FLC OF LGT FAILS TO COMPLY WITH SPD RESTR ON DSCNT USING STAR.

Narrative

WE WERE ON 1ST LEG OF THE DAY. A SHORT FLT FROM PDX TO SEA. THE CAPT WAS NEW -- LESS THAN 100 HRS AS CAPT AND ON ACFT. FAA WAS IN JUMPSEAT. I WAS 'PF.' I HAVE BEEN ON THE ACFT FOR ABOUT 5 MONTHS IN A PERIOD OF 18 MONTHS WITH OTHER TIME SPENT FLYING A NON-AUTOMATED ACFT. WE WERE BOTH BUSY WITH DUTIES; WHEN WE WERE GIVEN A CLRNC TO DSND TO 11000 FT (CROSS FOURT AT 11000 FT). I PERFORMED THE DSCNT AND THEN SELECTED 340 DEG HDG AT FOURT PER THE STAR. THE FAA INSPECTOR SAID SOMETHING TO ME ABOUT NEEDING 250 KTS. I DIDN'T UNDERSTAND WHY BUT STARTED TO SLOW (FROM ABOUT 275 KTS). DURING THIS TIME THE CAPT WAS OUT OF THE LOOP DOING SOMETHING WITH THE COMPUTER -- I DIDN'T KNOW WHAT. ONCE AT THE GATE THE INSPECTOR ASKED IF FOURT HAD A 250 KT RESTR -- IT DOES; BUT I MISSED IT. I WAS RELYING ON THE ATC CLRNC; WHICH DID NOT MENTION A SPD. CONTRIBUTING FACTORS: I'M NOT USED TO SEA SIDS/STARS WHICH USE THIS RESTR AND CAPT OUT OF LOOP; SO THE STAR WAS NOT BRIEFED. THE CAPT HAD SEEN A NOTAM CHANGING THE ILS RWY 16R COURSE FROM 158 DEGS TO 161 DEGS BUT OUR DATABASE SAID 158 DEGS. HE WAS TRYING TO MODIFY THE COURSE -- WHICH IS NOT POSSIBLE. IT DOESN'T MATTER ANYWAY; SINCE WE FLEW THE LOC SIGNAL; NOT RNAV. THE FAA INSPECTOR SEEMED CONFUSED ON THIS POINT AS WELL.
