FLC OF A B727 DOES NOT MAKE THE XING RESTR AS ASSIGNED.

Narrative

FO FLYING THE ACFT ON THE MARVEL 3 ARR INTO MEM. CLRED DIRECT MARVEL WITH A XING RESTR OF 12000 FT; 4 MI NE OF MARVEL. LEAVING CRUISE ON THE DSCNT; I TOLD THE FO WE APPEARED TO BE HIGH FOR THE UPCOMING XING RESTR; HOWEVER; SPD BRAKES WERE NOT BEING USED AT THE PRESENT TIME. FULL SPD BRAKES WOULD CORRECT BEING HIGH; AND THIS PROFILE IS OFTEN USED. THE SO HAD GIVEN US THE LNDG CARD LATER THAN I LIKE FOR A TIMELY SETUP. BUG SPDS WERE SET AND THE APCH BRIEFED. THE FO BRIEFED A DIFFERENT APCH AND WE DID NOT DO OUR 'IN RANGE' CHKLIST AT FL180 AS NORMALLY DONE. THESE DISTRS PREVENTED MY NORMAL ALT XCHKING DSCNT FORMULA PATTERN; AND WITH A 70 KTS TAILWIND THE FO WAS HIGH. OVER TAMMY (4 MI NE OF MARVEL) WE WERE HIGH 900 FT WITH A HIGH RATE OF DSCNT. THE DISTRS MENTIONED COULD HAVE BEEN AVOIDED WITH AN EARLIER SETUP FOR THE APCH. WE ALSO HAD 2 COCKPIT JUMP SEATERS THAT HAD BEEN ENGAGING IN MUCH CONVERSATION ON THIS FLT. OUR DISCUSSIONS COULD HAVE BEEN REDUCED. IN ADDITION; MY ALERTNESS WAS LIMITED DUE TO FATIGUE. DURING OUR LAYOVER THE PREVIOUS 2 NIGHTS; I HAD ABOUT 10 HRS TOTAL SLEEP. NORMALLY; I SLEEP 8 HRS A NIGHT. THIS WAS MY FIRST FLT WITH THIS FO AS THE PF; AND OUR SECOND FLT AS A CREW.
