This Chart User's Guide - "Aeronautical Chart User's Guide" - is an introduction to the Federal Aviation Administration's (FAA) aeronautical charts and publications. It is useful to new pilots as a learning aid, and to experienced pilots as a quick reference guide. The FAA is the source for all data and information utilized in the publishing of aeronautical charts for each stage of Visual Flight Rules (VFR) and Instrument Flight Rules (IFR) air navigation including training, planning, and departures, enroute (for low and high altitudes), app roaches, and taxiing charts.
