Again, it was redefined. Summary:
Until 2016: "Precision Final Approach Fix". Old meaning: glideslope intercept point on a Precision Approach (hence the name). It is not defined on NPA procedures. Operationally, the location would vary with actual altitude flown.
2016 redefinition: "Precise Final Approach Fix". New meaning: the calculated position (fixed) where the vertical path or glideslope intersects the intermediate segment altitude. It may be defined for all approach types (PA, APV, NPA). A "Precise" FAF must be locatable within +/- 1 NM using intended navaids (e.g., VORs) or up to +/- 2 NM in certain other circumstances.
