Narrative:

Cleared for visual to runway 17 a J mco. First officer flying aircraft. Approach controller advised us of traffic landing on runway 18R. He appeared on TCASII. Switched over to tower and TCASII gives us an RA. On initial contact I was looking for aircraft that was giving RA and could not hear tower due to TCASII. When I looked at our position, noticed first officer was lined up for runway 18L. Immediately directed aircraft to turn back to runway 17 and then gave first officer the aircraft back. Contacted tower again (or simultaneously as we moved back). On landing, tower said no problem. First officer realized things didn't look right but never voiced concern until we discussed it on ground. One of the underlying problems in this event was that we were in a semi-slam dunk, thus faster than normal airspeed. I believe this caused the initial overshoot and then when confused, the first officer did not immediately voice his concern. He is definitely an above average first officer which probably lulled me into concentrating on the RA than our current situation. I discovered when I talked with tower (on the phone) that their initial call was for us to immediately get back to runway 17 which was unheard due to TCASII. The lesson I've learned: don't get complacent with good help, communicate.

Title: WRONG RWY APCH.

Narrative: CLRED FOR VISUAL TO RWY 17 A J MCO. FO FLYING ACFT. APCH CTLR ADVISED US OF TFC LNDG ON RWY 18R. HE APPEARED ON TCASII. SWITCHED OVER TO TWR AND TCASII GIVES US AN RA. ON INITIAL CONTACT I WAS LOOKING FOR ACFT THAT WAS GIVING RA AND COULD NOT HEAR TWR DUE TO TCASII. WHEN I LOOKED AT OUR POS, NOTICED FO WAS LINED UP FOR RWY 18L. IMMEDIATELY DIRECTED ACFT TO TURN BACK TO RWY 17 AND THEN GAVE FO THE ACFT BACK. CONTACTED TWR AGAIN (OR SIMULTANEOUSLY AS WE MOVED BACK). ON LNDG, TWR SAID NO PROB. FO REALIZED THINGS DIDN'T LOOK RIGHT BUT NEVER VOICED CONCERN UNTIL WE DISCUSSED IT ON GND. ONE OF THE UNDERLYING PROBS IN THIS EVENT WAS THAT WE WERE IN A SEMI-SLAM DUNK, THUS FASTER THAN NORMAL AIRSPD. I BELIEVE THIS CAUSED THE INITIAL OVERSHOOT AND THEN WHEN CONFUSED, THE FO DID NOT IMMEDIATELY VOICE HIS CONCERN. HE IS DEFINITELY AN ABOVE AVERAGE FO WHICH PROBABLY LULLED ME INTO CONCENTRATING ON THE RA THAN OUR CURRENT SIT. I DISCOVERED WHEN I TALKED WITH TWR (ON THE PHONE) THAT THEIR INITIAL CALL WAS FOR US TO IMMEDIATELY GET BACK TO RWY 17 WHICH WAS UNHEARD DUE TO TCASII. THE LESSON I'VE LEARNED: DON'T GET COMPLACENT WITH GOOD HELP, COMMUNICATE.
