CREW IN TURBO JET CROSS THE WRONG FIX AT 10000 FT AND UNDERSHOOT THE CROSSING RESTRICTION.

Narrative

THERE IS NO VERTICAL NAV INFO ON THE PMM4 ARR TO ORD. THE CAPT AND I HAD COMMENTED ON THAT FACT; AND HE AGREED WITH ME THAT WE'D PROBABLY CROSS PAPPI INTERSECT AT 10000 FT. WE WERE AT FL260; AND I COMPUTED THAT DSCNT SINCE ON OUR OLD STEAM GAUGE DC9; WE HAVE NO FORM OF VNAV-OR EVEN GND SPEED READOUT! WHEN WE WERE TOLD 'CROSS PIVOT AT 10000 FT I HEARD' PAPPI; PARTLY BECAUSE I HAD NOTICED THAT THERE ARE TWO INTXN ON THE SAME RADIAL 22 MILES HAVE 2 SYLLABLES. MY PLANNING FOR PAPPI WAS GOOD; BUT 22 MILES PAST WHERE I WAS SUPPOSED TO REACH 10000 FT. THE CAPT NOTICED THIS A BIT LATE AND DID NOT ASK ATC FOR RELIEF (WHICH I SHOULD HAVE TOLD HIM TO DO!) FULL SPEED BRAKES AND STEEPEST DSCNT LATER; I WAS ALMOST LEVEL AT 10000 FT BY PIVOT -BUT NOT QUITE! I DON'T FLY TO ORD OFTEN; AND EVEN MORE RARELY FROM DTW. BUT YOU SHOULDN'T HAVE T BE A 'REGULAR' TO KNOW WHAT TO EXPECT. 1) PUT 'EXPECT TO CROSS' INFO ON THIS ARR ASAP; EVEN THOUGH IT WILL BE EXTENSIVE; GIVEN ALL THE RWY CONFIGURATIONS AT ORD. 2)BE SURE THAT INTXN NAMES ALONG THE SAME ARR HAVE AS DIFFERENT A SOUND AS POSSIBLE! EVEN DOUBLE CHKING MYSELF IN THIS SIT DID NOT HELP; BECAUSE I HAD HEARD PAPPI; NOT PIVOT IN THE FIRST PLACE; AND POSSIBLY EVEN SAID 'PIVOT'-THINKING 67 MILES FROM PMM RATHER THAN 'OH THAT OTHER 'P' INTXN NAT 45 DME!' IN THE EFIS C525 I USED TO FLY IT WOULD HAVE BEEN RIGHT ON MY EHSI RIGHT IN FRONT OF MY FACE! THANKS FOR THIS GREAT ASRS PROGRAM.
