FLC LINED UP ON WHP ARPT RATHER THAN BUR.

Narrative

WE WERE ARRIVING IN BUR; USING THE FERN 5 ARR; WHEN SOCAL APCH ASKED IF WE WOULD LIKE A VISUAL APCH TO RWY 15. THE WX WAS CLR; 8 MI VISIBILITY; SO WE REPLIED IN THE AFFIRMATIVE. SOCAL ASSIGNED A HDG OF 110 DEGS AND SHORTLY THEREAFTER CLRED US TO DSND TO 3000 FT. I MADE A POSITIVE IDENT ON THE VNY ARPT BECAUSE I KNOW THE RWY ARRANGEMENT WAS SIMILAR TO BUR; AND I WANTED TO MAKE SURE I HAD BOTH ARPTS IN SIGHT. SOON I PICKED UP ANOTHER ROTATING BEACON AT THE R BEARING FROM OUR LOCATION AND POINTED IT OUT TO THE FO; WHO WAS FLYING. HE CONFIGURED FOR LNDG; AND BEGAN TO DSND OUT OF 3000 FT. SOON; I REALIZED THE PICTURE DIDN'T LOOK R AND TOLD HIM I THOUGHT WE WERE LINED UP ON THE WRONG ARPT. AT ABOUT THIS TIME BUR TWR DIRECTED A GAR; SAYING WE WERE LINED UP ON WHITEMAN ARPT (WHP). THEY GAVE US A L TURN WHICH PUT US ON A NICE R BASE FOR BUR. WE SPOTTED THE RWY IMMEDIATELY AND LANDED WITHOUT INCIDENT. IF WE HAD SET UP THE INS TO DISPLAY A 3 MI FINAL TO BUR; PERHAPS WE COULD HAVE AVOIDED THIS PROB. SUPPLEMENTAL INFO FROM ACN 425797: THE CAPT TOLD SOCAL THAT WE HAD BUR IN SIGHT AND THEY CLRED US FOR THE FOUR STACKS VISUAL APCH TO RWY 15 AT BUR; AND TO BUR TWR FREQ. BUR TWR HAD ALSO CAUGHT OUR ERROR AND ISSUED A TFC ALERT TO US AND GAVE US A SNAP VECTOR TOWARD BUR ARPT. THAT VECTOR ALLOWED US TO QUICKLY ACQUIRE BUR; CLRED THE CONSIDERABLE CONFUSION WE BOTH FELT AT THAT TIME; AND ALLOWED US TO EASILY TRANSITION TO AN OTHERWISE UNEVENTFUL LNDG AT BUR. BUR TWR TOLD US THAT THE ARPT WE HAD BEGUN OUR APCH TO WAS WHITEMAN ARPT; LOCATED 4.5 NM NW OF BUR. BUR TWR'S ACTIONS WERE NOTEWORTHY. THEY CAUGHT OUR ERROR AS QUICKLY AS I BELIEVE WOULD HAVE BEEN POSSIBLE; AND PROVIDED CLR AND CONCISE GUIDANCE WHICH WAS VERY HELPFUL IN OUR RECOVERY FROM THIS SIT.
