FAA Unmanned Aircraft General (UAG)
Sixty questions, weighted the way the FAA weights them
Free Part 107 practice tests dealt in the proportions the FAA publishes, scored at 70%, and reported back as the ACS codes a real test report prints.

Questions written
ACS elements covered
Minutes on the clock
Every figure counted from the bank when the site was built, not claimed. Each question carries the ACS code it tests and the FAA document its facts came from.
Questions written: 293. ACS elements covered: 176/176. Minutes on the clock: 120.
Practise one area at a time
Untimed sets, with the explanation, the ACS code and the source document after every answer. The percentage beside each is what the FAA says that area is worth on the real test.
One bar per question on a 60-question test, in the bands Appendix 1 of the Airman Certification Standards publishes. Operations is 38.3% of it and Loading and performance is 8.3% — which is the argument against splitting your study time evenly.
Three things this site does that the category does not
- Reports ACS codes
- A real Airman Knowledge Test Report gives you codes, not questions — and that list is the whole diagnostic. Every mock here reports the same codes and resolves each one to the FAA’s own sentence.
- Reads the regulation, not the 2016 guide
- The study guide the FAA still links is dated August 2016 and predates the amendment that rewrote night operations and added operations over people. Every rule here is cited to the current CFR, with the date it was read.
- Weights the test as published
- The FAA publishes a percentage band per area. The mock deals to it, and the build fails if a number drifts outside the band — so it cannot quietly stop being a mock.
What UA.I.B.K21b means
It is an ACS code, and it is what you get back on your test report instead of the questions you got wrong. It decomposes: UA the unmanned aircraft standards, I the area of operation, B the task within it, K21b the knowledge element — which in this case is “Altitude limitations”.
Every question on this site carries the code it tests, so a practice run tells you the same thing the real report will. All 176 elements are listed with the FAA’s own wording.
Browse every ACS codeCoverage
176/176
ACS knowledge elements with at least one question behind them, out of the 176 in FAA-S-ACS-10B. The number is counted from the bank, not claimed — and it is printed here because the honest thing to publish about coverage is the gap as well as the total.
293 questions · 134 elements have only one
Every element is covered; not every element is covered deeply. 134 of the 176 have a single question behind them today, which means a run that lands on one of those will hand you the same question it handed you last time. Depth is what the bank grows next, and this number is how you will know it did.
Why this site exists
The study guide the FAA still links is dated August 2016.
Part 107 was rewritten in 2021 — night flying, operations over people, Remote ID. A great deal of the free material in this category was written from the older document and still teaches rules that no longer exist. Every fact here carries the document it came from and the day it was read.
What is actually on the testBefore you book the test
What changed in Part 107 in 2021
Amendment 107-8 rewrote night operations, added four categories of operations over people, and brought in Remote ID.
How the Part 107 test is scored
60 questions, 120 minutes, 70% to pass — which is 42 marks. What the Airman Knowledge Test Report gives back, and why it is a list of ACS codes.
The Part 107 operating limits
51, what each one actually means, and the structure exception.
Part 107 recurrent training
The recurrent knowledge test no longer exists. Recency is kept with a free online course — ALC-677, or ALC-515 for part 61 holders — every 24 months.
Flying at night under Part 107
No waiver needed since April 2021. What § 107.29 requires — updated knowledge and anti-collision lighting visible for 3 statute miles.
How to get a drone license
The FAA’s own seven steps to a Remote Pilot Certificate — FTN, testing centre, the exam, IACRA, TSA vetting, registration — and what each one costs.
293 practice questions, every one written for this site and every one carrying the FAA document its facts came from — so you can check any answer against the FAA's own text rather than take ours for it.
Sources
Every figure on this page comes from one of the documents below, with the day it was read and what the document says about its own currency. Regulations change by amendment — open the source if you need today's text.
- 14 CFR part 107 — Small Unmanned Aircraft Systems (eCFR) Read August 27, 2026· eCFR reports title 14 up to date as of 2026-08-25 The regulation itself. Every operating limit, category, eligibility rule and recency rule on this site comes from here rather than from a guide about it. Amendment 107-8 (86 FR 4381, 15 January 2021) is the one that rewrote night operations and added operations over human beings.
- FAA-S-ACS-10B — Remote Pilot – Small Unmanned Aircraft Systems Airman Certification Standards Read August 27, 2026· Material in FAA-S-ACS-10B is effective April 6, 2021 The shape of the test and the ACS codes. Appendix 1 publishes the 60-question length, the two-hour limit, the 70% passing score and the share of the test each area of operation gets. Appendix 3 publishes that a passing test report is valid for 24 calendar months.
- AC 107-2A — Small Unmanned Aircraft Systems (small UAS) Read August 27, 2026· Dated 2/1/21 FAA guidance written against the amended rule. Used for the things the regulation implies without spelling out — what civil twilight means in practice, what a scalable preflight inspection is, how maintenance recordkeeping is expected to work.
- FAA-G-8082-22 — Remote Pilot – Small Unmanned Aircraft Systems Study Guide Read September 5, 2026· August 2016 — predates Amendment 107-8 ⚠️ Good for the subject matter, not for the rules. Airspace classes, METAR and TAF decoding, density altitude, load factor, physiology, radio procedure and airport data are unchanged, and that is what this study guide is used for here. Its regulations chapter, its night rules and its silence on operations over people are all out of date — for those, go to the regulation.
- FAA — Become a Certificated Remote Pilot Read September 2, 2026· Page states “Last updated: Tuesday, June 9, 2026” The certification path itself, step by step and in the FAA’s own numbering, for both routes: the first-time applicant who sits the UAG test, and the existing part 61 holder who takes the free ALC-451 course instead. Also the current recurrent training courses by number — ALC-677 for any part 107 certificate holder, ALC-515 for one who also holds a part 61 certificate with a current flight review — which the page states are at no cost. Re-read in full on 2026-09-02 for the licence-process guide; the seven steps and the June 2026 date were unchanged.
