Narrative:

I was the first officer and the captain was flying. We were on a flight from cleveland to chicago, midway. We were with ZAU on frequency 135.90 and he told us to cross 20 mi west of goshen at 10000 ft. I acknowledged, and captain repeated to me '20 west of goshen at 10.' I then switched to midway ATIS on #2 radio to get WX and then called in range to company. I noticed the captain was descending. When I came back on #1 radio I saw we were at about 13000 ft and 18 mi west of goshen. I told captain we were to be at 10000 ft 20 mi west of goshen the last I knew, and we wouldn't make it. I asked if there was a change when I was off the radio. He said no and that he could easily make the crossing restr. I said 'no we are there now!' he then noticed he was looking at the #2 DME which was set on chicago heights ahead of us instead of the #1 DME which was set on goshen, behind us. He pulled the speed brake and pushed the nose down while I grabbed the microphone to tell center. Center called before I could get a word in and told us to hurry to 10000 ft and that we had missed our restr. I responded and by this time we were at about 27 mi DME. About 20 seconds later we were level at 10000 ft and I told the controller. The captain was very angry with himself for misreading the DME and I was very angry with myself for not catching it sooner. (When I saw the captain descending slowly, for a second I thought the controller must have change the restr when I was off the radio. But when I questioned the captain I realized that wasn't the case). I was so busy attending my duties getting the WX at chicago that I guess it is impossible to do everything in the cockpit and I just got overloaded and missed the captain's mistake.

Title: COMPLIANCE WITH A DME XING RESTR WAS MADE IN REF TO THE WRONG NAVAID, RESULTING IN AN ACR FLC DEV.

Narrative: I WAS THE FO AND THE CAPT WAS FLYING. WE WERE ON A FLT FROM CLEVELAND TO CHICAGO, MIDWAY. WE WERE WITH ZAU ON FREQ 135.90 AND HE TOLD US TO CROSS 20 MI W OF GOSHEN AT 10000 FT. I ACKNOWLEDGED, AND CAPT REPEATED TO ME '20 W OF GOSHEN AT 10.' I THEN SWITCHED TO MIDWAY ATIS ON #2 RADIO TO GET WX AND THEN CALLED IN RANGE TO COMPANY. I NOTICED THE CAPT WAS DSNDING. WHEN I CAME BACK ON #1 RADIO I SAW WE WERE AT ABOUT 13000 FT AND 18 MI W OF GOSHEN. I TOLD CAPT WE WERE TO BE AT 10000 FT 20 MI W OF GOSHEN THE LAST I KNEW, AND WE WOULDN'T MAKE IT. I ASKED IF THERE WAS A CHANGE WHEN I WAS OFF THE RADIO. HE SAID NO AND THAT HE COULD EASILY MAKE THE XING RESTR. I SAID 'NO WE ARE THERE NOW!' HE THEN NOTICED HE WAS LOOKING AT THE #2 DME WHICH WAS SET ON CHICAGO HEIGHTS AHEAD OF US INSTEAD OF THE #1 DME WHICH WAS SET ON GOSHEN, BEHIND US. HE PULLED THE SPD BRAKE AND PUSHED THE NOSE DOWN WHILE I GRABBED THE MIKE TO TELL CTR. CTR CALLED BEFORE I COULD GET A WORD IN AND TOLD US TO HURRY TO 10000 FT AND THAT WE HAD MISSED OUR RESTR. I RESPONDED AND BY THIS TIME WE WERE AT ABOUT 27 MI DME. ABOUT 20 SECONDS LATER WE WERE LEVEL AT 10000 FT AND I TOLD THE CTLR. THE CAPT WAS VERY ANGRY WITH HIMSELF FOR MISREADING THE DME AND I WAS VERY ANGRY WITH MYSELF FOR NOT CATCHING IT SOONER. (WHEN I SAW THE CAPT DSNDING SLOWLY, FOR A SECOND I THOUGHT THE CTLR MUST HAVE CHANGE THE RESTR WHEN I WAS OFF THE RADIO. BUT WHEN I QUESTIONED THE CAPT I REALIZED THAT WASN'T THE CASE). I WAS SO BUSY ATTENDING MY DUTIES GETTING THE WX AT CHICAGO THAT I GUESS IT IS IMPOSSIBLE TO DO EVERYTHING IN THE COCKPIT AND I JUST GOT OVERLOADED AND MISSED THE CAPT'S MISTAKE.
