% average score (FAA AKT Volume Report). The IRA passing score is 70%. Verify current testing details at faa.gov/training_testing before scheduling.
IRA already uses embedded images. Starting October 26, 2026, some image questions use charts outside CT-8080-3F. Printed supplements remain available until the FAA announces their removal. See the August 2026 FAA testing advisory.
IRA knowledge areas
These study topics summarize the FAA Airman Certification Standards and source handbooks. Consult the applicable standards and references for the complete requirements.
IFR Regulations and Procedures
The 14 CFR 91 instrument rules: currency, equipment, altitudes, clearances, and alternates.
Flight Instruments and Attitude Instrument Flying
How the gyros, pitot-static system, and electronic displays work — and fail.
IFR Navigation and Instrument Approaches
En route navigation, holding, and flying every approach type on the plate.
Weather Theory, Products, and Hazards
The weather half of the instrument written, from icing physics to prog charts.
ADM and Aeromedical Factors
Spatial disorientation and decision-making under IMC stress.
exclam.ai does not reproduce FAA test questions. Area names and focus points above are paraphrased from the publicly published ACS at faa.gov.
Free FAA corpus for the IRA
These official FAA handbooks and standards provide a starting source list. The ACS also references regulations, the AIM, advisory circulars, charts, and aircraft-specific POH/AFM material. Use the references applicable to your test alongside these documents.
The core instrument text: flight instruments, attitude instrument flying, navigation systems, and IFR flight fundamentals.
Departures, en route procedures, arrivals, and instrument approaches as actually flown in the IFR system.
The consolidated weather reference — theory, hazards, and every weather product the ACS references.
The base aeronautical-knowledge text: aerodynamics, systems, performance, airspace, navigation, and weather theory.
The official test blueprint: every IRA question maps to a knowledge element in this document.
How exclam.ai helps with the IRA
Study the real handbooks
The FAA PDFs above are free to study. Upload them with the additional references your test requires, and exclam.ai builds a reading plan.
Quizzes mapped to the source
Practice questions and quick checks generated from the handbooks themselves, mapped to the 5 IRA knowledge areas. Every answer traces back to a page.
A dated daily plan
~66 hours of weighted coverage paced to your test date, with review of weak areas and recomputation when you fall behind.
IRA questions
How long should I study for the IRA written?
Allow 6-10 weeks as a starting planning estimate, then adjust for your knowledge and practice results. The suggested plan has about 66 hours of reading and practice. This is a study estimate, not an official exam weighting.
How hard is the IRA compared to the private written?
CY2025 pass rates were 94.38% for IRA and 89.56% for PAR. IRA’s average score was 86.15%. These results describe different candidate groups; they do not establish relative difficulty or explain why candidates pass.
Which handbook matters most?
The Instrument Flying Handbook (IFH) is the core text, but weather carries a large question share — do not leave the Aviation Weather Handbook to the last week.
Is the FAA corpus really enough without a paid course?
The FAA handbooks are a foundation, not a complete source list by themselves. The ACS also references regulations, the AIM, advisory circulars, charts, and aircraft-specific POH/AFM material. Use the applicable references and practice results to check your preparation.
