Narrative

WE WERE DEVIATING AROUND TSTMS TO LAND AT PBI; ENRTE FROM FLL. WE WERE FARTHER TO THE E THAN WE NORMALLY FLEW. WE SAW AN ARPT THAT WE THOUGHT WAS PBI; AND WERE CLRED FOR THE VISUAL WITH INSTRUCTIONS TO CROSS OVER THE RUBIN LOM; FOR NOISE ABATEMENT PURPOSES. THE CAPT STARTED TURING EARLY; SO I POINTED TO THE ADF AND REPEATED OUR CLRNC WAS TO CROSS OVER RUBIN. SINCE I WAS NOW CERTAIN THAT THE CAPT UNDERSTOOD OUR INSTRUCTIONS AND I HAD OBSERVED HIM TURN BACK TOWARDS THE BEACON; I ASSUMED HE WOULD WAIT FOR THE LOC TO COME ALIVE; AND THE OTHER NAV SOURCES TO AGREE; BEFORE HE TURNED FINAL; SO I DIVERTED MY ATTN OUTSIDE TO LOOK FOR TFC; AS THIS WAS A VERY BUSY AREA; WITH LOTS OF LIGHT PLANE ACTIVITY. AS HE LINED UP ON FINAL; WE BOTH NOTICED THAT THIS DIDN'T LOOK RIGHT. OUR ADF NEEDLES WERE POINTING TO OUR 7 O'CLOCK; SO I LOOKED TO THE L AND SAW PBI. I POINTED IT OUT TO THE CAPT AND HE INITIATED A TURN TO THE L AND A CLB. ABOUT THIS TIME PBI TWR CALLED TO TELL US WE HAD LINED UP ON LATANA ARPT; WHICH HAS THE SAME RWY ORIENTATION; AND THEY GAVE US VECTORS TO PBI. HOWEVER; WE WERE ALREADY IN TO TURN BY THEN. EARLIER; WHEN WE HAD CALLED PBI TWR; THEY HAD CLRED US TO LAND; EVEN THOUGH WE HAD LINED UP ON THE WRONG ARPT.
