I believe that at SFO the approaches are the LDA/DME 28R and the BAY
ILS/DME 28L, as well as the 28L and 28R visual approaches. Parallel
operations are only permitted during daylight hours, with ceiling
better than 2100' and visibility better than 6 miles. These are not
independent approaches - the trailing a/c must maintain visual
separation and ATC will place it at least 3/4 NM behind the lead
a/c. Passing is not allowed, and "wingtip-to-wingtip flight is not
permitted". If the lead a/c is a "heavy", additional separation is

(The new Denver airport does have runways far enough apart to allow
multiple independent approaches in IMC.)
