a) FAA 8260.19 is a source document for what I think you are looking for
(Including changes 1 & 2)
http://av-info.faa.gov/terps/Directi...s/8260.19C.pdf
b) Policy 01022, Documentation of Radar Requirements on Instrument
Approach
Procedures
http://av-info.faa.gov/terps/Policies1/TIL01022.pdf


1) "ADF Required" - Par 814-h
-- on an ILS, most likely a NDB is used for the missed approach
2) "RADAR Required" - Par 814-g, and TILS 01022
-- What I have seen is that the IAF is defined off of the localizer beam
at some specific DME/crossing radial, or again, required for the missed


Thank you. That explains how these notes appear on the plates, and suggests
why "ADF REQUIRED" appears on plates that can be flown completely without
ADF.
