We believe (and scientific study validates) that the interactive activity of test preparation, when combined with the sort of detailed supplementary and explanatory material that we offer, is an excellent way to thoroughly learn and internalize key aviation information.
We are test prep specialists and the experience of thousands upon thousands of pilots proves that our method works. We do not use test prep as a "hook", as some of our advertising-based competitors do, to sell you expensive but ineffective passive video-based courses and similar products that do little besides waste your time and drain your wallet.
Use our material and study hard - not just the questions and answers, but the reasoning and explanations too, and be on your way, in a highly time and cost efficient way, to knowledge test and aviation success!
Choose the Flight Engineer test you need.
The Flight Engineer test bank covers the reciprocating, turboprop, and turbojet entries shown below. Select your exact test inside the app.
FEX − Flight Engineer Turbojet/Basic  | FEJ − Flight Engineer Turbojet (added rating) | ||||
| FET − Flight Engineer Turboprop/Basic | FEP − Flight Engineer Turboprop (added rating) | ||||
| FEN − Flight Engineer Reciprocating Engine/Basic | FER − Flight Engineer Reciprocating Engine (added rating) |
Make your study time count.
Review aircraft systems, performance, and operating knowledge at your own pace. Select the applicable Flight Engineer test so your study sessions concentrate on the material relevant to that test.
- Actual and highly realistic FAA questions that closely reflect exam content, with explanations that prepare you for familiar questions and new variations. How our question banks are maintained.
- Required charts and figures included so the relevant reference material is available while you study.
- Flexible review and unlimited practice tests to help you concentrate on weak subjects and check your progress.
- Study on your schedule, with no need to wait for a class or for materials to arrive in the mail.
Choose a study screen to preview it; select the image to open it at full size. Appearance and available features vary by platform and app version.

Knowledge testing and systems review
Use GroundSchool to prepare for a required Flight Engineer knowledge test or to review the associated aircraft-systems material. Confirm any certificate, training-program, or employer requirement before selecting a test.
Different Flight Engineer tests have different authorization requirements. Check the current FAA testing matrix and §63.35 with your training provider.
Flight Engineer guidance from the Dauntless helpdesk
- FEX/FEJ - Flight Engineer Turbojet Basic/Added Rating
- FET/FEP - Flight Engineer Turboprop Basic/Added Rating
- FEN/FER - Flight Engineer Reciprocating Basic/Added Rating
- Relatively few people these days take the FE exams. As such, the FAA does not update them often and some of the questions on them are quite old and often out of date. It is what it is. It still can be interesting and useful for a surprisingly wide range of aviation activities and all else being equal, no matter what you fly you'll be a better informed pilot if you study for and pass an FE test.
- Moreover, we and other test prep providers get relatively little feedback on the FE tests these days. From the users who do take the test, we tend to get score feedback ("I got a 96%!", "I got a 90%!", etc.) but not specific question feedback.
- The tests are not easy, but are manageable by any reasonably qualified person who puts in the time and effort to study. For the Turbojet tests, which most people take, it will take as a VERY rough estimate 20-40 hours of study using our app.
- Some airlines and companies view your taking and passing the FE test - normally the turbojet one in such cases - as helpful to your application for a pilot job even if the aircraft/company you might fly with no longer has flight engineers.
- Some non-US countries continue to use the FAA Flight Engineer tests for validation of their Flight Engineers. Our prep will almost certainly be fine for you if this applies to your country.
- That said, we absolutely have the best FE test prep in the business. We have the most detailed explanations and by far the best overall user experience. While we don't have a lot of FE users these days, feedback has overall been excellent from those who have used our preps to pass.
- Obviously, if you're going to be taking a very rare FE test, like a reciprocating engine FE test in 2026, we ask for your understanding that our app is necessarily a 'best effort' sort of affair. While the FAA has carried through a lot of the guidance material into relatively new versions of their FE handbooks, some of the nuance has been lost and at times there is a bit of a disconnect between the handbooks and the questions. We're not trying to put you off - our prep is still very much the best out there for this and there's no reason that we know of that you shouldn't pass if you put the time in to study. We're just trying to align your expectations with the reality that some of these tests are taken by a few handful or fewer people per year at most in some cases, so you can't expect the FAA test bank to be as polished or current as it is for, say, the Private Pilot Airplane test.
- It is highly recommended that you supplement your study using our FE test prep app with reading FAA handbooks which you can download for free from the FAA website. Look at the references of questions in our test prep to see what handbooks the information comes from. A combination of our app and reading of official, current FAA handbooks is absolutely the best, proven way to prepare for your FE test. That also said, you can certainly pass your FE test if you only use our app to study.
Current learning material. Long-term value.
Keep your preparation up to date.
Our editorial team regularly maintains the questions, explanations, and supporting learning material. Use the content-update option in your app before starting a new round of preparation and periodically as you study.
Free lifetime content updates are included for your purchased test bank, subject to the applicable product and platform terms. Read about question-bank updates.
More about content updates
With our FAA Written Test Prep app, you don't have to worry about having an out of date version. Our authors work to update the data as FAA question pools change. Groundschool has a built-in self-update feature that connects to our servers and makes sure that you have the latest and greatest versions of the app and data soon after they becomes available.
Additionally, the self-update can be used to install new test data (such as Instrument Rating on top of Private Pilot) so you can have it when and where you need it.

Excellent app for a fraction of [competitor's] price! And this time I actually learned the material instead of cramming for a test!! Probably spent about 20-30 hours studying in a 2 week period and scored a 99 on the FEX and was able to relax in comfort of my own home during my self paced study plan.
... got a 98% on ATP and 100% on FEX using your app ...
I studied for four nights and got a 100% .. thanks!

More GroundSchool user feedback
Additional genuine feedback about GroundSchool, with the original attribution and the training context described by each user.
I believe that your product is ABSOLUTELY EXCELLENT . I has been a joy to work with. All the more so due to your very prompt response to my questions..
I was about to order the [ competitor's product ] when I noticed your product. Because it was downloadable, I could start practicing right away. And, the price was right. I'm a 64 year old 1000 hour private pilot with instrument rating who suddenly decided to get my Commercial and CFII as a retirement vocation. I don’t learn as fast as I did 40 years ago. GroundSchool has been a great learning and practicing tool.
I will tell you that I think your app is a wonderful product and I have personally recommended it to many students at [FBO] ground school classes... in fact as a result of using your program, my wife blew by the other students in her class! This has been a tremendous confidence builder for her as she was somewhat intimidated by the other students (all male) Kind of fun to watch their faces when she completes a multiple chapter review in 1/4 of the time they took. Now, they make comments during the correction like..." well I had answer A but [wife's name] has answer B and I'm sure she has the right answer " We're having a great time with your app even I use it to keep myself fresh... Thanks!
