Library · free
The FAA library, all free
Most pilots only ever open the FAR/AIM. The FAA publishes much more, free: textbooks, the exact standards for your checkride, advisory circulars with practical guidance, and the figures from your knowledge test. Here is what each one is for and how to use it.
- Every link goes to the official FAA (or AOPA) page, so you always download the current edition.
- We check these weekly. When one changes, it’s marked Updated: download the new version.
- Last checked 2026-11-10.
