SAC ILS "ADF Required" Info

I just got some information back from the FAA on why an ADF is now
required after several decades of being able to fly the approach w/o
the ADF....

"Mr. Gary: The FAA Flight Procedures Office has issued a NOTAM
amendment 22C. This amendment states that the ILS Runway 02 approach at
SAC Airport requires ADF due to the inbound course 015 degrees is off
by 1 degree starting at the Coups IAF to the VOR. This procedure can
still be flown with GPS if an ADF is not available. The FAA has stated
that this approach will be amended in the future to realign the
approach course, probably using the Vortac. This does not effect the
future decommissioning of the NDB at SAC. Flight Service might have
more information if you need it. "
