Sectional chart & airspace drill
Quick answer
What's the hardest part of the Part 107 knowledge test?
Candidates most often cite airspace classification and sectional-chart reading as the section they struggle with, since it asks you to recognize dozens of line styles, colors, and boundary shapes rather than just memorize a rule. This drill isolates that skill into its own free, repeatable tool instead of leaving it as one chapter inside a paid course.
What this drill covers
25 items across 4 categories, drawn from the FAA Aeronautical Chart User's Guide, 14 CFR Part 107, and the NOTAM (Notice to Air Missions) categories a Part 107 candidate needs to recognize.

How the drill works
Untimed drill
Unlimited repeats, an immediate explanation after every answer, and a "review due" prompt that resurfaces the symbols you have missed before, tracked with the same spaced-repetition scheduling (SM-2) the site's main practice bank uses. Nothing is timed or graded against you; it is built for repeat practice.
Timed exam simulation
Runs the full item set under a countdown set to the real knowledge test's own pace, about 2 minutes per question. No feedback until you submit, the same way the real computer-based test withholds it, so you can rehearse answering under time pressure rather than just recognizing the right choice with unlimited time to think.
Everything you answer stays in your browser's local storage. We receive only an anonymous, banded summary (which symbols get missed most across every visitor, never your individual answers), disclosed in full in our privacy policy.

Airspace classes
On a sectional chart: Solid thick blue boundary lines, one ring per altitude segment, each ring labeled with its floor and ceiling in hundreds of feet (e.g. "70/SFC" meaning floor at the surface, ceiling 7,000 feet MSL). What does this represent?
Answer: Class B airspace
The airspace around the nation's busiest airports, generally shaped like an upside-down wedding cake of stacked rings with different floor and ceiling altitudes tailored to that airport's traffic. A Part 107 remote pilot may not operate in Class B airspace without prior air traffic control authorization, obtained through LAANC (Low Altitude Authorization and Notification Capability) where available or a manual authorization request otherwise.
