One useful part of that video is how they play clips of ATC telling flights to “join the localizer”. SFO has two published visual approaches (https://www.airnav.com/airport/KSFO https://www.airnav.com/airport/KSFO, scroll to the bottom): Both visual approaches have pilots fly to intercept their runway’s localizer, the part of the ILS equipment that provides lateral positioning, relative to the localizer’s centerline (which is generally coincident to the corresponding runway’s centerline). So, by flying the published visual approach and remaining “on the localizer”, you have separation from the planes on the parallel runway. What’s missing is careful monitoring and separation, and that’s what Lufthansa wanted. It’s worth noting that SFO does have a Simultaneous Offser Instrument Approach procedure: See https://www.tc.faa.gov/its/worldpac/techrpt/afs420-84-1.pdf https://www.tc.faa.gov/its/worldpac/techrpt/afs420-84-1.pdf (detail) or https://www.flysfo.com/sites/default/files/PRM_SOIA_version_1_0.pdf https://www.flysfo.com/sites/default/files/PRM_SOIA_version_... (summary). But that procedure requires, among other things, additional controllers handling approach and monitoring. SFO might not have the spare controllers right now.
