Narrative:

We were inbound at XA30. First officer flying. Bay approach turned us in tight for ILS runway 28R well above GS. First officer tried unsuccessfully to capture GS from above. Still outside brijj, aircraft captured MCP altitude and began to slow. Speed slowed to 5-10 KTS below reference before first officer was able to disconnect autoplt and recover. In retrospect, I should have taken control of the aircraft. Main cause was bay's inappropriate vectoring to the ILS above the GS which they do all the time. There was no other traffic and this was an unnecessary high dive. Bad procedure for XA30 arrival.

Original NASA ASRS Text

Title: B777 INBOUND TO SFO IS VECTORED TO INTERCEPT ILS LOC WELL ABOVE THE GS.

Narrative: WE WERE INBOUND AT XA30. FO FLYING. BAY APCH TURNED US IN TIGHT FOR ILS RWY 28R WELL ABOVE GS. FO TRIED UNSUCCESSFULLY TO CAPTURE GS FROM ABOVE. STILL OUTSIDE BRIJJ, ACFT CAPTURED MCP ALT AND BEGAN TO SLOW. SPD SLOWED TO 5-10 KTS BELOW REF BEFORE FO WAS ABLE TO DISCONNECT AUTOPLT AND RECOVER. IN RETROSPECT, I SHOULD HAVE TAKEN CTL OF THE ACFT. MAIN CAUSE WAS BAY'S INAPPROPRIATE VECTORING TO THE ILS ABOVE THE GS WHICH THEY DO ALL THE TIME. THERE WAS NO OTHER TFC AND THIS WAS AN UNNECESSARY HIGH DIVE. BAD PROC FOR XA30 ARR.
