Altitude constraint values associated with the Final Approach Fix (FAF) and waypoints beyond the FAF cannot
be designated for vertical guidance. These altitude values will always be displayed as white text, as in Figure

altitude source, therefore, the displayed altitude values are for reference only.

maintain the -2.5 FPA. To change the vertical flight path, perform the following steps.
