folks, look at Quiet Bridge procedure, the offset is to threshold. Note the runway is at 284, while the approach is 275 until threshold.(not to 4nm as I have seen posted) As a reminder, it is a visual approach.
Thanks underfire; however, further down the chart (not visible on your excerpt) it says:
Aircraft should remain on the SFO R-095 until passing the San Mateo Bridge
So, presumably after this position they are free to align with the runway.
This is at SFO 6D, or 5nm from the threshold. My Lido chart shows an alignment manoeuvre with the runway at this point.
