Narrative:
Flight to ewr, in cruise at 16000 ft MSL. Given heading 240 degrees to intercept V213 northeast of sax VOR, then given clearance to cross 25 mi northeast sax VOR at and maintain 7000 ft. Had already set sax VOR manually VOR radial intercept on V213. DME read about 60-70 mi. While putting crossing point into FMS, center told us to start down. It was then I realized DME now was about 40 mi and it would be hard to get to 7000 ft by 25 mi. Told controller and he said do the best we could. We made 7300 ft by 25 DME. The problem here was too much attention to FMS insertion lead to failure to calculate a manual descent to get down in time.

Title: CARGO JET FLC STARTS DSCNT LATE FOR XING RESTR AND FAILS TO MEET THE REQUIREMENTS. FLC GOT HUNG UP IN PROGRAMMING THE FMC BEFORE STARTING DOWN.
Narrative: FLT TO EWR, IN CRUISE AT 16000 FT MSL. GIVEN HDG 240 DEGS TO INTERCEPT V213 NE OF SAX VOR, THEN GIVEN CLRNC TO CROSS 25 MI NE SAX VOR AT AND MAINTAIN 7000 FT. HAD ALREADY SET SAX VOR MANUALLY VOR RADIAL INTERCEPT ON V213. DME READ ABOUT 60-70 MI. WHILE PUTTING XING POINT INTO FMS, CTR TOLD US TO START DOWN. IT WAS THEN I REALIZED DME NOW WAS ABOUT 40 MI AND IT WOULD BE HARD TO GET TO 7000 FT BY 25 MI. TOLD CTLR AND HE SAID DO THE BEST WE COULD. WE MADE 7300 FT BY 25 DME. THE PROB HERE WAS TOO MUCH ATTN TO FMS INSERTION LEAD TO FAILURE TO CALCULATE A MANUAL DSCNT TO GET DOWN IN TIME.
