Apologies if this has been mentioned already;
From the flights ground track it appears that they were cleared for the TIPTOE Visual to runway 28L. This charted Visual procedure is slightly unusual in some ways, and includes some holes that the uninitiated may fall into; Especially after an eleven hour flight landing at a 3:30 AM circadian time.
1. Vertical guidance is only charted at two minimum altitudes. The last of which is published due to Class B airspace. This altitude leaves you high with regard to a 3 degree glide path.
2. With the GS out of service there is no Vertical guidance associated with the approach, apart from the PAPIs.
3. In some FMS databases the TIPTOE Visual must be 'built' in the FMS.
4. The approach can be flown accurately using a combination of LVAV/VNAV followed by IAN. This method allows both vertical and lateral guidance. It also requires familiarity and or training.
It doesn't appear from the vertical track posted that the crew were following IAN or the PAPI.
