FLC DSNDS BELOW GS ALT ON ILS APCH.

Narrative

APPROX 30 NM OUT ON ARR TO EDBT AFTER OCEAN XING AND INTERMEDIATE STOP AT HAMBURG (EDDH). WE WERE CLRED FROM FL70 TO 3000 FT AND CLRED FOR THE APCH. THE ILS HAD BEEN IDENTED BY THE PLT IN RELIEF SEAT; ALL CHKS HAD BEEN COMPLETED DOWN TO 'LNDG.' CAPT FLYING BEGAN AN AGGRESSIVE DSCNT; AS HE HAD GOTTEN DOWN EARLY FOR ARR INTO EDDH; AND I WAS INITIALLY DISTRACTED BY CALL FOR FLAPS 5 DEGS WHILE WE WERE ABOVE FLAP SPD. HE THEN CALLED FOR GEAR TO SLOW US BUT KEPT DSCNT RATE. AT ABOUT 4000 FT I SAW THAT THE GS HAD CAPTURED ON THE ILS FLT DIRECTOR. ON ARR; EARLIER; TO HAMBURG WE WERE INSTRUCTED TO FOLLOW GS DOWN EVEN THOUGH WE HADN'T CAPTURED THE LOC AND I THINK THAT WAS PART OF THE MINDSET. THE FO THEN CALLED GOING THROUGH 2700 FT AND I AS PNF CONCERNED THAT WE WERE THROUGH THE ALT AND THAT WE WERE 17 NM FROM NORMAL 3000 FT GS INTERCEPT POINT. I RECYCLED THE FLT DIRECTOR AND RE- ENGAGED THE APCH COMMAND AND IT CAPTURED GS (FALSELY) AGAIN; ALTHOUGH IT DID BLINK SEVERAL TIMES. APCH CTL CALLED US ABOUT OUR ALT WHICH NOW WAS 2200 FT. THEREAFTER; WE DSNDED TO 2000 FT THEN CLBED TO 3000 FT AND REINTERCEPTED THE LOC AND GS. ALL ELSE WAS NORMAL THEREAFTER.
