An FAA document used to communicate a means to evaluate the aeronautical knowledge standards for certification knowledge testing for a Remote Pilot Certificate with sUAS rating.
The following web pages web pages (Test Prep 1- 14) are aimed at preparing you for the Remote PIC with sUAS rating written certification knowledge test.
FAA views ACS as the foundation of its transition to a more integrated and systematic approach to airman certification.
ACS is part of the safety management system (SMS) framework that the FAA uses to mitigate risks associated with airman certification training and testing
ACS, associated guidance, and test question components of the airman certification system are constructed around the four functional components of an SMS:
1. Safety Policy - aeronautical knowledge, risk management, and flight proficiency as integrated components of the airman certification system;
2. Safety Risk Management - processes through which both internal and external stakeholders identify changes in regulations, safety recommendations, or other factors. These changes are then evaluated to determine whether they require modification of airman testing and training materials;
3. Safety Assurance - processes to ensure the prompt and appropriate incorporation of changes arising from new regulations and safety recommendations; and
4. Safety Promotion - ongoing engagement with both external stakeholders (e.g., the aviation training community) and FAA policy divisions
Historical Documents (for potential reference)
Feb 2012 - FAA Modernization and Reform Act (FMRA) - PL 112.95
PL 112-95, Title III, Subtitle B. In 2012, Congress passed the FAA Modernization and Reform Act of 2012, PL 112-95. Section 333 of PL 112-95 directed the Secretary of Transportation to determine whether UAS operations posing the least amount of public risk and no threat to national security could safely be operated in the NAS and, if so, to establish requirements for the safe operation of these systems in the NAS. As part of its ongoing efforts to integrate UAS operations in the NAS and in accordance with
Section 333, in June 2016, the FAA issued a final rule adding part 107, integrating civil small UAS into the NAS. Part 107 allows small UAS operations for many different purposes without requiring airworthiness certification, exemption, or a Certificate of Waiver or Authorization (COA).
June 2016 - FAA finalized 14 CFR 107 (624-page document) governing commercial UAS operations in the U.S.
Organization of Part 107. The FAA addresses aviation safety in three key areas: personnel, equipment, and operations. The FAA assesses each of these areas both independently to meet current regulations and standards, as well as collectively to ensure no conflicts exist overall that would create an unsafe condition. This approach allows the FAA to be flexible in responding to the needs of the aviation community while still being able to establish standards for future growth and development. To that end, part 107 contains subparts that focus on each of these key aviation safety areas specific to small UAS, and the chapters in this AC are organized in the same manner.
July 2016 - FAA Extension, Safety, and Security Act (FESSA) - PL 114-190
Aug 2016 - 14 CFR 107 went into effect
3-page summary - quicker read but scarce in detailed knowledge

Oct 2018 - FAA Reauthorization Act - PL 115-254
July 2020 - FAA ORDER JO 7200.23B - went into effect

1.1 Purpose of This Advisory Circular (AC). This AC provides guidance in the areas of airman (remote pilot) certification, aircraft registration and marking, aircraft airworthiness, and the operation of small Unmanned Aircraft Systems (UAS) in the National Airspace System (NAS) to promote compliance with the requirements of Title 14 of the Code of Federal Regulations (14 CFR) part 107.
1.1.1 Effects of Guidance. The contents of this document do not have the force and effect of law and are not meant to bind the public in any way. This document is intended only to provide clarity to the public regarding existing requirements under the law or agency policies. It does not provide, nor is it intended to provide, a legal interpretation of the regulations. This AC uses mandatory terms, such as “must,” when the language is describing an established statutory or regulatory requirement. This AC does not change, add to, or delete regulatory requirements or authorize deviations from regulatory requirements or restrictions.
1.1.2 Part 107 Provisions. This AC is not intended to cover every provision of part 107. Rather, this AC is intended to provide guidance on those provisions of part 107 where additional information may be helpful. The Federal Aviation Administration (FAA) emphasizes, however, that persons subject to part 107 are responsible for complying with every applicable provision of part 107, regardless of whether the provision is discussed in this AC.
1.1.3 Privacy-Related Laws. Part 107 operators should be aware that State and local authorities may enact privacy-related laws specific to UAS operations. The FAA
encourages small UAS operators to review those laws prior to operating
their UAS. The National Telecommunications and Information Administration (NTIA) has also published the Voluntary Best Practices for UAS Privacy, Transparency, and
May 18, 2016). This document outlines and describes voluntary best practices that small UAS operators could take to advance UAS privacy, transparency, and accountability for the private and commercial use of UAS.
The goal of the airman certification process is to ensure the applicant possesses knowledge consistent with the privileges of the Remote Pilot Certificate with sUAS rating, as well as the ability to manage the risks of flight in order to act as a remote PIC.
In fulfilling its responsibilities for the airman certification process, the FAA Flight Standards Service (AFS) plans, develops, and maintains materials related to airman certification testing. These materials include several components.
Other materials, such as airman knowledge testing supplements in the FAA-CT-8080 series and FAA online training, provide guidance to applicants on aeronautical knowledge and risk management.
FAA recognizes that safe operations in today's complex National Airspace System (NAS) require a more systematic integration of aeronautical knowledge and risk management. FAA further recognizes the need to more clearly calibrate knowledge and risk management to the level of the Rmeote Pilot Certificate with sUAS rating.
The ACS integrates the elements of knowledge and risk management in 14 CFR Part 89 and 14 CFR Part 107 for a Remote Pilot Certificate with sUAS rating. It thus forms the comprehensive standard for what an applicant knows and considers to successfully complete eash Task tested on the knowledge test.
In keeping with this integrated and systematic approach, the knowledge Task elements of each Task identify what the applicant should know and understand for sUAS operations conducted under 14 CFR Part 89 and 14 CFR Part 107. The applicant demonstrates this understanding by passing the knowledge test.
ACS includes Areas of Operation and Tasks for the Issuance of a Remote Pilot Certificate with sUAS rating in accordance with 14 CFR 107.65.
Each Area of Operation is further broken down into Tasks
Each Task is coded according to a scheme that includes 4 elements
The elements are then even further broken down into Task Element Knowledge
UA = Applicable ACS (Unmanned Aircraft Systems)
I = Area of Operation (Regulations)
B = Task (Operating Rules)
K10 = Task Element Knowledge 10 (Visual line of sight (VLOS) aircraft operations)
At the conclusion of a knowledge test, an applicant is given their Knowledge Test Report (KTR) which lists the applicant's name, date of the test, the type of test, a unique test identification number, the score, and ACS Codes for questions that were answered incorrectly. The printed ACS Codes guides the applicant to the area(s) that were found to be deficient in the test. The codes are found in April 2021 - FAA-S-ACS-10B - Remote Pilot - sUAS - Airman Certification Standards (ACS).
FAA encourages applicants to use the ACS as a reference while preparing for the certification airman knowledge test.
For those applicants who do not pass the knowledge test for certification, remedial instruction and an enforsement from an instructor is NOT required for retesting.
Applicants who do not meet the requirements in 14 CFR 107.61(d)(2) must pass the knowledge test before applying for a Remote Pilot Certificate with an sUAS rating.
