Narrative:

On approach to ord from south with late runway assignment to ILS runway 22R. As PF, I had planned for and selected visual runway 22L in FMS. Upon receiving the assignment for ILS runway 22R, I changed frequency and course for runway 22R, but forgot to change the FMS for runway 22R. FMS should generate a frequency mismatch message on the flight display but did not in this case. Controller was very busy and had us on a close parallel course, which resulted in a 'tight' turn to final. During the turn to final, I was in map mode while captain was in raw data. Because I had not changed the FMS from runway 22L to ILS runway 22R, my map display showed me about to overly final. Subsequently, the controller requested us to tighten our turn. 3 things happened at this time to complicate the situation: 1) controller request to tighten turn to 240 degrees, 2) TA from aircraft north of course being vectored to final, 3) FMS map presentation showing overshoot. In reality, we had not yet reached runway 22R localizer/centerline. Because ILS runway 22R has no DME, captain had been monitoring ord VOR until our turn to base. He then switched to ILS runway 22R to monitor raw data for localizer intercept and was able to make the call to me that we were still south of localizer and to correct back to the north. At this time the captain visually acquired both runways 22L and 22R and we continued our connection to runway 22R centerline. During our maneuver correcting to centerline, air carrier flight questioned the controller about our flight path and spacing for landing. To our knowledge, no evasive or abnormal maneuvering was required. At about 3-4 mi on final, we realized the FMS mistake. Landing was uneventful and we debriefed the event. Factors: late runway assignment. No DME for ILS runway 22R. Tight turn to final from south with aircraft turning base north off course resulting in TA. No frequency miss-match message on FMS. Wrong runway assignment in FMS.

Title: ON APCH TO RWY 22R AT ORD, DUE TO BREAKDOWN IN COCKPIT PROTOCOL, AN IMPROPER CONFIGN OF NAV COMPONENTS RESULTED IN CONFUSION REGARDING THE MD80'S POS RELATIVE TO ITS CLRNC. INPUTS TO THE FMS AFFECTING BOTH PLTS WERE MADE WITHOUT MONITORING OR VERIFICATION. A CONFLICT WITH AN ACR B737 CORRECTLY ON COURSE TO PARALLEL RWY 22L RESULTED.

Narrative: ON APCH TO ORD FROM S WITH LATE RWY ASSIGNMENT TO ILS RWY 22R. AS PF, I HAD PLANNED FOR AND SELECTED VISUAL RWY 22L IN FMS. UPON RECEIVING THE ASSIGNMENT FOR ILS RWY 22R, I CHANGED FREQ AND COURSE FOR RWY 22R, BUT FORGOT TO CHANGE THE FMS FOR RWY 22R. FMS SHOULD GENERATE A FREQ MISMATCH MESSAGE ON THE FLT DISPLAY BUT DID NOT IN THIS CASE. CTLR WAS VERY BUSY AND HAD US ON A CLOSE PARALLEL COURSE, WHICH RESULTED IN A 'TIGHT' TURN TO FINAL. DURING THE TURN TO FINAL, I WAS IN MAP MODE WHILE CAPT WAS IN RAW DATA. BECAUSE I HAD NOT CHANGED THE FMS FROM RWY 22L TO ILS RWY 22R, MY MAP DISPLAY SHOWED ME ABOUT TO OVERLY FINAL. SUBSEQUENTLY, THE CTLR REQUESTED US TO TIGHTEN OUR TURN. 3 THINGS HAPPENED AT THIS TIME TO COMPLICATE THE SIT: 1) CTLR REQUEST TO TIGHTEN TURN TO 240 DEGS, 2) TA FROM ACFT N OF COURSE BEING VECTORED TO FINAL, 3) FMS MAP PRESENTATION SHOWING OVERSHOOT. IN REALITY, WE HAD NOT YET REACHED RWY 22R LOC/CTRLINE. BECAUSE ILS RWY 22R HAS NO DME, CAPT HAD BEEN MONITORING ORD VOR UNTIL OUR TURN TO BASE. HE THEN SWITCHED TO ILS RWY 22R TO MONITOR RAW DATA FOR LOC INTERCEPT AND WAS ABLE TO MAKE THE CALL TO ME THAT WE WERE STILL S OF LOC AND TO CORRECT BACK TO THE N. AT THIS TIME THE CAPT VISUALLY ACQUIRED BOTH RWYS 22L AND 22R AND WE CONTINUED OUR CONNECTION TO RWY 22R CTRLINE. DURING OUR MANEUVER CORRECTING TO CTRLINE, ACR FLT QUESTIONED THE CTLR ABOUT OUR FLT PATH AND SPACING FOR LNDG. TO OUR KNOWLEDGE, NO EVASIVE OR ABNORMAL MANEUVERING WAS REQUIRED. AT ABOUT 3-4 MI ON FINAL, WE REALIZED THE FMS MISTAKE. LNDG WAS UNEVENTFUL AND WE DEBRIEFED THE EVENT. FACTORS: LATE RWY ASSIGNMENT. NO DME FOR ILS RWY 22R. TIGHT TURN TO FINAL FROM S WITH ACFT TURNING BASE N OFF COURSE RESULTING IN TA. NO FREQ MISS-MATCH MESSAGE ON FMS. WRONG RWY ASSIGNMENT IN FMS.
