CheckPrep vs KnowTAM

Purpose-built for pilots who refuse to leave their checkride to chance. CheckPrep is a checkride oral prep app for the Private, Instrument, Commercial and Commercial Multi Add-On practical tests, built around the FAA Airman Certification Standards (ACS), the exact framework your DPE uses to evaluate you. This is not written test prep. This is oral prep. STUDY THE WAY YOUR DPE TESTS YOU Every question, answer and reference is organized by ACS Area of Operation and Task, the same structure your examiner follows. Every card maps to an ACS task, so every minute of study maps to your oral exam. THE FAA LIBRARY, FREE FOR EVERY USER Full FAR, AIM, Advisory Circulars, the ACS documents themselves, FAA letters of interpretation, InFOs and the FAA handbooks: PHAK, AFH, Instrument Flying, Instrument Procedures, Aviation Weather, Risk Management, Weight & Balance, Chart Users' Guide and the AMT handbooks. Tap a citation on a study card to open the exact paragraph, page or ACS element. Bookmark passages, search by keyword, read offline after download. AIM paragraphs also open on the FAA website, so you never have to wonder whether it is current. KNOW WHEN YOU'RE READY Mastery is tracked from 0 to 100% for every ACS task. Flash cards and multiple-choice quizzes are built from the same cards. Switch on the Needs Review filter to limit a session to the cards you still miss and leave the mastered ones out. When every task reads 100%, you know where you stand before the examiner does. DECODE REAL-WORLD WEATHER METAR, TAF and PIREP decoding practice with live data from aviationweather.gov. Included free. TRAIN YOUR EAR Departure (CRAFT) and approach (P-TAC) clearance trainers read the clearance aloud. You give the readback by voice. Beta, included with the Instrument guide.

READY FOR THE NEW INSTRUMENT QUESTIONS Since October 26, 2026, the FAA's Instrument test includes image-based questions built on current sectional, approach, and low-altitude en route charts. KnowTAM's Instrument deck has 24 cards on current FAA chart excerpts, so you practice reading them before test day. WHY PILOTS PICK KNOWTAM • Every card explains the "why," not just the answer, with the regulation or handbook reference and the exact FAA ACS code it covers. • Quizzes show why each wrong answer is wrong. • Real FAA figures: sectionals, instruments, approach plates, airport signs and markings, weather diagrams. • Timed practice exams built like the real test, with the FAA's time limits, scored against the 70% passing mark. Private exams follow the FAA subject blueprint. • A flight computer that works like the electronic one you take to the test, right beside every practice exam question. • Checkride and oral-exam sets that drill the way a Designated Pilot Examiner asks. Great before a flight review, too. A PLAN THAT GETS YOU THERE ON TIME Enter your rating and test date. KnowTAM 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 brings back what you miss and spaces out what you know. In the final week, your plan brings back anything you haven't seen lately. STUDY WITH YOUR INSTRUCTOR • Share your progress by private link: practice exam scores, readiness by area, your study plan, and the ACS codes from your test report. It keeps up as you study and stops working when you turn it off. • Send a practice exam to your instructor, with every question you missed. • Lesson sets: your instructor sends the cards for your next lesson, with notes, as a link or a QR code. STAY WITH IT • A Today card with a ring for the day's cards, your streak, and a real finish when you're done. • Home Screen and Lock Screen widgets: today's plan with a Start button, your streak, and Plan details on the large widget. • Optional reminders at the times you choose, only on days your plan isn't done yet, plus reminders the week of your test. KNOW WHEN YOU'RE READY • Readiness by area shows which subjects are ready, close, or need work, from your practice exams and cards. One tap quizzes the weak ones. • Practice sets for the cards you missed recently and the ones you saved. • After the test, tell the app how it went. Passed? Share your pass and move on to your next rating. Didn't pass? Add the ACS codes from your test report, typed or read from a photo, and practice exactly those.
