Private Pilot Written Test: Subjects, Codes and Scoring

The private pilot airplane knowledge test, FAA test code PAR, is 60 scored questions plus 5 unscored validation questions, 120 minutes, and a passing score of 70 percent. In 2025 it was taken 44,657 times, 89.56 percent of them passes, with an average score of 81.64 percent. What is on it is not a secret. Every question maps to a knowledge element in the Private Pilot for Airplane Category Airman Certification Standards, FAA-S-ACS-6C, and the code for every question you miss is printed on your test report, which your examiner reads before your checkride.

The test at a glance

The numbers below come from the FAA Airman Knowledge Testing Matrix dated September 25, 2026, which supersedes the October 22, 2025 version, and from PSI's Private Pilot Airplane applicant information bulletin. The two agree. The table printed inside the ACS itself does not, on one number.

Sources: the FAA Airman Knowledge Testing Matrix, PSI's PAR applicant bulletin, the FAA's allotted-time correction table, PSI's FAA testing page, and the eCFR for 61.35, 61.103 and 61.39.

One trap on time. Appendix 1 of FAA-S-ACS-6C prints a table giving the PAR test 2.5 hours. The FAA's separate correction table says that figure is wrong and the allotted time has been 2.0 hours since April 24, 2023, and the September 2026 matrix agrees. Plan for 120 minutes. The PSI bulletin says that includes the time to answer the 5 validation questions, new items being trialed that do not count for or against you.

The authorization is a logbook endorsement. Under 14 CFR 61.103(d) it comes from an authorized instructor who either conducted your ground training or reviewed your home study on the knowledge areas in 61.105(b), and who certifies you are prepared for the test. The identification requirement is in 61.35(a): a photo, a signature and a date of birth. A graduation certificate from a Part 141 pilot school works in place of the endorsement.

What subjects are on the private pilot written test?

The private pilot written test covers the 13 aeronautical knowledge areas in 14 CFR 61.105(b), organized and weighted by the Areas of Operation in FAA-S-ACS-6C, with Preflight Preparation alone carrying 22 percent of the questions. The regulation lists the subjects. They start with the applicable regulations, NTSB accident reporting, use of the AIM and advisory circulars, VFR charts and navigation by pilotage, dead reckoning and navigation systems, and radio communications. Then weather: recognition of critical weather situations and the use of weather reports and forecasts. Then the airplane: collision and wake turbulence avoidance, density altitude effects, weight and balance, aerodynamics, powerplants and systems, and stall and spin awareness. Then judgment: aeronautical decision making, and preflight action including runway lengths, performance data and fuel requirements.

Thirteen areas, one test, and the weighting is not even.

The ACS turns that list into Areas of Operation that align with 14 CFR 61.107(b), and PSI's bulletin publishes how much of the test each one carries, based on a job task analysis completed in 2020.

Percentages are from PSI's Private Pilot Airplane applicant information bulletin, checked October 2026; task names are from the table of contents of FAA-S-ACS-6C. Area X, Multiengine Operations, does not appear in the PAR specification.

Read the weights before you plan your study time. Preflight Preparation and Takeoffs, Landings and Go-Arounds together are 42 percent of the test, roughly 25 of 60 questions. Weather, airspace, performance charts, weight and balance and cross-country planning all live in the first area; if a raw report still looks like noise, start with how to read a METAR and VFR weather minimums by airspace. The maneuvers that take up most of your flight lessons, steep turns and ground reference, are 3 percent, about 2 questions.

How do ACS codes work on your test report?

An ACS code on your Airman Knowledge Test Report identifies the exact knowledge element behind each question you missed, in the format ACS, Area of Operation, Task, element, so PA.IX.A.K3 means Private Pilot Airplane, Area IX, Task A, Knowledge element 3 (FAA-S-ACS-6C, Appendix 1). Look that one up and you find Area IX is Emergency Operations, Task A is Emergency Descent, and K3 reads "Airspeed, including airspeed limitations."

The codes matter after the test, not just on it. Before the practical test your instructor must endorse that you have "demonstrated satisfactory knowledge of the subject areas in which the applicant was deficient on the airman knowledge test" (14 CFR 61.39(a)(6)(iii)). The ACS then hands the examiner the same list: among the minimum elements an evaluator must test in each task are "any elements in which the applicant was shown to be deficient on the knowledge test" (FAA-S-ACS-6C, Appendix 1). That is why the FAA tells you to keep the original report "so an evaluator may review any noted areas of deficiency, with you, during the oral portion of your practical test" (FAA testing FAQ, updated June 1, 2026).

In plain terms: a 73 (44 of 60) is a pass, and it is also a list of 16 topics the examiner has been told to ask you about. Treat the report as the first page of your oral prep. Our opinion is that a student who scores in the 90s has bought a shorter, calmer oral exam, which is worth more than the number itself.

Not every FAA test prints ACS codes yet. The September 2026 Airman Testing Community Advisory notes that 33 of the 91 FAA knowledge tests now show ACS codes on the report. The PAR test does. That is why the FAA's own most-missed report for it is written in ACS codes rather than the older learning statement codes.

