Terms of use

What this site is

Part 107 Drills provides practice material — mock tests, question sets, explanations, an ACS code reference and guides — for people preparing for the FAA’s Unmanned Aircraft General knowledge test. Using the site means you accept these terms.

All of it is free: every question, every explanation, every ACS code lookup, unlimited practice by area and unlimited full-length mock tests. There is no account, no subscription and nothing on sale.

Who we are not

Part 107 Drills is independent practice material. It is not affiliated with, endorsed by, or authorized by the Federal Aviation Administration, PSI Services LLC, or any knowledge testing centre. Every question here is original and none is taken from any actual FAA knowledge test. Regulatory text and FAA publications are works of the United States Government and are in the public domain; where this site states a rule, it cites the section it came from and the date that section was read.

We name the test and cite the regulations to describe what our material prepares you for and to show where our figures came from. That is the whole of the reference: we are not affiliated with the FAA or with PSI Services, we do not administer any knowledge test, we cannot register you for one, and nothing here is an official practice product of anyone.

Whose questions these are

Every question and explanation on this site was written for it. None is taken from an actual FAA knowledge test, and we have never had access to one. Anyone offering you the real items is either mistaken or breaking an agreement — and 14 CFR § 107.69 makes copying or removing a knowledge test grounds for a one-year prohibition on applying for any certificate.

Regulatory text, advisory circulars and FAA handbooks are works of the United States Government and are not subject to copyright under 17 U.S.C. § 105. Where we quote them — an ACS element, a definition, a limit — the quotation is theirs and the surrounding writing is ours. Our questions are provided for personal practice; please do not reproduce them in bulk or republish them as your own. Linking to any page here is welcome.

Accuracy, and its limits

Facts about the test and the regulations on this site carry the document they came from and the date that document was read. We would rather leave a fact out than guess at it — which is why no page here quotes a test fee, since the FAA does not publish one.

Even so: regulations are amended, and guidance is rewritten without announcement. Where our page and the current 14 CFR disagree, the regulation is right and this page is out of date. Do not treat anything here as a substitute for reading the rule that applies to your operation.

No guarantee of outcome

We do not promise that using this site will help you pass, and we publish no pass rate and no score prediction. A score here is a practice signal, not a forecast: the real test is written by the FAA, delivered by its testing vendor, and scored against a standard we do not administer.

Not operational or legal advice

Nothing here is advice about a flight you are planning, an authorization you need, or a waiver you are seeking. Whether a particular operation is lawful depends on facts we do not have. For an actual operation, read the regulation, and where it matters, ask the FAA or someone qualified in your jurisdiction — not a practice site.

Provided as-is

The site is provided as-is, without warranties of any kind. To the extent permitted by law, we are not liable for any loss arising from its use, and any liability we do have is limited to what you paid us.
