Sheppard Air is considered to be the gold standard for FAA knowledge test preparation by most pilots and instructors, and their newly redesigned Flight Test X20 app brings some welcome new features and improvements.
The tried-and-tested Sheppard Air “study strategy” remains unchanged in this new app. What has changed, however, is the user experience while studying questions. The X20 app uses a new split-screen design, allowing you to simultaneously view the question/answer and the explanation or the relevant figure. I have found that this greatly improves studying efficiently, as you no longer have to click back and forth between the question, the figure, and the explanation to understand how to answer the question.
Also new to this app is the ability to study with the iPad in landscape orientation. This is ideal for larger iPads, as it maximizes the available screen real estate.
Having studied for knowledge tests using both the older Flight Test 5 and this new Flight Test X20 app, as well as other test prep books and software, I can confidently say that Sheppard Air’s X20 offers the best efficiency and value. It is without a doubt the best way to ace your next knowledge test.
