The FS9 Navaids package will update FS9 navigational aids (VORs, NDBs) in selectable FS9 world areas (worldwide coverage). Airport data (including ILSs and runway identifiers) can also be updated in Europe countries (those included in the Eurw and Eure FS9 folders).
An installer is provided and all original FS9 files are saved and can be restored. A PDF documentation is included. Be aware of some limitations/problems that may occur for those still using FS integrated flight planning (obsolete) or map view. See chapter 5 of documentation for details.
