§ Sources
The sources
The FAA documents this site is built from, what each one is, which parts matter for the UAG test, and the edition or date printed on each.
Checked against the sources 2026-10-26
This site was written from primary documents, not from other study guides. Every rule, number and procedure in the chapters comes from one of the documents below, and each claim carries a citation under it so you can open the source and check. The quiz questions follow the same discipline. Each one names the passage it rests on, and a different reviewer than the author opens that passage and confirms the keyed answer before the question is allowed to ship. All were retrieved on 2026-10-26, and each edition shown is the one printed on the document.
14 CFR Part 107, Small Unmanned Aircraft Systems
The regulation that governs commercial and certificated drone flying. It covers the general and operating rules, certification (subpart C), flying over people (subpart D) and waivers. For the UAG test it is the center of gravity: Regulations alone is 48 percent of the items, and most Operations questions rest on it too. The text used here is the eCFR as current on 2026-10-23, the latest issue date available when it was retrieved. 14 CFR Part 107 (eCFR, current as of 2026-10-23)
14 CFR Part 48, Registration and Marking
Who must register a small drone, how, what it costs ($5.00), how long it lasts (three years), and how the registration number is displayed. Section 48.15, the requirement and its recreational exception, is the one to know. Edition: eCFR as of 2026-10-23. 14 CFR Part 48 (eCFR, current as of 2026-10-23)
14 CFR Part 89, Remote Identification
The rule that makes registered drones broadcast an identity, with three ways to comply: a standard Remote ID aircraft, a broadcast module, or flying inside an FAA-recognized identification area. Sections 89.105 to 89.115 carry most of the test weight. Edition: eCFR as of 2026-10-23. 14 CFR Part 89 (eCFR, current as of 2026-10-23)
14 CFR § 91.113, Right-of-way rules
A single section from the manned-aircraft rules that Part 107 relies on. It says who yields to whom: distress first, then converging aircraft by category, head-on, overtaking and landing. Edition: eCFR as of 2026-10-23. 14 CFR § 91.113
FAA-S-ACS-10B, Remote Pilot ACS
The Airman Certification Standards are the FAA’s list of what the test covers, written as numbered knowledge elements such as UA.I.B.K10. The report you receive after the test lists the codes you missed, and this site tags its questions with the same codes. Edition: 10B, April 2021, effective April 6, 2021. It is still the latest published ACS, and there is no 10C. Its Appendix 1 blueprint, though, is obsolete (see the advisories below). FAA-S-ACS-10B (Apr. 2021)
FAA-G-8082-22, Remote Pilot Study Guide
The FAA’s own study guide, covering regulations, airspace, weather, loading, emergencies and operations in plain prose. Useful for weather and airspace background, but not safe as a sole source: it is dated August 2016, which is before the 2021 amendments, so it says nothing about operations over people, Remote ID or night rules. Use AC 107-2A, Part 89 and the PSI bulletin for those. FAA-G-8082-22 (Aug. 2016)
FAA-CT-8080-2H, Airman Knowledge Testing Supplement
The booklet of figures you are handed at the test center: sectional chart excerpts, legends, weight and balance tables and graphs, and similar. Edition: 2H, 2018, which supersedes 2G of 2016. Since October 26, 2026 some UAG questions use chart images that are not in the supplement. FAA-CT-8080-2H (2018)
AC 107-2A, Small Unmanned Aircraft System
The FAA’s advisory circular on how to read and comply with Part 107. It explains what the rules mean in practice, including certification, the recurrent training cycle, waivers and, in a footnote, the recreational exception. For the test, it is a reference the ACS cites alongside the regulations. Edition: AC 107-2A, dated 2/1/21. It replaced AC 107-2 of 2016, which is cancelled. AC 107-2A (2/1/21)
UAG sample questions
Forty-six sample questions with their ACS codes, from the FAA. The FAA says they are study material and not necessarily actual test questions. Edition: dated 8/10/2021, so they predate the image-based questions added in 2026. FAA UAG Sample Airman Knowledge Test Questions (8/10/2021)
The FAA Airman Knowledge Testing Matrix
A table of every FAA knowledge test, with its length, minimum age, time and passing score. The UAG row says 60 questions, age 14, 2.0 hours and a passing score of 70, requires no instructor endorsement, and notes that the report prints ACS codes (not learning statement codes). Edition: September 25, 2026. For the learning statement codes of other tests, the FAA’s Learning Statement Reference Guide of September 27, 2021 is the latest version it links, but it is not needed for the UAG. FAA Airman Knowledge Testing Matrix (Sept. 25, 2026), p. 15
