Free Part 107 Study Materials, Ranked
Everything you need to pass Part 107 is free from the FAA: the study guide, ACS, sample questions and testing supplement, what each is for, and in what order.
You can pass the Part 107 test without paying for anything but the test itself. The FAA's own study materials FAQ points applicants to three free documents, and a handful of other free FAA publications fill in the rest. Here is what each one is, what it is good for, and the order that makes sense.
What are the three official FAA materials?
| Document | What it is | Use it for |
|---|---|---|
| Remote Pilot ACS | The list of every knowledge element the test can cover, with a code for each | A checklist: if an element is in the ACS, it can be on your test |
| Remote Pilot Study Guide | The FAA's study text for small UAS pilots | Your first read; short, and the weather and loading chapters are quoted on the test |
| UAG sample questions | 46 representative questions, each with an ACS code, no answer key | Seeing how the FAA phrases questions |
The sample questions come without answers. The sample questions post has every answer with the reason behind it.
$0
the cost of every FAA study document; the only required expense is the test fee
What other free FAA documents help?
- Testing supplement FAA-CT-8080-2H. The booklet of charts and figures you get at the test center. Practice with the same figures, not screenshots of other charts.
- Pilot's Handbook of Aeronautical Knowledge. The deep reference for weather, load factor and navigation. Read the chapters you need, not the whole book.
- AC 107-2A. The FAA's guidance on how Part 107 works in practice, from recurrent training to preflight checks.
- Aeronautical Information Manual. Airspace, traffic patterns, radio phraseology, lights and hazards.
- Aeronautical Chart User's Guide. The official key to every sectional chart symbol.
The FAA's sample question document also notes that PSI, the testing company, offers an online UAG practice test on its site.
In what order should you use them?
- Skim the ACS to see the five areas and how big each is.
- Read the Study Guide end to end. It is the shortest complete source.
- Work the sample questions with the testing supplement open, then check the answers.
- Fill gaps from the PHAK, AIM and Chart User's Guide only for the elements you miss.
- Take timed practice tests until your scores are stable well above passing.
The two-week study plan turns this into a day-by-day schedule.
Official documents tell you the rules. They do not tell you which ones you keep missing. That is what practice testing is for, and the full course post covers when paying for more structure is worth it.
Which free Clear107 tools fit in?
Clear107's free tools are built on the same FAA sources: a 20-question diagnostic, sourced flashcards for every number and rule, a METAR decoder with a Part 107 altitude check, and calculators for civil twilight, density altitude and load factor.
Study guide first, sample questions second, everything else only where you miss.
Visiting from another country? The FAA's rules for foreign pilots are in flying a drone in the US as a visitor.
