Study smart and pass. KnowTAM is flashcard, quiz, practice-exam, and oral-exam prep for your FAA knowledge tests and checkrides, with over 1,800 cards across every rating. Whether you're a student knocking out your first written, a pilot prepping for a checkride, or staying sharp for a flight review, KnowTAM gets you ready and keeps you ready. WHAT'S INSIDE • Flashcards with the answer, a CFI explanation of the "why," the regulation or handbook reference, and the exact FAA ACS code each card maps to, all written to the Airman Certification Standards. • "Refer to the figure" questions on real FAA images: sectionals, instrument and approach plates, airport signs and markings, and weather diagrams. • Multiple-choice quizzes by subject area that don't just mark you wrong; they highlight exactly why each wrong answer is wrong, with instant feedback scored against the 70% FAA passing mark. • Full-length practice exams built like the real thing: a short question with three lettered choices, timed, scored against the 70% passing mark, with Private exams drawn to the FAA's subject blueprint so the mix matches the real test. • A study plan paced to your test date: tell KnowTAM your rating and when your written is, and it sets each day's new cards and reviews, shows whether you're on track, and tells you when to take a practice exam. • Spaced repetition that brings back the cards you miss and spreads out the ones you know, so you reach "mastered" and stay there. • Checkride / oral-exam sets that drill the way a Designated Pilot Examiner actually asks. Also perfect before a flight review. STUDY ANYWHERE, ANYTIME KnowTAM works fully offline: no signal, no problem. Everything runs in airplane mode with no account required, so you can study whenever and wherever you are: at the hold-short line, on a long cross-country, or on the airline ride to your checkride. START FREE Start free with Private: the first three modules are on us. And the entire Aviation Weather track is free for everyone: the atmosphere, fronts, thunderstorms, icing, mountain weather, and reading the reports, all with FAA diagrams. Unlock the rest of Private, add Instrument, Commercial, or Multi-Engine, or grab the all-access bundle. Simple one-time purchases, never a subscription. RATINGS COVERED • Aviation Weather (free for everyone) • Private Pilot • Instrument Rating • Commercial Pilot • Multi-Engine (Vmc, the critical engine, single-engine performance) Original, ACS-aligned content, written and reviewed by a working CFI. No account needed: your progress stays on your device unless you choose to sync it with a free account. An app by Fly With Winston.