The PSI UAG Applicant Information Bulletin
The only source for the current blueprint and for the test-center rules, hosted by PSI, the FAA’s testing vendor. It has the scheduling, identification and security rules, and the test specification on page 4: 60 scored questions, 5 unscored, 120 minutes, 70 percent. Edition: effective September 29, 2025. It is the one document here not hosted on faa.gov, but the FAA’s August 2025 advisory directs applicants to it. PSI UAG Applicant Information Bulletin (eff. 2025-09-29)
The Pilot’s Handbook of Aeronautical Knowledge
FAA-H-8083-25C (2023), the general-aviation textbook. The ACS cites it, and this site draws on eight chapters: Chapter 2 on aeronautical decision-making, Chapter 10 on weight and balance, Chapter 11 on aircraft performance, Chapter 12 on weather theory, Chapter 13 on aviation weather services, Chapter 15 on airspace, Chapter 16 on navigation (which includes sectional charts) and Chapter 17 on aeromedical factors. A December 2024 advisory committee memo reportedly flags outdated content in some chapters, such as the weather depiction charts in Chapter 13, so cross-check those against the Aviation Weather Handbook. FAA-H-8083-25C (2023)
- Ch. 2, Aeronautical Decision-Making
- Ch. 10, Weight and Balance
- Ch. 11, Aircraft Performance
- Ch. 12, Weather Theory
- Ch. 13, Aviation Weather Services
- Ch. 15, Airspace
- Ch. 16, Navigation
- Ch. 17, Aeromedical Factors
FAA-H-8083-28B, Aviation Weather Handbook
The technical reference for weather products: METARs, TAFs, charts and the physics behind them. The UAG test asks about reading reports and forecasts and about weather effects on a small drone, so the chapters on observations and forecasts matter, and the rest is background. Edition: 28B, 2026, published 04/02/2026 according to the FAA’s page. FAA-H-8083-28B (2026)
The Aeronautical Chart Users’ Guide
The legend for aeronautical charts: every symbol on a sectional, explained, including airports, airspace boundaries, obstacles and radio aids. The test expects you to read a chart you may never have seen, and the legend decodes it. Edition: effective as of 9 July 2026. FAA Aeronautical Chart Users' Guide (eff. 9 July 2026)
FAASafety.gov courses
The online courses behind recurrent training: ALC-677, “Part 107 Small UAS Recurrent” for most pilots, ALC-451 for Part 61 pilots taking the initial course in place of the test, and ALC-515 for Part 61 pilots’ recurrent training. They are not on the test, but they define how you keep the certificate.
The two advisories, and what changed
Two editions of the FAA’s Airman Testing Community Advisory changed the UAG test.
August 2025. The FAA announced that a scientific assessment of the UAG exam would take effect on September 29, 2025, making the blueprint in ACS-10B obsolete and pointing applicants to the PSI bulletin until the ACS is updated. Topics and subject matter did not change, and the time allotment was not reduced. FAA Airman Testing Community Advisory, August 2025, pp. 3 and 4 Read the August 2025 advisory.
September 2026 Special Edition. Beginning October 26, 2026, the UAG test includes image-based questions whose images are not in the printed supplements, drawn from current sectional charts. The date was corrected from an earlier edition that said October 27. The FAA will not preview the images, has not yet described any on-screen tools, and says the supplement stays available until it announces a removal date. FAA Airman Testing Community Advisory, September 2026 Special Edition, pp. 4 to 6 Read the September 2026 special edition.
For the test-day details, see the test-day chapter.
Aeronautical Information Manual (AIM), selected sections
The FAA’s official guide to flight information and ATC procedures, written for manned pilots and updated several times a year. Three sections carry material the UAG test draws on and that nothing else in this list states outright: Chapter 4, Section 3 (airport operations: the traffic pattern, standard left turns, pattern altitude, the segmented circle and wind indicators), Chapter 2, Section 3 (runway markings: designators from magnetic azimuth, displaced thresholds, the closed-runway X), and Chapter 4, Section 1 (traffic advisory practices at airports without a tower: CTAF, UNICOM, MULTICOM, and self-announce phraseology). Questions and lessons cite these as “AIM 4-3-3” and so on. The FAA publishes the AIM as web pages; the edition read for this site is the current one as of October 2026.
