FMS bridge visual [Runway] 28. Scattered low clouds. The pilot flying went below visual glide slope with four red showing on the PAPI. The pilot not flying mentioned we were low and the pilot flying slowed the rate of descent.We needed to pay closer attention to visual indications and should have refused a visual in marginal conditions. The crew was debriefed following the incident.
A Check Airman reported the pilot flying had descended well below the visual glide slope on the Runway 28 charted Visual BRIJJ approach to SFO before being alerted by the pilot not flying. The descent was arrested and the landing completed.
