Store description excerpt
Preparation for all three FAA Aviation Mechanic knowledge tests — General, Airframe and Powerplant — built directly on the standard the regulation actually cites. THE GENERAL TEST IS FREE. ALL OF IT. Not a sampler and not a trial. Every General lesson, every General question, and the full-length timed General form, free, with no account and no network. General is the highest-volume of the three tests and the one most candidates sit first. You can find out whether this app is any good before you are asked for money. BUILT ON FAA-S-ACS-1 14 CFR 65.23 incorporates the Aviation Mechanic Airman Certification Standards by reference, which makes it both the syllabus and the law. This app covers all 495 knowledge elements across the 40 subject areas of the three tests, and every question names the element it was written from. When you want to check a claim, you are one code away from the source rather than trusting a study guide. THREE OPTIONS, LIKE THE REAL TEST FAA mechanic questions give you three choices, not four. Practising on four-option items trains elimination habits that do not transfer. Every multiple-choice item here has three options. FULL-LENGTH TIMED FORMS 60 questions for General, 100 each for Airframe and Powerplant, two hours apiece, 70 percent to pass — the real shape of each sitting. Forms are drawn across every ACS subject area in that test, in proportion to the knowledge elements each one carries, and you get a per-subject breakdown at the end so you know where the marks went. WORKED SOLUTIONS, NOT BARE ANSWERS Compression ratio, piston displacement, brake horsepower, weight and balance, electrical load, blade angle. Every calculation shows its steps with the units carried through, so when you get one wrong you can see which line you lost it on instead of guessing. THE CALCULATORS ARE FREE. FOREVER. Weight and balance, Ohm's law, engine math, unit conversions. They stay free whether you buy anything or not, because a mechanic uses these numbers on shift for a whole career and a reference tool you have to subscribe to is a reference tool you stop opening. ALSO INCLUDED Flashcards and scenario-based activities. Spaced repetition that surfaces what you are actually forgetting. Progress tracking per subject area, bookmarks, and personal notes. Everything is on the device and works with no signal, because hangars are steel buildings. FREE, AND WHAT THE UNLOCK ADDS Free: the entire General test — 35 lessons, its full question bank and its timed form — plus every calculator and a sample of Airframe and Powerplant questions. The one-time unlock opens the Airframe and Powerplant banks, their timed forms, spaced repetition across them, and weak-area analytics. One payment, no subscription, no account. WHY THIS EXISTS Powerplant passes at 63 percent, the lowest rate of any knowledge test the FAA administers, and Airframe and General are not far behind. Failing costs a test fee and a 30-day wait. This app is built for the reta
