Narrative:

During arrival into newark, while on the descent into the area, on the williamsport one arrival, we were instructed to cross sweet at 7000 ft. At the time we were at 13000 ft and it appeared that although it would require an aggressive descent, we could make it. Using flight idle and speed brakes, we started down. Due to heavy rapid traffic on the frequency, I was not able to advise approach that meeting the restr was questionable. The intent was to ask for a vector to help get rid of the altitude prior to crossing sweet intersection. As we crossed sweet, we were at 7500 ft MSL the controllers gave us a vector and continued descent to 6000 ft and nothing was said by approach control reference the crossing limit. I make a point to get down early. This time it was not possible due to the altitude and distance covered. A major contributing factor was the workload on the approach frequency which resulted in numerous blocked xmissions from both aircraft and controllers. P.south. During the events described there were no TCASII conflicts indicated. The closest target was 1100 ft below our flight path.

Title: FLC OF A EMBRAER 145 JET FAILED TO DSND IN TIMELY MANNER AND UNDERSHOT A XING RESTR BY 500 FT. ATC DID NOT COMMENT BUT SUBSEQUENTLY CLRED RPTR TO A LOWER ALT.

Narrative: DURING ARR INTO NEWARK, WHILE ON THE DSCNT INTO THE AREA, ON THE WILLIAMSPORT ONE ARR, WE WERE INSTRUCTED TO CROSS SWEET AT 7000 FT. AT THE TIME WE WERE AT 13000 FT AND IT APPEARED THAT ALTHOUGH IT WOULD REQUIRE AN AGGRESSIVE DSCNT, WE COULD MAKE IT. USING FLT IDLE AND SPD BRAKES, WE STARTED DOWN. DUE TO HVY RAPID TFC ON THE FREQ, I WAS NOT ABLE TO ADVISE APCH THAT MEETING THE RESTR WAS QUESTIONABLE. THE INTENT WAS TO ASK FOR A VECTOR TO HELP GET RID OF THE ALT PRIOR TO XING SWEET INTXN. AS WE CROSSED SWEET, WE WERE AT 7500 FT MSL THE CTLRS GAVE US A VECTOR AND CONTINUED DSCNT TO 6000 FT AND NOTHING WAS SAID BY APCH CTL REF THE XING LIMIT. I MAKE A POINT TO GET DOWN EARLY. THIS TIME IT WAS NOT POSSIBLE DUE TO THE ALT AND DISTANCE COVERED. A MAJOR CONTRIBUTING FACTOR WAS THE WORKLOAD ON THE APCH FREQ WHICH RESULTED IN NUMEROUS BLOCKED XMISSIONS FROM BOTH ACFT AND CTLRS. P.S. DURING THE EVENTS DESCRIBED THERE WERE NO TCASII CONFLICTS INDICATED. THE CLOSEST TARGET WAS 1100 FT BELOW OUR FLT PATH.
