The definitive FAA reference for understanding how to read and interpret all aviation charts.

Aeronautical Chart User's Guide is the definitive learning aid, reference document, and guide to the wealth of information provided on FAA aeronautical charts and chart navigation publications. Aviators will learn to recognize the terms and symbols found on VFR (visual flight rules) and IFR (instrument flight rules) charts, and TPPs (terminal procedures publications).

This FAA publication explains all the symbology used on the FAA world aeronautical charts, sectional aeronautical, terminal area, flyway planning, helicopter route, enroute low- and high-altitude, area, and oceanic route charts, as well as standard terminal arrival routes, standard instrument departures, and instrument approach procedures. The chart legends and airspace classifications tables are included. 

The CUG-12 is now under a 56-day cycle. ASA will be publishing minor updates as they are available. Please visit ASA's website for any updates.
