Read full descriptionHide full description
Pass the Private Pilot written test and walk into the checkride oral ready. PPL Ace turns the FAA knowledge areas into a daily plan you can actually keep. STUDY SMARTER, NOT LONGER • 1,135 questions across all 16 knowledge areas: aerodynamics, weather, regulations, airspace, navigation, performance, weight and balance, systems, instruments, airport operations, radio, emergencies, night, cross-country, human factors, aeromedical. • Every question has a full explanation and the CFR, AIM or FAA handbook reference behind it. • Answers are shuffled every time, so you learn the material, not the letter. • Missed questions come back on a spaced-repetition schedule until you own them. A PLAN BUILT AROUND YOUR TEST DATE • Set your test date and get a day-by-day calendar: weak topics get more days, a mock exam every week, a full 60-question mock before the test, and a rest day after. • Today's Plan on the Home screen tells you exactly what to do. Completion is tracked from your real sessions, no manual check-offs. • A readiness score tells you when you are actually ready. MOCK EXAMS LIKE THE REAL THING • 20, 40 or 60 questions, timed at the FAA's pace, 70% to pass. • Results broken down by topic with ACS codes, just like the official knowledge test report, so you know exactly what to brief with your instructor. CHECKRIDE ORAL PREP • 70 examiner-style questions organized by ACS task, from pilot qualifications to emergency operations. • Answer out loud, reveal the key points the examiner is listening for, grade yourself, and see the follow-up they are likely to ask. • Flashcards for rapid-fire review. Swipe right if you knew it, left to see it again. • Examiner Log: write down what your instructor or examiner actually asked you, then drill those questions like any other. TOOLS FOR TEST WEEK • Cram sheets built from the explanations of everything you missed, per topic or across the board. Export to PDF. • A pre-test checklist for the knowledge test, the checkride and the final 48 hours: endorsements, IACRA, what to bring. • A weekly recap with a shareable card showing your scores, streak and the topics that moved. STAY CONSISTENT • Free Question of the Day with its own streak. • Study streaks, 16 achievements, and a daily plan that fits the time you have. • Home Screen and Lock Screen widgets with your streak, today's progress and the Question of the Day. • Daily reminders that name today's topic, and a nudge when a streak is at risk. • iCloud sync keeps everything in step across your devices. FREE AND PREMIUM Free: one quiz a day, the Question of the Day, the first oral prep task, bookmarks, review, cram sheets, and the study plan. Premium unlocks unlimited quizzes and mock exams, flashcards, every oral prep task and the mock oral, PDF export, and a weekly streak freeze. Monthly or one-time lifetime purchase. Questions are written to the Private Pilot Airplane ACS (FAA-S-ACS-6C) and current 14 CFR Parts 61 and 91. Found something wrong? Flag it from any question and it is fixed in the next update. Privacy: no account, no ads, no tracking. Your study data stays on your device and in your iCloud.
