Spend less time studying and more time flying! This is the FAA Aviation Mechanic - Powerplant version of GroundSchool, our FAA knowledge (written) test preparation featuring up-to-date questions, free updates, and a question databank maintained by our professional team of mechanic instructors and examiners.

GroundSchool is fully compatible with FAA ACS (Airman Certification Standards) and our editorial team is working to keep it so as ACS continues to evolve.

Don't be fooled by imitators! Competing apps use only the limited set of questions that the FAA publicly releases via its website - that is not enough to adequately prepare you for your test! Our GroundSchool app, on the other hand, features a much more comprehensive database (typically about 2-4 times the size of the demo FAA public one) of actual and current FAA questions that you likely can and will be asked on the actual test! This along with our detailed, professional explanations and easy to use interface are major reasons why pilots have come to trust GroundSchool.

Study actual, up-to-date FAA questions and then ACE your FAA Aviation Mechanic - Powerplant written test the easy way with GroundSchool FAA Knowledge Test Preparation software by Dauntless Aviation, the trusted leader in FAA written test preparation.


* Actual FAA Questions Current and Valid for Right Now. As soon as you install the software, use the 'update' feature and the software will connect to our servers, grab the latest questions, images, figures, and explanation content, and you'll be good to go.
* Question bank maintained by our experienced editorial team.
* All Charts and Figures Included
* Several flexible study modes - fits the way you want to study!
* Compatible with all FAA and private "ground school" mechanic classroom-based courses

With Dauntless Aviation's GroundSchool, you don't need to worry:

* Our material is UP TO DATE. No matter what date is listed here in regarding the 'Release date', this date refers to the program itself only. Once you get the program on your device, use the built-in update feature and it will connect to our servers and download the latest and greatest version of the test prep content that we have available. To learn more about this, please visit our website.
* Furthermore, you are welcome to update the material as often as you like. This means that even if you don't take your test soon, when do you, GroundSchool will be ready for you. Compare this to books or DVDs (which are going out of date from the moment they are printed).
* Tens of thousands of people have used our products to prepare for their FAA knowledge tests. Ours is a system that works.

This is the Aviation Mechanic - Powerplant version of the software only. Most serious mechanic students will want to purchase all three - General, Airframe, and Powerplant versions of this software to help their study. These must be purchased separately via this Appstore.

Good luck on your test!

Highly recommended!

This study prep software is fantastic! I recently completed my Airframe and Powerplant license in November and this application was a critical part of my success. I used the Powerplant app to study in my spare time and take practice exam after practice exam until I felt ready for the real thing. The explanations are detailed and accurate, and I particularly liked the ability to focus on just those items I missed to reinforce my weak areas. I highly recommend this application to anyone studying for the Powerplant exam.

Ergonomics change with update

I have to tell you that this app is amazing! It works well and the questions are updated regularly. It is by far the best A&P test prep around.
I do have a concern for the dev. In that the new update has moved the arrows to change questions so far into the bottom corners of the screen that it is impossible to hold the phone with one hand and comfortably navigate the questions. I find myself with constantly overstretched fingers or switching hands to change questions every 5 to 10 seconds.

Expensive for occasional wrong answer

App is waaaay too expensive but looked trustworthy. Unfortunately, I'm at a schoolhouse, in the middle of taking my tests and have found MORE THAN ONE ANSWER incorrect and rather than get better info, the developers act like you are an idiot when you report a wrong answer. Major unprofessional for a ridiculous price. Most questions/answers are correct, but after reporting incorrect ones to "know-it-alls" who'd rather tell you how ignorant you are than address the discrepancy (the test is right even if its wrong after all...) I'd spend my money on one of the MANY cheaper apps that do the exact same thing and likely better.
