FLC MISSES XING ALT BY 1000 FT DURING DSCNT USING VNAV WITH FMC PROGRAMMED FOR THE DSCNT.

Narrative

DSNDING ON THE OGDEN 5 ARR; CLRED TO CROSS CARTR AT 16000 FT. WE HAD SLOWED FOR TURB. THERE WAS CONFUSION OVER THE XING ALT AND WE ASKED ZLC TO CONFIRM BECAUSE WE THOUGHT IT WAS FL190. ZLC CONFIRMED 16000 FT. THE ALT REMINDER WAS RECHKED AT 16000 FT. THERE WAS GLARE IN THE COCKPIT ON THE FMS CRT BUT I THOUGHT IT READ 16000 FT AT CARTR AS WELL. WE WERE MAKING AN FMS DSCNT ON VNAV; LNAV; WHEN THE CTR HANDED US TO APCH AND ASKED IF WE INTENDED TO MAKE THE CARTR XING RESTR. WE WERE HIGH SO I MANUALLY AND RAPIDLY DSNDED AND CROSSED CARTR APPROX 1000 FT HIGH. THERE WAS NO OTHER TFC AND WE WERE CLRED STRAIGHT IN TO INTERCEPT THE SLC RWY 16 LOC. THE APCH AND LNDG WERE UNEVENTFUL. CHAIN OF EVENTS: IT IS POSSIBLE I HAD 19000 FT IN THE FMS AND 16000 FT IN THE ALT REMINDER; BUT DUE TO GLARE; BOTH THE FO AND I FAILED TO CATCH THE DISCREPANCY. I DID NOTE THAT I WAS NEVER ABOVE THE PATH DSCNT PROGRAMMED BY THE FMS. WE WERE ALSO BUSY WITH THE DSCNT CHKLIST AT THIS TIME. WE MISSED XCHKING THE RAW DATA ON THE FO'S VOR DME AGAINST THE DSCNT THE FMS WAS FLYING. SUPPLEMENTAL INFO FROM ACN 299474: STILL AT FL190 AND 20 DME; APCH THEN ASSIGNED US 12000 FT. THE SUPVR WAS CALLED WHEN WE GOT ON THE GND TO SEE IF THERE MIGHT HAVE BEEN A CONFLICT. DON'T RELY ON THE 'MAGIC' EQUIP; EG; FMS TO GET THINGS DONE. IF WE WERE DOING AN AUTOPLT ONLY DSCNT; I DON'T THINK THIS WOULD HAVE HAPPENED. WE WERE LULLED INTO COMPLACENCY THINKING THE MAGIC WOULD DO IT.
