PowerPlant Prep is a phone-first study kit with original practice questions, flashcards and interactive diagrams. Every question is referenced to the FAA Powerplant Handbook.
Study in ten-minute gaps between shifts. Your progress stays on your device, and nothing needs an app store.
Large type and readable labels. Add it to your home screen like an app.
After the first visit, study on the flight line or in a hangar with no signal.
Every question cites a chapter and page in FAA-H-8083-32B. Corrections are logged in a public errata list.
Realistic cutaways of 20 engine systems that break down complex components. Tap a part to learn it, take the label quiz, and watch four of them animate.
385 one-question flashcards that bring back what you miss until it sticks.
100 questions, 2 hours, 70% to pass, scored by ACS area. The final mock uses questions you haven't seen.
The questions are original, not a copied test bank. They're written from public FAA material so you learn the concept, not a memorized letter.
Realistic cutaways of the engines and systems the test asks about, with every label checked against FAA-H-8083-32B. Key systems are animated, so you can watch the airflow, fuel and valves move. Tap any image in the app to zoom in.
