Part 107 ACS Code Explainer

Turn ACS Codes Into a Study Plan

Your knowledge-test report won't say "you were weak on weather." It just lists codes like UA.III.C and leaves you to decode them. Those codes come straight from the FAA's UAS Airman Certification Standards — the exact blueprint your exam is built on. Search a code or a topic below, and you'll see what it means, why the FAA tests it, and exactly what to review before you walk back in.

Reading an ACS code

Once you can read a code, you can go straight to the topic behind it — no guessing. Every one follows the same pattern. Take UA.V.D.K2:

UAUnmanned Aircraft — the Part 107 standard (FAA-S-ACS-10).

VArea of Operation (I–V). V is Operations.

DTask within that area. V.D is Aeronautical Decision-Making.

K2A specific Knowledge element (K), Risk (R), or Skill (S) inside the task.

📘

This explainer is organized by Area and Task — the part of the code that pins down your topic — so you can head straight to what you need to study. Codes and wording follow the FAA UAS ACS; always confirm against the current published ACS for the exact element text.

Know where you're weak? Train it into a strength.

Inside the full training, the Topic Mastery Dashboard ties every question back to its ACS area — so you always know which topics still need work and can watch your weak spots turn into confidence. And you won't just memorize answers; you'll learn why they're right. One-time $39.99.
