I have heard some say a FAF does not exist on a precision approach according to ICAO, and that it is technically a FAP. While, most of the ICAO documents lead to believe that is true I have found one particular statement that makes me think otherwise (ICAO-8168):
22.214.171.124 The approach segments begin and end at designated fixes. However, under some circumstances certain of
the segments may begin at specified points where no fixes are available. For example, the final approach segment of a
precision approach may start where the intermediate flight altitude intersects the nominal glide path (the final approach
Note.— See Chapters 2 to 6 of this section for detailed specifications on approach segments.
Notice it says "MAY start at a FAP" that leads me to believe it MAY not, and thus starts at a FAF.
In addition the FAA, and I know the FAA can be different, clearly defines in the pilot controller glossary a FAF as the point at which the final approach segment begins, and is indicated by a multese cross (NPA) or a lighting bold (precision approach). Therefore the FAA indicates a FAF (by a lighting bolt) on a PA.
Some may argue that a Final Approach FIX on a precision approach is not a FIX, that is why it does not exist on a PA. However, the definition of a Fix according to the FAA is a geographic point of reference with regard to visual aid, NAVAID, or another navigation device. The glide slope and the intermediate approach altitude DOES exist at a geographic point defined by "another navigation aid." Thus the Point at which an aircraft intercepts the minimum glide slope intercept altitude, IS a FAP AND According the the FAA is also a FAF.
Now my question is, how accurate is my analysis, and can anyone shed any additional light onto this topic.
