How we check our questions

Every Part 107 answer is decided by documents the FAA publishes. A practice question is only as good as its tie to one of them. Three things make that tie checkable, and this is how each one works here.

1. It cites a specific FAA document

Each of the 464 questions names the source its answer comes from: a section of 14 CFR, a page of AC 107-2A or the Pilot's Handbook, or a numbered figure in the testing supplement, FAA-CT-8080-2H. The build fails if a question has no citation.

2. It is checked against that document's text

The checking runs against a library of FAA source texts. It holds the CFR sections the bank cites, taken from eCFR with the date the text is current to, and the documents the exam draws on: the testing supplement, AC 107-2A, the Pilot's Handbook of Aeronautical Knowledge, the Risk Management Handbook, the Remote Pilot Study Guide, the Aeronautical Chart Users' Guide, the Airman Certification Standards, the Airman Testing Community Advisories, PSI's UAG bulletin, the FAA's sample questions, and the FAA's LAANC and UAS Facility Maps pages. Each document carries its edition line.

In October 2026 every question was reviewed against that library, and each verdict quotes the passage it rests on. A question the text did not support was corrected. The October corrections are counted, with examples, in The source decides. Where a question cites something the library does not hold, the review records that it could not be checked, and the question is listed by name.

The review is not a one-time event. A source audit runs on every change to the bank and lists any question whose content no longer matches its review. When the FAA amends a cited section after the date a question records, the audit lists that too, so the questions to read again are named rather than guessed.

A person has also read 364 of the 464 questions against the source. That is a different claim from the review above, and the two are recorded separately.

3. The source is visible

Under the explanation, Read the source opens what the question cites. For the 274 questions that cite a regulation, it shows the section text, copied byte for byte from a dated eCFR snapshot, with the paragraphs the citation names highlighted. For the 57 questions built on a testing-supplement figure, the question shows the FAA page itself. For other documents, the panel names the document and its edition, and the resource library links to the FAA's own copy.

What this does not claim

It does not claim the bank is free of errors. It claims an error can be found, by us or by a student, because the source is named and the text is there to read. When one is found, it is corrected against the source and the correction is dated.
