Narrative:

All night flight lax-mia started descent from FL350 using distance on FMS. FMS was programmed direct mia, break in route, then the approach for runway 9L. Cleared for descent to 10000 ft then 3000 ft. Out of 30000 ft realized we were high and used speed brakes. Out of about 15000 ft given vectors to intercept ILS final. Still high. First officer was unable to put intercept leg into FMS so I tried. Still high, now fast. Still couldn't program FMS correctly. Caught myself going through 10000 ft at 300 KTS. Leveled off at about 8700 ft then slowed to 250 KTS. All nighters, erroneous FMS data, FMS problems, and high, fast dscnts don't mix. Supplemental information from acn 475552: we were doing an approach into mia. We began a late descent, so we were high. Began descent and then got preoccupied with putting the proper ILS approach in the FMS. Between the combination of starting a late descent, problem with the FMS, and doing an all night flight, we got behind. Although I made the proper call to make the captain aware we were approaching 10000 ft, my preoccupation with the FMS distracted me from realizing he failed to slow. Immediately at 10000 ft, we eventually made the discovery and began to slow at approximately 9500 ft.

Title: B757 CREW HAD SPD DEV IN MIA CLASS E.

Narrative: ALL NIGHT FLT LAX-MIA STARTED DSCNT FROM FL350 USING DISTANCE ON FMS. FMS WAS PROGRAMMED DIRECT MIA, BREAK IN RTE, THEN THE APCH FOR RWY 9L. CLRED FOR DSCNT TO 10000 FT THEN 3000 FT. OUT OF 30000 FT REALIZED WE WERE HIGH AND USED SPD BRAKES. OUT OF ABOUT 15000 FT GIVEN VECTORS TO INTERCEPT ILS FINAL. STILL HIGH. FO WAS UNABLE TO PUT INTERCEPT LEG INTO FMS SO I TRIED. STILL HIGH, NOW FAST. STILL COULDN'T PROGRAM FMS CORRECTLY. CAUGHT MYSELF GOING THROUGH 10000 FT AT 300 KTS. LEVELED OFF AT ABOUT 8700 FT THEN SLOWED TO 250 KTS. ALL NIGHTERS, ERRONEOUS FMS DATA, FMS PROBS, AND HIGH, FAST DSCNTS DON'T MIX. SUPPLEMENTAL INFO FROM ACN 475552: WE WERE DOING AN APCH INTO MIA. WE BEGAN A LATE DSCNT, SO WE WERE HIGH. BEGAN DSCNT AND THEN GOT PREOCCUPIED WITH PUTTING THE PROPER ILS APCH IN THE FMS. BTWN THE COMBINATION OF STARTING A LATE DSCNT, PROB WITH THE FMS, AND DOING AN ALL NIGHT FLT, WE GOT BEHIND. ALTHOUGH I MADE THE PROPER CALL TO MAKE THE CAPT AWARE WE WERE APCHING 10000 FT, MY PREOCCUPATION WITH THE FMS DISTRACTED ME FROM REALIZING HE FAILED TO SLOW. IMMEDIATELY AT 10000 FT, WE EVENTUALLY MADE THE DISCOVERY AND BEGAN TO SLOW AT APPROX 9500 FT.
