Private Pilot Airman Certification Standards Are the FAA's Rulebook for What You Must Know and Do to Earn Your License
The Airman Certification Standards (ACS) for private pilot are a detailed document published by the Federal Aviation Administration that spells out exactly what knowledge, skills, and risk management abilities you must demonstrate to pass your checkride. They are not a study guide or a suggestion — they are the official standard that examiners use to evaluate whether you are ready to fly an aircraft without an instructor on board.
The private pilot ACS covers three broad areas: the knowledge you need (called the "knowledge test"), the practical flying skills you need (called the "practical test" or checkride), and the decision-making and judgment you need to stay safe. Each area is broken down into specific tasks, and each task lists exactly what you must be able to do, what conditions you will be tested under, and what counts as acceptable performance.
The document itself is free and available on the FAA website. Most flight schools and instructors use it to structure their training, and examiners carry it during checkrides to score your performance. Understanding what is in it before you start training — or before you take your checkride — saves time and prevents surprises.
Key Takeaways
- The Airman Certification Standards are the FAA's official list of what you must know and be able to do to earn a private pilot license, broken into knowledge, skills, and judgment areas.
- The document covers 18 major task areas, from preflight inspection and aircraft systems to navigation, emergency procedures, and decision-making in bad weather.
- Examiners use the ACS to score your written test, your oral exam, and your flying during the checkride, so meeting the standard in each task is required to pass.
- The ACS is updated periodically by the FAA, and the version in effect when you take your checkride is the one that applies to you.
- You can read the current ACS for free from the FAA's website and use it to track your progress during flight training.
The Three Sections of the Private Pilot ACS
The ACS is organized into three main parts. The first part covers knowledge — the information you must know to pass the written test and the oral portion of your checkride. This includes aircraft systems, weather, navigation, regulations, and aerodynamics. The FAA publishes a separate study guide called the Airman Knowledge Test Study Guide, and the questions on the written test come from the topics listed in the ACS.
The second part covers skills — the flying tasks you must perform during your practical test. These include preflight inspection, takeoff and landing, slow flight, stalls, emergency procedures, and navigation. Each task describes the exact conditions under which you will be tested (for example, "with a 10-knot crosswind" or "at 1,500 feet above ground level") and what constitutes acceptable performance.
The third part covers risk management and judgment. This is the decision-making side of flying — knowing when not to fly, how to recognize hazards, and how to manage them. The ACS lists specific scenarios and decisions you may be asked about during your oral exam, such as what you would do if weather deteriorated during a flight or if you discovered a mechanical problem before takeoff.
The 18 Task Areas You Will Be Tested On
The private pilot ACS breaks down into 18 major task areas. You will not necessarily be tested on all of them during your checkride — the examiner selects a subset — but you must be prepared for any of them. The tasks are organized roughly in the order a pilot would encounter them during a flight: preflight, startup, taxi, takeoff, navigation, and landing, plus emergency procedures and special operations.
The first few tasks cover the ground: preflight inspection, aircraft systems and powerplant, cockpit management, and engine starting. The middle tasks cover flying: takeoff, climb, cruise, descent, approach, and landing. Later tasks cover navigation, slow flight, stalls, emergency procedures, and operations in different conditions such as crosswinds or soft-field landings. The final tasks cover special situations such as operations at high-altitude airports or operations near mountains.
Each task includes a list of specific knowledge points you must understand. For example, the preflight inspection task requires you to know what to look for on the exterior and interior of the aircraft, what defects are airworthy and which are not, and how to document your inspection. The examiner will ask you about these points during your oral exam and may ask you to actually perform parts of the inspection during your practical test.
How Examiners Use the ACS During Your Checkride
During your checkride, the examiner will have a copy of the ACS and will use it to score your performance on each task. The examiner is looking for whether you meet the standard, exceed it, or fall short. Meeting the standard means you perform the task safely and competently, with only minor errors that do not affect safety. Exceeding the standard means you perform it smoothly and with good judgment. Falling short means you make errors that affect safety or show a lack of understanding.
The checkride itself has three parts: the oral exam (also called the "knowledge test"), the preflight inspection and systems review, and the flight test. During the oral exam, the examiner will ask you questions based on the knowledge section of the ACS. During the preflight and systems review, you will demonstrate your understanding of the aircraft and your ability to conduct a thorough inspection. During the flight test, you will perform the flying tasks listed in the ACS while the examiner observes and scores your performance.
If you do not meet the standard on any task, you will not pass that portion of the checkride. You can retake the failed portion at a later date, usually within 60 days. You do not have to retake the entire checkride, only the portion you failed.
Knowledge Test Topics Covered in the ACS
The knowledge section of the ACS lists the topics you must understand to pass the written test and the oral exam. These topics include aircraft systems (engines, fuel, electrical, hydraulic, flight controls), aerodynamics (lift, drag, stalls, spins), weather (cloud types, wind shear, thunderstorms, icing), navigation (charts, compass, GPS, dead reckoning), regulations (airspace, right-of-way, medical certificates), and human factors (fatigue, stress, decision-making).
