The Aeronautical Charting Forum is a public forum held two times every year and is the primary method of adding and modifying charting specifications. The Aeronautical Charting Forum is divided into two groups – the Instrument Procedures Group (IPG) and the Charting Group (CG). See Order 7910.5.

The RD Status-Open and RD History-Closed tabs below provide information regarding specific Recommendation Documents (RDs) being worked or have been completed.

The Instrument Procedures Group portion of the ACF includes briefings and discussions on recommendations regarding pilot procedures for instrument flight, as well as criteria, design, and developmental policy for instrument approach and departure procedures.

For information regarding charting issues, please visit ACF Charting Group.
