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.

The simplest way to schedule your airplanes, and the app your pilots use to fly them. AviPrep is one schedule for Part 61 flight schools, flying clubs, aircraft owners, instructors and students. Owners see every airplane and every hour on one screen. Instructors see their day. Students book open times and follow their training from first flight to checkride. And anyone on the schedule can run it by text message. TEXT IT. IT'S DONE. Text AviPrep the way you would text the front desk. "Block N12345 Saturday morning." "Who's flying Sunday?" "Put Dave in the 172 every Tuesday 4 to 6 through December." It checks the airplane and the instructor, writes back what it found, and changes nothing until you reply YES. Ask AviPrep works the same way inside the app. FOR SCHOOLS, CLUBS AND OWNERS One screen for your fleet: dual, solo, rental and maintenance in their own colors. Approve every pilot, set your rates, and keep them. Pilots book themselves, every flight is billed on the Hobbs time flown and paid out to you, and squawks and inspection countdowns live on the airplane. Invite your people with a link or a text code; they're on the schedule in a few replies, no download required. FOR INSTRUCTORS Your students, your schedule, your rate. Set recurring availability once and students book into it. Lesson briefs before each flight, AI recaps after, and a shared syllabus that tracks every lesson. Teach in aircraft from the owner network when you don't have your own, and get paid after every lesson. FOR STUDENTS Find a CFI near you by airport, price and focus, see their aircraft and availability, and book in a few taps. Follow one structured path to your checkride, see what each lesson costs before you book, and keep a training record that goes with you. ALSO IN THE APP • Messaging with your instructor or students, with the lesson agenda in the thread • A training dashboard: upcoming lessons, recent activity, next steps • Weekly training streaks to keep momentum between lessons • Push notifications for bookings, schedule changes, messages and reminders • Weather at your field on the day's schedule Your records are stored privately and securely. Your students, your instructors, your rates and your data stay yours. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy: https://www.aviprep.net/privacy
