The FAA had previoulsy indicated it was going to discontinue the FAA Chart Users Guide, but in a FAA Notice issued on August 13, 2025 the FAA noted that it would not discontinue the guide now, but that:

“The FAA will continue to publish the Aeronautical Chart Users Guide. However, beginning August 7, 2025, updates will no longer follow the regular 56-day charting schedule. Instead, revisions will be made on an as-needed basis to reflect changes or corrections.”
