The FAA knowledge test is the first big gate on the way to your private pilot certificate, and it is also the one most students underestimate. It is not hard because any single question is hard. It is hard because it covers a lot of ground, and the questions are written to catch the difference between knowing a fact and understanding it. This guide explains exactly how the test works and how to prepare for it.
The Private Pilot Airplane (PAR) knowledge test has 60 multiple-choice questions, a 2.5-hour limit and a 70% passing score (42 correct). It is a computer-based test taken at an approved testing center, after an instructor endorsement. Your result stays valid for 24 calendar months, and your score report lists the knowledge areas you missed.
The Test at a Glance

|---|---|
| Questions | 60, multiple choice |
| Time limit | 2.5 hours (150 minutes) |

Each question has one correct answer out of three options. Many of them refer to a figure: a sectional chart excerpt, a weight and balance table, a performance chart, a VOR indicator, or a METAR. Those figures come in the testing supplement, which the testing center gives you. Learning to read them quickly is a skill of its own, and one of the best investments of your study time.
What the Test Covers
The test is built around the Airman Certification Standards (ACS) for the Private Pilot Airplane certificate. Every question traces back to a knowledge element in the ACS, and your score report lists the ACS codes of the questions you got wrong. For study purposes, the content falls into a handful of areas:
| Area | What to expect |
|---|---|
| Regulations | Pilot certificates, medical requirements, currency, right-of-way, 14 CFR Part 91 operating rules, NTSB reporting |
| Airspace and airport operations | Airspace classes and their requirements, radio communications, airport signs, markings and lighting, traffic patterns |
| Weather | Weather theory, METARs and TAFs, weather advisories, forecasts, and weather hazards |
| Aerodynamics | Lift, drag, stalls, load factor, stability, flight controls |
| Aircraft systems | Engines, fuel, electrical systems, propellers, flight instruments |
| Performance and weight and balance | Density altitude, takeoff and landing performance, weight and balance, center of gravity |
| Navigation and flight planning | Sectional charts, VOR and GPS navigation, wind correction, time, speed, distance and fuel |
| Aeromedical factors and decision making | Hypoxia, illusions, fatigue, risk management, aeronautical decision making |
Before You Can Sit the Test
Two practical steps come before the exam itself:
- Get your endorsement. You need a logbook endorsement from an authorized flight instructor confirming that you have studied the required knowledge areas and are prepared for the test. Students in an approved training course get a graduation certificate instead. Ask your instructor which one applies to you.
- Book your test. Testing is done at approved testing centers, and you schedule through them. Bring a valid photo ID and your endorsement. Check the testing center’s rules when you book: they tell you what to bring, including whether you may use your own flight computer or calculator.
How to Prepare
The students who pass comfortably tend to do the same few things:
- Study from the primary sources first. The FAA’s own handbooks are free and written for this exam: the Pilot’s Handbook of Aeronautical Knowledge, the Airplane Flying Handbook, the Aviation Weather Handbook, and the Aeronautical Information Manual (AIM). Read the relevant chapter before you drill the questions on that subject.
- Practice with questions, then read every explanation. A question you answered correctly by luck teaches you nothing. A question you got wrong and understood teaches you a lot. Read the explanation for the right answer and for the options you rejected.
- Learn to use the figures. Practice with real charts and tables until reading a sectional, a loading graph or a performance chart feels routine. Time yourself.
- Use spaced repetition for the facts that do not change. Numbers such as VFR weather minimums, airspace dimensions and V-speed definitions are best kept fresh with flashcards that return right before you forget.
- Take timed mock exams. Two or three full 60-question runs under a 150-minute clock show you where your time goes and which areas are still weak.
- Review your weak areas, not your strong ones. It is comfortable to keep practicing what you already know. Your mock exam results tell you where the points are.
Test-Day Strategy
You have about 2.5 minutes per question, which is generous. Most people finish with time to spare, so there is no reason to rush.
- Read the whole question and every option before choosing. Wrong options are often written to look right to someone who read half the question.
- Answer the easy ones first. Mark the questions that need a chart or a calculation and come back to them. Everything you answer is points in the bank.
- Use the figure the question names. If the question says “refer to Figure 26”, the answer is in that figure, not in your memory of a similar chart.
- Do not change an answer without a reason. Your first reading is usually right. Change it only if you notice something you missed.
- Use your time to double-check calculations. Weight and balance, wind components and fuel problems are easy to get wrong by a small slip, and the wrong options are built from those slips.
After the Test
When you finish, you get an unofficial result right away, and then your knowledge test report. Keep it: you present it when you take your practical test, and the ACS codes on it show which areas to review with your instructor before the checkride. The report is valid for 24 calendar months, so plan your practical test within that window.
If you do not pass, do not panic. Retesting requires an endorsement from an authorized instructor who has given you additional training (14 CFR 61.49). Your score report is a precise list of what to study. Always confirm the current rules with your instructor and testing center, because requirements can change.
Common Mistakes
- Treating it as a memorization test. The questions test understanding. If you know why a stall speed rises in a turn, you can answer any version of the question.
- Ignoring the charts. Students who do well on theory questions still lose points on chart questions they never practiced.
- Leaving weather for last. Weather is the largest and most variable area. Start it early.
- Not reading the explanations. The explanation is where the learning happens.
Study With AltiPrep FAA
AltiPrep FAA covers all eight areas with over a thousand practice questions, each with a written explanation, plus spaced-repetition flashcards and timed 60-question mock exams in the same format as the real test. The first two subjects are free, so you can see whether it works for you.
This article is a study aid. For official requirements, always check current FAA publications, such as the Airman Certification Standards and 14 CFR, and ask your flight instructor.

Frequently asked questions
How many questions are on the FAA Private Pilot knowledge test?
The Private Pilot Airplane (PAR) knowledge test has 60 multiple-choice questions. You have 2.5 hours (150 minutes) to answer them, and you need 70 percent, which means at least 42 correct answers, to pass.
Do I need an instructor endorsement to take the knowledge test?
Yes, in most cases. You need a logbook endorsement from an authorized flight instructor stating you have studied the required aeronautical knowledge and are prepared for the test, or a graduation certificate from an approved training course. Your instructor can tell you which applies to you.
How long is a passing knowledge test score valid?
Your knowledge test report is valid for 24 calendar months. You must take your practical test (checkride) within that window, or you will have to pass the knowledge test again.
What happens if I fail the knowledge test?
You can retake it. You will need to present your failed test report and an endorsement from an authorized instructor who gave you additional training, as described in 14 CFR 61.49. Your score report lists the knowledge areas you missed, which is the best guide for what to study next.
What materials can I bring and what will I be given?
The testing center provides the FAA Airman Knowledge Testing Supplement, the booklet of charts and figures used by the test questions, plus scratch paper. Rules about calculators and flight computers are set by the testing center, so check with them when you book.
