← Checkride prep

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.

FAA handbooks

The FAA's own textbooks. Free PDFs, written by the agency that writes the test and the ACS.

Regulations and the AIM

The rules, and the official guide to flying in the system. Always use the current version.

  • 14 CFR (eCFR): Parts 1, 43, 61, 67, 68, 91

    The Federal Aviation Regulations, always the current text, free from the government.

    Best for: Checking exactly what a rule says, and what changed. Printed FAR/AIM books go out of date.

    • Bookmark Part 61 (certification) and Part 91 (operating rules).
    • Read the whole section, not just the paragraph you remember; the exceptions matter.
    • Use the 'timeline' view to see recent changes.
  • Aeronautical Information Manual (AIM)

    Current: Effective: 7/9/2026 Change: Change 3

    The official guide to flight information and ATC procedures: airspace, radio work, airport operations, weather services, emergencies and medical facts.

    Best for: How to actually operate in the system, beyond what the regulations say.

    • Read chapter 4 (ATC) before you fly into towered airports.
    • Read chapter 8 (medical facts) before your first long or high flight.
    • It changes twice a year; check the effective date and the change summary.

Standards and the knowledge test

Exactly what your checkride covers, and the figures used on the written test.

Advisory circulars

The FAA's guidance on how to comply with the rules and fly safely. Short, practical, and free, and most pilots never read them.

Charts, airports and NOTAMs

What's on the chart, what's at the airport, and what changed today.

Safety programs

Free courses and articles that keep you learning after the checkride.

  • FAASafety.gov and the WINGS program

    Free online courses, seminars and the WINGS proficiency program from the FAA Safety Team.

    Best for: Keeping learning after the checkride; a WINGS phase can also satisfy a flight review.

    • Create a free account and browse courses by topic.
    • Pick a course on your weakest area each month.
  • AOPA Air Safety Institute

    Free safety courses, accident case studies and videos.

    Best for: Learning from real accidents, so you don't repeat them.

    • Watch the accident case studies for the kind of flying you do.
