Aviation Theory Centre (ATC) is a Australian family owned business, that was developed to provide the aviation industry the highest quality training manuals and reference media for pilots – for all license levels and ratings.

The company has been in existence for more than twenty-five years, originating in Melbourne and relocating to Brisbane in 2009. Aviation Theory Centre researches, authors, illustrates, and edits all of its own material. Aviation Theory Centre has established a network of consultants who advise, critique and edit the drafts.

The Australian series of manuals complies with the CASA syllabus which in turn, is aligned with ICAO requirements. Aviation Theory Centre has also prepared books for publication in the US and UK through partner companies, ASA and Pooleys, respectively.

Average app with [mostly] great content (partly out of date)

Update to review below: Offline access and download speed problems fixed after they directed me to delete and reinstall the app. But marking-up in the app (highlighting, scribbling notes and answers on review questions) still causes the app to crash incessantly. Lots of IREX content is out of date, particularly since Part 91 came in, but even before that it still mostly reads pre-GNSS days re ground-based navaids vs RNP/GNSS/RNAV. ….. Original review: Content is excellent as ATC have been doing for decades, my first books over 20 years ago were invaluable to learn and understand all theory. This app needs to be thrown in the bin though. Downloading books for offline use took many attempts, seems you maybe have to leave the app running on the screen for it to download, and the speed is stupidly slow for some reason, I’m guessing because ATC’s servers are archaic? Then using them offline… certainly doesn’t work as smoothly as something should if it’s on my iPad. Sometimes sits there with a blurry screen like it’s trying to download. And it regularly crashes particularly when marking up with apple pen. Try harder ATC, this app really is a let down on your outstanding reputation.

No offline viewing

This is a review of the app, not the theory content of the titles.

The title I’ve purchased and downloaded has a “offline” tag over the corner of the thumbnail, but when opened each page loads as if it’s downloading while being viewed. To confirm this I disabled the internet connection and found I couldn’t view the book at all. This wouldn’t be a problem except that there are plenty of places I take my iPad for work where I’d like to study, but can’t use the ATC textbook I’ve paid for because there’s no internet available and the supposedly downloaded text doesn’t open.

Nothing wrong with content but app is hopeless

First off, no issue with the content. However the app won’t load textbook (checked internet connection) and I can’t download the textbook for offline use. Hopefully can get the bugs sorted quickly so I can access the textbooks to keep studying!