The most-missed code is about airspeed in an emergency

The FAA's own quarterly report, Frequently Missed Knowledge Test ACS Codes for the second quarter of calendar 2025, covering July 1, 2024 through June 30, 2025, lists one code for the private pilot airplane test: PA.IX.A.K3, missed 73.33 percent of the time (FAA, Frequently Missed Knowledge Test ACS Codes, 2Q CY25). The report's threshold is strict. According to the September 2026 Airman Testing Community Advisory, it includes only ACS codes administered at least 100 times and displays only those missed more than 70 percent of the time.

For the private test, exactly one code cleared that bar.

That code is the airspeed knowledge element under Emergency Descent. Flight Training Central's February 27, 2026 summary of the FAA data reads it as knowing critical speeds, best glide, maneuvering speed and the limitations tied to aircraft configuration (Flight Training Central, February 2026). That is a secondary source interpreting a one-line FAA table, so weigh it as such. The mechanism behind the miss rate is easy to guess and hard to prove: students memorize a handful of V-speeds for one trainer and are then asked which speed applies to which emergency, which is a different skill.

Sporty's practice-test data points the same way. In June 2026 it reported that its most-missed questions in spring 2026 were on fundamentals: airport signs and markings, taxi technique in wind, how true altitude differs from indicated in nonstandard temperature, and the order of operations in an unusual attitude recovery (Flight Training Central, June 5, 2026). Those are practice-test statistics, not FAA statistics, and we have not reproduced the questions.

The misses cluster on material everyone thinks they already know.

Scores and pass rates in 2024 and 2025

Seventy percent is 42 correct answers out of 60. The FAA's annual statistics put the 2025 private pilot airplane numbers at 44,657 tests, an 89.56 percent pass rate, and an 81.64 percent average score (FAA, 2025 Airman Knowledge Test Statistics); in 2024 the figures were 46,132 tests, a 91.90 percent pass rate and an 82.89 percent average (FAA, 2024 Airman Knowledge Test Statistics). Volume fell by about 1,500 tests. The pass rate slipped a little over two points.

Two cautions. The pass rate counts tests, not people, so a candidate who fails and then passes appears twice. The FAA has said nothing public about why the rate moved, so a one-year change of two points is not a trend, and anyone selling you a course on the strength of it is selling.

If you fail, 14 CFR 61.49(a) requires additional training from an authorized instructor and a new endorsement before you can retest, and PSI charges the $175 again; the rest of the training budget is in how much a private pilot license costs. When you present the failed report as your retest authorization, the proctor scans it and destroys it, per the matrix. Photograph it first.

Study to the ACS, not to a question bank

Open FAA-S-ACS-6C to the first Area of Operation and read the knowledge elements under each task. Every line that starts with a K is something the FAA has said it may ask you, and every question on the knowledge test maps back to one of those lines. The FAA does not release live questions, and its testing FAQ says it continuously adds, reviews and revises them (FAA testing FAQ), which is why a memorized bank goes stale while the ACS does not. Work through the elements with the Pilot's Handbook of Aeronautical Knowledge open beside you, and mark each one you can explain to another person without notes.

Weight your time by the table above. Spend the most on Preflight Preparation and Takeoffs, Landings and Go-Arounds, then Preflight Procedures, then Navigation and Slow Flight and Stalls. Give Emergency Operations more than its 7 percent suggests, since the single most-missed code lives there.

Use practice tests to find holes, not to learn. A free sample test is available on PSI's site under Exam Resources, and the FAA's companion guide, FAA-G-ACS-2 with Changes 1 and 2, suggests marking difficult questions for later review and answering every question before time expires (FAA-G-ACS-2). When a practice question beats you, do not memorize the answer. Find the ACS element it belongs to, read the handbook section, and move on.

Take the test early. The report is good for 24 calendar months before the practical test (14 CFR 61.39(a)(1)(i)), so passing it in your first few months of training costs nothing and frees your flight lessons from theory. A home-study course satisfies the knowledge requirement (61.105(a)), so the endorsement does not require a classroom.

Scheduling, identification and test day

Scheduling runs through PSI, the FAA's testing contractor. You need an FAA Tracking Number first, which comes from creating a profile in IACRA, then a PSI account (FAA-G-ACS-2, Section 1). PSI's bulletin says you may cancel and reschedule if notice is received 24 hours before the appointment, recommends arriving 15 minutes early, and warns that arriving after the start time can forfeit the fee.

Bring identification with a photo, a signature, a date of birth and a physical residential address, plus your endorsement. The test center supplies the supplement book, scratch paper and a writing instrument; you may bring your own plotter, flight computer and a calculator without permanent memory. Phones, watches, notes and hats stay outside. The report prints when you finish.

What changed recently

The FAA publishes changes in its Airman Testing Community Advisory. The September 2026 special edition has three items that touch this test. The matrix was reissued on September 25, 2026 with clearer language on added-rating tests. The Graphics Conversion Project now embeds images directly in private pilot questions, with the printed supplement still provided during the transition and no date yet set for removing it. And PSI is moving its exams to a new Test Taker Portal. Content and standards are unchanged. The running changelog is in FAA written test changes in 2026.

Once you pass, put the report with your logbook, not in a drawer. Your instructor needs it to write the 61.39 endorsement, and your examiner will read it before the oral. A free digital logbook keeps your training time organized so that endorsement can be written against an accurate record. The codes on the report tell you what to review first. Start there.
