Narrative:
We were flying the nickl one arrival to minneapolis, mn, and had been cleared to cross fredy at 10000'. Because of a previous complaint about the aircraft pressurization I was attempting initially to hold a slower than normal rate of descent and start the descent further out from fredy than normal. As the profile continued I became aware that fredy was rapidly approaching. At 18000' and 10 mi to go, speed brakes out and 4500'/min down, the captain informed ATC that we would not make 10000' by fredy and asked if that would be a problem. Center said no and we xed fredy at approximately 14000'. During the initial part of the descent the captain was getting the ATIS and talking to company on company frequency and so was not monitoring me as closely as he would otherwise. With only 60 hours in transport aircraft I did not have the experience to clue me in earlier that my initial rate of descent was not sufficient to make the crossing restriction. In retrospect I should have just followed the normal profile or planned earlier in the flight profile with clearly defined chkpoints to gauge progress on the descent so I would recognize problems in time to make good corrections.

Title: FLT CREW CLEARED CROSS FREDY AT 10000'. FLT CREW CROSSED AT 14000'.
Narrative: WE WERE FLYING THE NICKL ONE ARR TO MINNEAPOLIS, MN, AND HAD BEEN CLRED TO CROSS FREDY AT 10000'. BECAUSE OF A PREVIOUS COMPLAINT ABOUT THE ACFT PRESSURIZATION I WAS ATTEMPTING INITIALLY TO HOLD A SLOWER THAN NORMAL RATE OF DSNT AND START THE DSNT FURTHER OUT FROM FREDY THAN NORMAL. AS THE PROFILE CONTINUED I BECAME AWARE THAT FREDY WAS RAPIDLY APCHING. AT 18000' AND 10 MI TO GO, SPD BRAKES OUT AND 4500'/MIN DOWN, THE CAPT INFORMED ATC THAT WE WOULD NOT MAKE 10000' BY FREDY AND ASKED IF THAT WOULD BE A PROB. CTR SAID NO AND WE XED FREDY AT APPROX 14000'. DURING THE INITIAL PART OF THE DSNT THE CAPT WAS GETTING THE ATIS AND TALKING TO COMPANY ON COMPANY FREQ AND SO WAS NOT MONITORING ME AS CLOSELY AS HE WOULD OTHERWISE. WITH ONLY 60 HRS IN TRANSPORT ACFT I DID NOT HAVE THE EXPERIENCE TO CLUE ME IN EARLIER THAT MY INITIAL RATE OF DSNT WAS NOT SUFFICIENT TO MAKE THE XING RESTRICTION. IN RETROSPECT I SHOULD HAVE JUST FOLLOWED THE NORMAL PROFILE OR PLANNED EARLIER IN THE FLT PROFILE WITH CLRLY DEFINED CHKPOINTS TO GAUGE PROGRESS ON THE DSNT SO I WOULD RECOGNIZE PROBS IN TIME TO MAKE GOOD CORRECTIONS.
