FAA Aeronautical Chart Users Guide
The FAA is discontinuing production of the C.U.G. in 2025 and will eventually remove it from their FAA website. This is a mirror of that document for posterity due to the wealth of knowledge it contains.

The P-8740-13 document in an easily download and portable format disappeared years ago, so this is a recreation of that document using the text on the FAA Safety website.
Currently a work in progress, but this guide matches ACS codes to FAA provided content and regulations to guide students and instructors for check ride preparation.
