## What is Groundwork?

Groundwork prepares you for the FAA Part 107 knowledge test — the Unmanned Aircraft General exam for a Remote Pilot Certificate with a small UAS rating.

It is built on one idea: you should be able to check us.

EVERY ANSWER SHOWS ITS SOURCE
Every question in Groundwork cites the exact FAA paragraph that settles it — and prints the passage, word for word, under the answer. 14 CFR § 107.51(b), not "trust us."

That matters more than it sounds. Prep apps in this category are widely reported to ship wrong answers, and stale ones: rules changed in 2021 for night operations, operations over people and Remote ID, and material written before then is still circulating. Groundwork shows you the edition date of every document it draws on, so you can see for yourself whether it is current.

BUILT ON THE FAA'S OWN BLUEPRINT
The FAA publishes exactly what the test may ask about: FAA-S-ACS-10B, the Airman Certification Standards, with five Areas of Operation, 17 Tasks and 176 knowledge elements. Groundwork is organised by that document rather than by an invented chapter list, so "what is left to learn" has a checkable answer.

Study any Area of Operation, drill a single Task, and see which knowledge elements you still miss.

MOCK EXAMS THAT MEAN SOMETHING
60 questions. Two hours. 70% to pass — the FAA's own numbers.

Questions are apportioned across the five Areas in the FAA's published weighting, so a score here means what a real score means. A mock exam built to the wrong proportions gives you a readiness number that misleads, and that is the failure this app exists to avoid.

WHAT YOU GET
• 137 questions, every one cited to 14 CFR part 107, part 89, part 48, the ACS, the Chart User's Guide or the Pilot's Handbook
• 22 of the FAA's own published sample questions, marked as such
• The source passage quoted under every answer
• Full ACS browser: 5 areas, 17 tasks, 176 knowledge elements
• Unlimited mock exams at the real blueprint
• Readiness tracked per ACS knowledge element, so you drill what you are weak at
• Works completely offline

NO ACCOUNT. NOTHING UPLOADED.
There is no sign-up, no analytics, no trackers, and no network calls. Your answers and study history live in a single file on your device, and deleting the app deletes them. The privacy label says Data Not Collected because it is true.

ONE PAYMENT
$29.99 once unlocks everything, permanently. Not a subscription. Nothing auto-renews. It restores free on your other devices.

The FAA charges $175 to sit the knowledge test, and again if you fail it.

Try it first: the study browser, the source citations and 25 practice questions are free forever, and one scored mock exam. Check our accuracy against the FAA documents before you pay a cent.

SOURCES
• 14 CFR parts 107, 89 and 48 (current e-CFR)
• FAA-S-ACS-10B — Airman Certification Standards
• FAA-H-8083-25C — Pilot's Handbook of Aeronautical Knowledge
• FAA-G-8082-22 — Remote Pilot Study Guide
• FAA Aeronautical Chart User's Guide
• AC 107-2A — Small Unmanned Aircraft Systems

All are works of the U.S. Government and are not subject to copyright.

Groundwork is study material. It is not affiliated with or endorsed by the FAA, and passing a mock exam here does not guarantee a pass on the real test. Always confirm current requirements against the source documents.
