Is there a relatively simple way to add the many missing navaids especially new ILS installations?ThanksChris

If you're using FS2002 it's easy, http://perso.wanadoo.fr/hsors/FS_Soft/easynavs.html but there's no way that I know to how in FS2004.

I think you need Lee Swordy's free AFCAD 2.21. I put an NBD at Antelope Trails Ranch.
