FAF/FAP both designate the start of the final approach segment and if you don't know how to determine the location of the FAF or FAP you shouldn't be flying under IFR.
Based on some of your other posts you are a Canadian who commutes to Hong Kong to be a crewmember of a widebody airliner. Therefore, you shouldn't be flying under IFR. Maybe you're an SO, in which case you DON'T fly at ALL.
