What is the FMS Bridge Visual 28R approach at SFO?
The FMS Bridge Visual Approach 28R is a version of the Quiet Bridge Visual Approach 28R which is coded with GPS coordinates and can be included in an FMS database for approved operators.  This allows the procedure to be used when the SFO 
VOR is out of service, and also gives ATC additional flexibility by allowing them to clear pilots direct to any of the fixes without needing to intercept the radial on the standard arrival.

The pilot must either tell ATC that they can accept it verbally, or include FMS28R ABLE in the remarks of their flight plan so that they know that the flight is capable of flying the approach.
