The FAA change notice CS 16-02 CN that refers to the change in name for the "Green Book" does state that the complete book will now be called the Chart Supplement. However, the internal section that contains the individual airport information is still called the Airport and Facilities Directory (A/FD).
To comply with this change, we have renamed the complete publication found under the FAA catalog in the Documents section to "Chart Supplement". ForeFlight has kept the name "A/FD" on the Airports tab as CS 16-02 CN refers to those pages (pg. 1) formally as the "A/FD." We have also retained the name "A/FD" due to its standard usage by pilots.
