A couple of years ago the FAA commissioned a new ILS to KGYI (Grayson
County Airport in TX). It included an ADF. There were two more ILS
approaches in the area that did not have ADF requirements and they were
added. For the life of me I do not understand why. for KGYI there were
several ways to locate the FAF.

Its recently been added as a resquirement for the ILS 02 for KSAC. For
decades we've been flying that approach w/o ADF, apparently the FAA has
recently decided that ADFs are important.

Hello all,

I'm just curious as to when the last time was that you used your ADF
for actual navigation? Are NDBs common in the US? It seems as though
every little airport has an ILS!
