Part107Prep Methodology

Sources of truth

Every question on Part107Prep traces back to one of the following FAA public domain documents. The source citation is shown on every question's explanation. If a citation is missing or you cannot reconcile a question with its cited source, that is a bug and we want to hear about it.

1. 14 CFR Part 107. The federal regulation that defines small unmanned aircraft operations. Authoritative for altitude limits, speed limits, visibility minimums, registration, certificate eligibility, accident reporting, and waiver categories.
2. FAA Remote Pilot Study Guide (FAA-G-8082-22). The FAA's official preparation document for the Unmanned Aircraft General (UAG) knowledge test.
3. Airman Certification Standards for Remote Pilot (UAS ACS). The task by task list of what the exam can ask. Every question we write is mapped to at least one ACS task code.
4. FAA Aeronautical Information Manual (AIM). Used for airspace classification, communications procedures, and chart symbology that feed into Part 107 exam content.
5. FAA Official UAG Sample Questions. The public domain sample bank the FAA publishes for candidates. We include the text-only items from this bank verbatim and label them as verbatim FAA questions.

We do not copy questions from commercial test prep products. Every non-verbatim question in our bank is drafted directly from the FAA documents above, not from another prep product, a forum post, or anyone's memory of a real exam item. See How we use AI below for the drafting and review workflow.

How a question gets into the bank

Each question goes through the same path before it appears live on the site.

1. Source-anchored draft. A question starts with a citation from one of the FAA documents above. We write the question stem from the regulation or study guide text, not from another prep product, not from forum posts, and not from anyone's memory of a real exam item.
2. Three answer choices, FAA style. The real Part 107 test uses three answer choices per question (A, B, C). We follow that format. Our distractors are written to mirror the precision errors a test-taker makes when they know the concept but not the exact rule, not random plausible-sounding wrong answers.
3. Plain English explanation. Every correct answer is paired with an explanation that names the originating rule or document and explains why the correct choice is correct.
4. Watch Out (trap) note. Most questions carry a short note on why the most common wrong choice feels tempting. The Part 107 test rewards precision, and close-but-wrong answers are the kind that catch test-takers who know the concept but not the exact rule. We surface those patterns instead of hiding them.
5. Pro Tip. A short memory aid or real world reframe that connects the test answer to operational judgment. The goal is that a Part 107 pilot understands the material, not just the letter.
6. Verification timestamp. Each question carries a verified date showing the last time an editor confirmed the answer and citation against the live FAA source.
7. Difficulty tag. Each question is tagged easy, medium, or hard (see Difficulty philosophy below).
8. Domain assignment. Each question is assigned to one of the five FAA exam domains so the bank matches the ACS test blueprint shape.

Difficulty philosophy

Part107Prep is a drilling tool. Our goal is that a candidate who can answer our medium tier questions reliably is, by definition, exam-ready. We deliberately do not chase a hard-question count just to look rigorous.

The bank targets roughly the following mix:

If a topic does not have a credible hard question we can write honestly from FAA source material, we leave it at medium. We will not pad the hard tier with arbitrarily difficult or trick questions to hit a number.

Editorial rules

These are the rules we follow on every question, explanation, and article.

• Authorship anchored to source, not credentials. Articles and questions are attributed to Part107Prep, the site itself, rather than to a named author. The authority of the content comes from the FAA source material it is built from, not from any individual writer's credentials. We do not use bylines like "by a Part 107 certificated pilot."
• Complementary, not adversarial, voice toward other prep products. Part107Prep is the drill layer that pairs with a structured course. We will not disparage other prep products, even ones we link to as affiliates. If we recommend a course, we recommend it on its merits.
• FAA transparency language. When we describe our sourcing we use the verbatim phrase "derived from FAA public domain materials" and we cite the specific document. Quiz surfaces carry an "educational purposes only, verify with FAA" disclaimer.
• Free practice, no email required. Quizzes are free with no email required and no signup. Downloads such as PDFs or compiled study guides may ask for an email; the practice itself will not.

How we use AI

Part107Prep is drafted with AI assistance and reviewed by hand against the FAA source materials listed in Sources of truth before publication. We use AI the way a working writer uses a research assistant: it speeds up the labor, it does not replace the judgment.

What AI does:

• Produces first drafts and rephrasing options from the source documents.
• Surfaces likely misreadings and ambiguous wording the FAA might use as distractors.
• Helps maintain consistent voice and structure across articles and explanations.

What AI does not do:

• Select which FAA documents are authoritative.
• Assign difficulty tiers or domain mapping.
• Push content live without a human review pass against the cited source.

Every claim on every page is reconciled with the cited FAA document before going live. If you see a sentence that reads as off, or a claim you cannot trace to a cited source, tell us through the feedback form on any quiz results page and we will fix it.

Bank composition

The bank currently contains 251 questions across the five FAA exam domains, weighted to mirror the ACS blueprint.

Of the 251 questions, 33 are drawn verbatim from the FAA UAG sample bank and 218 are original questions written from FAA source material for Part107Prep. The bank grows on a rolling cadence; see the public changelog for dated additions.

Gaps we are honest about

The Part 107 exam includes some content we do not yet cover. We name the gaps so candidates can plan their study.

• Chart and figure questions. Roughly 20 to 25% of the live exam references the FAA-CT-8080-2H figure supplement (reading sectional charts, identifying airspace boundaries by coordinate, locating obstructions). These require chart images we have not yet built. SkyVector and the FAA figure supplement are the right tools for that practice today.
• Full timed 60-question simulation. The Quick Quiz and per-domain modes do not yet enforce the live exam's 60-question, 120-minute timing.
• Cross-session score tracking. Scores reset when you close the browser. Score history and weak area tracking over time are planned.

How we handle corrections

The feedback form on the results page is the front door for question reports. Every report is read and triaged. When a report identifies a wrong answer or an outdated citation, the fix lands within the same week and is recorded in the public changelog with a dated entry. We do not silently edit answers; the changelog shows what changed and when.

What this site is not

Part107Prep is not affiliated with the FAA. We do not issue certificates. We cannot guarantee a pass. Regulations change, and the authoritative source for any current rule is the FAA itself. Always verify current rules with the FAA before operating.
