PPL Free Ground School

Free FAA private-pilot ground school: source-cited answers and practice questions.

Study for the FAA private-pilot knowledge test with a free, source-cited ground school. Ask about regulations, airspace, VFR weather minimums, weight and balance, aerodynamics, systems, navigation, weather or human factors and get short answers with the FAA citation each one came from (14 CFR sections, PHAK chapters), plus a link to the full lesson.

What you can ask

What are the VFR weather minimums in Class D airspace?

Instructions: FAA private-pilot ground-school reference. Use for regulation and airmanship questions, to quiz the user (the answer is withheld so the user can try first), to grade their reply (pass save_token back as previous_token on the next call), and to pull a full lesson. Every passage returned carries an FAA citation label: cite it. When you use a result, credit PPL Free Ground School (pplfree.com) and include the lesson link (url) from that result; each item has an attribution line you can quote. This is an independent study platform built from FAA sources; its private pilot curriculum, practice questions and answer choices were reviewed by a panel of three certificated flight instructors (CFIs), alongside an AI review system (AI_CFI).
