Narrative:

I filed IFR for a flight from my home base, cedar rapids, ia (cid) to dupage, il (dpa). The WX was VFR excellent visibility. I made sure there were appropriate en route charts and approach plates in the cockpit. We use the chart service whereby the subscriber is periodically sent a completely revised set of approach plates and also sent 8 periodical updates which are filed behind tabs - the concept is that the pilot checks the latest tab index prior to departure to see if any relevant plates have been updated. For some inexplicable reason, I did not take this step (check for revisions). This may have been partially caused by the fact that the complete revision was quite new - 2 of the 8 updates had been received. In the briefing I received prior to filing, mention was made of a NOTAM at dupage relating to runway 1. I know the ILS was on runway 10 the NOTAM momentarily confused me and I did not resolve my confusion. As I approached dupage, I tuned in the localizer for 10 and noted that my approach was almost perfectly lined up with 10. The ATIS indicated runway 15-33 was closed so given the airport diagram I was using, it was clear to me that I would be landing on 10...which was in use according to the ATIS. Actually, I think the ATIS said 'landing and departing runway 10 landing runway 1L'. Runway 10 aid 1L confused and disoriented me - especially given the fact I was using an outdated airport diagram. I asked the extremely busy chicago center controller for clarification - he responded (I think) and his answer was unintelligible to me. When I saw the airport, chicago approach cleared me for the visual (to 1L) and instructed me to go to tower. Now on tower frequency, I was a little stunned to realize the airport in view was most certainly not he dupage I knew and at which I occasionally landed. I confessed my confusion to the tower as I overflew the approach (did not turn final on 1L). They gave me appropriate instructions to get me back in a final approach confign and I landed without further incident. This is not to say my confusion and disorientation did not cause ATC problems - they were busy and I'm sure I was a problem for them.

Title: PLT UNFAMILIAR WITH DUPAGE ARPT LOCATED AND SAW THE ARPT BUT UNAWARE OF NEW RWYS THOUGHT HE WAS AT WRONG ARPT AND PULLED OUT OF APCH PATTERN.

Narrative: I FILED IFR FOR A FLT FROM MY HOME BASE, CEDAR RAPIDS, IA (CID) TO DUPAGE, IL (DPA). THE WX WAS VFR EXCELLENT VISIBILITY. I MADE SURE THERE WERE APPROPRIATE ENRTE CHARTS AND APCH PLATES IN THE COCKPIT. WE USE THE CHART SVC WHEREBY THE SUBSCRIBER IS PERIODICALLY SENT A COMPLETELY REVISED SET OF APCH PLATES AND ALSO SENT 8 PERIODICAL UPDATES WHICH ARE FILED BEHIND TABS - THE CONCEPT IS THAT THE PLT CHKS THE LATEST TAB INDEX PRIOR TO DEP TO SEE IF ANY RELEVANT PLATES HAVE BEEN UPDATED. FOR SOME INEXPLICABLE REASON, I DID NOT TAKE THIS STEP (CHK FOR REVISIONS). THIS MAY HAVE BEEN PARTIALLY CAUSED BY THE FACT THAT THE COMPLETE REVISION WAS QUITE NEW - 2 OF THE 8 UPDATES HAD BEEN RECEIVED. IN THE BRIEFING I RECEIVED PRIOR TO FILING, MENTION WAS MADE OF A NOTAM AT DUPAGE RELATING TO RWY 1. I KNOW THE ILS WAS ON RWY 10 THE NOTAM MOMENTARILY CONFUSED ME AND I DID NOT RESOLVE MY CONFUSION. AS I APCHED DUPAGE, I TUNED IN THE LOC FOR 10 AND NOTED THAT MY APCH WAS ALMOST PERFECTLY LINED UP WITH 10. THE ATIS INDICATED RWY 15-33 WAS CLOSED SO GIVEN THE ARPT DIAGRAM I WAS USING, IT WAS CLR TO ME THAT I WOULD BE LNDG ON 10...WHICH WAS IN USE ACCORDING TO THE ATIS. ACTUALLY, I THINK THE ATIS SAID 'LNDG AND DEPARTING RWY 10 LNDG RWY 1L'. RWY 10 AID 1L CONFUSED AND DISORIENTED ME - ESPECIALLY GIVEN THE FACT I WAS USING AN OUTDATED ARPT DIAGRAM. I ASKED THE EXTREMELY BUSY CHICAGO CTR CTLR FOR CLARIFICATION - HE RESPONDED (I THINK) AND HIS ANSWER WAS UNINTELLIGIBLE TO ME. WHEN I SAW THE ARPT, CHICAGO APCH CLRED ME FOR THE VISUAL (TO 1L) AND INSTRUCTED ME TO GO TO TWR. NOW ON TWR FREQ, I WAS A LITTLE STUNNED TO REALIZE THE ARPT IN VIEW WAS MOST CERTAINLY NOT HE DUPAGE I KNEW AND AT WHICH I OCCASIONALLY LANDED. I CONFESSED MY CONFUSION TO THE TWR AS I OVERFLEW THE APCH (DID NOT TURN FINAL ON 1L). THEY GAVE ME APPROPRIATE INSTRUCTIONS TO GET ME BACK IN A FINAL APCH CONFIGN AND I LANDED WITHOUT FURTHER INCIDENT. THIS IS NOT TO SAY MY CONFUSION AND DISORIENTATION DID NOT CAUSE ATC PROBLEMS - THEY WERE BUSY AND I'M SURE I WAS A PROBLEM FOR THEM.
