This app is a collection of Glossaries found in FAA publications for pilots. It includes terms and acronyms from seven FAA books including: Handbook of Aeronautical Knowledge, Airplane Flying Handbook, Instrument Flying Handbook, and Aviation Weather. It also includes the acronyms from the AIM, the complete Pilot/Controller Glossary, ATC Glossary, and definitions from the FARs.

The terms can be browsed by book or by category—Private, Instrument, Advanced, Weather, Aircraft, Human Factors, Non-Airplane, and CFI. A quiz section lets you test your knowledge of random terms.

When taking the quiz, words can be marked as “Favorite” when they are on the screen. If you didn’t know the definition, you might want to mark the word as “Favorite” and then later review just the ones that are marked. Words can also be marked as Ignore when they are on the screen. Words marked as “Ignore” will not be displayed.