The ACS does not provide the answers to these topics — it only lists what you need to know. You learn the material through flight training, study guides, textbooks, and online courses. The FAA publishes the Airman Knowledge Test Study Guide, which covers all the topics and is the primary resource most pilots use to prepare for the written test. Many flight schools also provide their own study materials and practice tests.
The written test itself is administered by a testing center and consists of 60 multiple-choice questions. You have two hours to complete it. A passing score is 70 percent or higher. The test is based on the topics in the ACS, so studying the ACS and the study guide will prepare you for the test.
Practical Flying Tasks and Performance Standards
The practical test section of the ACS lists 18 flying tasks and describes what you must be able to do in each one. For each task, the ACS specifies the conditions under which you will be tested (such as wind speed, altitude, or visibility), the exact maneuver or procedure you must perform, and the standards for acceptable performance.
For example, the "Takeoff and Climb" task requires you to perform a normal takeoff, a crosswind takeoff, and a soft-field takeoff. For each one, the ACS specifies that you must maintain directional control, achieve the correct pitch attitude, retract the landing gear and flaps at the right time, and climb at the correct airspeed. The examiner will score you on whether you meet these standards during the flight test.
The "Approach and Landing" task requires you to perform a normal approach and landing, a forward slip to a landing, a go-around, and a soft-field landing. Again, the ACS specifies the exact conditions and standards for each one. The examiner will observe your performance and score whether you meet the standard.
Risk Management and Decision-Making in the ACS
A newer addition to the ACS is the emphasis on risk management and decision-making. The FAA recognizes that many accidents happen not because pilots lack skills, but because they make poor decisions — such as flying into bad weather, flying when fatigued, or continuing a flight when something feels wrong.
The ACS includes a section on risk management for each task. For example, under the "Preflight Planning" task, the risk management section asks you to identify hazards such as weather, runway conditions, and fuel reserves, and to decide whether the flight is safe to conduct. During your oral exam, the examiner may ask you scenario questions such as "You are planning a 200-mile flight and the weather forecast shows thunderstorms along your route. What would you do?" Your answer should show that you understand the hazard and know how to manage it.
The ACS also includes a section on aeronautical decision-making (ADM), which is a structured way of thinking about risk and making safe choices. The examiner may ask you about ADM concepts during your oral exam or may present you with scenarios during the flight test to see how you respond to unexpected situations.
How to Use the ACS During Your Training
The ACS is a tool you can use throughout your flight training to track your progress and know what to expect on your checkride. Most flight schools provide a copy to their students, and you can also read it for free from the FAA website. As you complete each task during training, you can check it off in the ACS and make notes about areas where you need more practice.
Before your checkride, review the ACS to make sure you understand all the tasks and standards. Read through the knowledge section and make sure you can answer the questions. Review the practical test section and visualize yourself performing each task. Review the risk management section and think about how you would handle the scenarios described.
During your training, ask your instructor to explain any part of the ACS that is unclear. Your instructor should be using the ACS to structure your training and should be able to tell you exactly what you need to know and be able to do to pass your checkride.
When the ACS Is Updated and How It Affects You
The FAA updates the ACS periodically to reflect changes in regulations, technology, or training practices. Updates are usually announced on the FAA website and take effect on a specified date. If you are in the middle of training when an update occurs, your instructor will let you know what has changed.
The version of the ACS in effect on the date of your checkride is the one that applies to you. If the ACS is updated between the time you start training and the time you take your checkride, you will be tested on the new version. This is another reason to check the FAA website before your checkride to make sure you have the current version.
Frequently Asked Questions
Can I read the ACS for free, or do I have to buy it?
The ACS is free and available on the FAA website. You can read it as a PDF and print it or read it on your computer. Your flight school may also provide a copy. There is no reason to pay for it.
Do I have to memorize the entire ACS before my checkride?
No. You need to understand the material and be able to demonstrate the skills, but you do not need to memorize the document word-for-word. Your instructor will help you learn the material through training and study. The ACS is a reference tool to help you know what to expect, not a memorization exercise.
What if my examiner asks me something that is not in the ACS?
The examiner is required to base questions and tasks on the ACS, so this should not happen. If you are unsure about an answer, say so and ask the examiner to clarify. If you believe a question is outside the scope of the ACS, you can raise this concern after your checkride.
Does the ACS cover everything I need to know to be a safe pilot?
The ACS covers the minimum standards required to earn a private pilot license. Being a safe pilot requires ongoing learning, judgment, and experience beyond what the ACS requires. After you earn your license, you will continue to learn through experience and additional training.
How long does it take to meet all the standards in the ACS?
The FAA requires a minimum of 60 hours of flight training, but most pilots need 70 to 100 hours to meet all the standards in the ACS and be ready for their checkride. The time varies depending on your aptitude, how often you fly, and the quality of your instruction. Your instructor can give you a better estimate based on your progress.
