The Flight Safety Foundation, Inc. conducted a study to research and develop a process to identify and ultimately cancel underutilized or redundant instrument approach procedures. The FAA has used the information from this study to establish criteria to use when selecting procedures for proposed cancellation.
Webdatasheet is the FAA repository of airport and NAVAID data to include the assigned magnetic variation.
Docushare contains all pertinent documentation of all published instrument flight procedure source documentation to include magnetic variation assigned to the instrument flight procedure.
The table below provides announcements and reports related to new Instrument Approach Procedure (IAP) development in the National Airspace System (NAS).
