The documents we build from
Every question explanation and study guide on this site cites one of the documents below. Each was downloaded and checked on September 13, 2026, and you can open every one of them yourself.
FAA and eCFR material is a work of the U.S. Government and isn't subject to copyright (17 U.S.C. 105). The FAA's testing FAQ confirms that its testing standards documents may be copied without permission. The PSI bulletin is PSI's own document, and we cite it for facts only.
Regulations
The rules themselves, from the electronic Code of Federal Regulations. Title 14 was current as of September 10, 2026 when we checked it. Where guidance and regulation disagree, the regulation wins.
- 14 CFR part 107, Small Unmanned Aircraft Systems eCFR current §107.5 has been reserved since November 3, 2025.
- 14 CFR part 89, Remote Identification of Unmanned Aircraft eCFR current
- 14 CFR part 48, Registration and Marking Requirements for Small Unmanned Aircraft eCFR current
- 14 CFR 91.17, 91.19, 91.137 and 91.203 eCFR current Part 107 pulls these in for alcohol and drugs, flight restrictions and registration.
- 14 CFR part 3, General Requirements (falsification, §§3.401 to 3.405) eCFR current Replaced §107.5, effective November 3, 2025 (90 FR 42517).
FAA test documents
What the FAA publishes about the knowledge test: the standards questions are written to, the figure booklet you are handed, and notices about changes.
- FAA-S-ACS-10B, Remote Pilot Small Unmanned Aircraft Systems Airman Certification Standards April 2021, effective April 6, 2021 Still the current ACS for this test when we checked it.
- FAA-CT-8080-2H, Airman Knowledge Testing Supplement for Sport Pilot, Recreational Pilot, Remote Pilot, and Private Pilot 2018 The figure booklet the test center gives you. Large file.
- Unmanned Aircraft General (UAG) Sample Questions August 10, 2021 46 questions. The FAA publishes no answer key.
- Changes to Testing for a Remote Pilot Certificate with a Small Aircraft Rating Issued April 5, 2021
- Airman Testing Frequently Asked Questions Updated June 1, 2026
- Airman Testing Community Advisory (ATCA) August 2026 Announces image-based UAG questions from current sectional charts starting October 26, 2026.
FAA guidance and handbooks
Explanatory material the FAA publishes, most of it listed as references for the test. AC 00-45H is not on that list; we use it to decode weather reports.
- AC 107-2A, Small Unmanned Aircraft System (Small UAS) February 1, 2021, editorial update May 26, 2022 The version we cite. We keep two earlier printings for history only.
- FAA-G-8082-22, Remote Pilot Small Unmanned Aircraft Systems Study Guide August 2016 Still useful for weather, charts and performance. Out of date on regulations; see below.
- FAA-H-8083-25C, Pilot's Handbook of Aeronautical Knowledge 25C, 2023 minor revision
- AC 00-45H, Aviation Weather Services Change 2, March 6, 2019 (includes Change 1) Published with the National Weather Service. Our source for METAR and TAF codes the handbook does not explain, such as calm wind, sea-level pressure and wind shear groups.
- Aeronautical Chart Users' Guide Effective July 9, 2026 The old faa.gov link for this guide now returns an error; this is the current one.
FAA web pages
Pages the FAA updates more often than its PDFs. We note the "last updated" date each one showed.
- Become a Certificated Remote Pilot Last updated June 9, 2026
- Part 107 Airspace Authorizations Last updated March 26, 2025
- UAS Data Exchange (LAANC) Last updated August 25, 2026
Testing vendor
PSI runs FAA knowledge testing. Its bulletin is the only non-government document we use, and we cite it for facts about test delivery only.
- PSI UAG Applicant Information Bulletin Effective September 29, 2025 Question count, time, passing score, current topic weights, ID and what to bring. Linked from the FAA August 2026 advisory.
- PSI FAA testing portal Checked September 13, 2026 Where you register, schedule and pay.
Superseded in older FAA material
Some FAA documents are still online but no longer match the rules. Where they conflict with a current regulation, the current regulation wins. These are the conflicts we found, and how we handle each one.
-
Night flight
Night flight under Part 107 used to require a waiver. Since the 2021 rule change it doesn't: pass the test (or complete training) after April 6, 2021 and use anti-collision lighting visible for 3 statute miles. Night waivers issued before April 21, 2021 stopped being usable after May 17, 2021. The 2016 Study Guide doesn't cover night operation at all.
-
The recurrent test
The Unmanned Aircraft Recurrent (UGR) knowledge test ended on April 6, 2021. Free online recurrent training replaced it. Recurrent training completed before that date does not give you night privileges.
-
Operations over people and Remote ID
Both topics were added to the test on April 6, 2021, with questions written from the rules themselves. The 2016 Study Guide covers neither, so study them from the current regulations.
-
Study Guide references
The 2016 Study Guide tells you to know AC 107-2. That circular was cancelled and replaced by AC 107-2A, which is what we cite.
-
The falsification rule
The ACS and AC 107-2A both point to §107.5 for falsification. Since November 3, 2025, §107.5 is reserved, and the rule now lives in 14 CFR 3.403 and 3.405.
-
Accident reporting wording
AC 107-2A says to report "within 10 days" and describes damage "greater than $500." The current §107.9 says no later than 10 calendar days, and excludes damage when repair costs $500 or less, or, for a total loss, when fair market value is $500 or less.
-
Topic weights
The April 2021 ACS gives percentage ranges for each test area (for example, Regulations 15 to 25%). PSI's September 2025 bulletin gives different single figures (Regulations 48%). We treat the ACS as the authority for content and the PSI bulletin for how the test is weighted today.
-
Figures on the test
The FAA-CT-8080-2H supplement, dated 2018, is still handed out. From October 26, 2026 the test adds images from current sectional charts that are not in it, so chart symbols should be learned from the current Chart Users' Guide, not only the supplement's legend.
-
Dead testing-matrix link
The testing-matrix PDF linked from the sample questions and the ACS returned a "not found" error when we checked. The replacement page offered no downloadable matrix, so we don't use it as a source.
-
When your test shows up in IACRA
AC 107-2A says test reports upload to IACRA immediately. The FAA's current web page says it may take up to 48 hours. We go with the web page.
-
Handbook edition
The 2021 testing notice cites the Pilot's Handbook of Aeronautical Knowledge, edition 25B. The current edition is 25C, a minor 2023 revision, and we cite its page numbers.
What we could not verify
The test fee. PSI sets and collects it. We found no FAA document that states the amount, and PSI's own site showed two different figures on the same day. So we don't quote a number: you'll see the price when you book at faa.psiexams.com.
