Narrative:

This is a comment on the lda runway 28R sfo. In general, approach control kept us high and fast. They cleared us for the approach late and created a rushed situation. Everything worked out okay, but it's difficult to fly a non-precision approach with a bad setup by approach control and still keep visual separation with a nearby aircraft. This approach is not yet in the A320 database. This is a hazardous approach. At the very least, the stagger distance should be 1 1/2 mi. Aircraft on the lda should be cleared to 6000 ft at aadam and cleared for the approach shortly after aadam. Any approach that requires 16 paragraphs of description is unsafe. Is a GS possible?

Title: SFO RWY 28R LDA DME APCH EVALUATION.

Narrative: THIS IS A COMMENT ON THE LDA RWY 28R SFO. IN GENERAL, APCH CTL KEPT US HIGH AND FAST. THEY CLRED US FOR THE APCH LATE AND CREATED A RUSHED SIT. EVERYTHING WORKED OUT OKAY, BUT IT'S DIFFICULT TO FLY A NON-PRECISION APCH WITH A BAD SETUP BY APCH CTL AND STILL KEEP VISUAL SEPARATION WITH A NEARBY ACFT. THIS APCH IS NOT YET IN THE A320 DATABASE. THIS IS A HAZARDOUS APCH. AT THE VERY LEAST, THE STAGGER DISTANCE SHOULD BE 1 1/2 MI. ACFT ON THE LDA SHOULD BE CLRED TO 6000 FT AT AADAM AND CLRED FOR THE APCH SHORTLY AFTER AADAM. ANY APCH THAT REQUIRES 16 PARAGRAPHS OF DESCRIPTION IS UNSAFE. IS A GS POSSIBLE?
